See [Options](#options). +- `default`: a default value of the data instance, see [Assigning defaults](#assigning-defaults). +- `examples` (NEW in draft-07): an array of data instances. Ajv does not check the validity of these instances against the schema. +- `readOnly` and `writeOnly` (NEW in draft-07): marks data-instance as read-only or write-only in relation to the source of the data (database, api, etc.). +- `contentEncoding`: [RFC 2045](https://tools.ietf.org/html/rfc2045#section-6.1 ), e.g., "base64". +- `contentMediaType`: [RFC 2046](https://tools.ietf.org/html/rfc2046), e.g., "image/png". + +__Please note__: Ajv does not implement validation of the keywords `examples`, `contentEncoding` and `contentMediaType` but it reserves them. If you want to create a plugin that implements some of them, it should remove these keywords from the instance. + + +## Formats + +The following formats are supported for string validation with "format" keyword: + +- _date_: full-date according to [RFC3339](http://tools.ietf.org/html/rfc3339#section-5.6). +- _time_: time with optional time-zone. +- _date-time_: date-time from the same source (time-zone is mandatory). `date`, `time` and `date-time` validate ranges in `full` mode and only regexp in `fast` mode (see [options](#options)). +- _uri_: full URI. +- _uri-reference_: URI reference, including full and relative URIs. +- _uri-template_: URI template according to [RFC6570](https://tools.ietf.org/html/rfc6570) +- _url_ (deprecated): [URL record](https://url.spec.whatwg.org/#concept-url). +- _email_: email address. +- _hostname_: host name according to [RFC1034](http://tools.ietf.org/html/rfc1034#section-3.5). +- _ipv4_: IP address v4. +- _ipv6_: IP address v6. +- _regex_: tests whether a string is a valid regular expression by passing it to RegExp constructor. +- _uuid_: Universally Unique IDentifier according to [RFC4122](http://tools.ietf.org/html/rfc4122). +- _json-pointer_: JSON-pointer according to [RFC6901](https://tools.ietf.org/html/rfc6901). +- _relative-json-pointer_: relative JSON-pointer according to [this draft](http://tools.ietf.org/html/draft-luff-relative-json-pointer-00). + +__Please note__: JSON Schema draft-07 also defines formats `iri`, `iri-reference`, `idn-hostname` and `idn-email` for URLs, hostnames and emails with international characters. Ajv does not implement these formats. If you create Ajv plugin that implements them please make a PR to mention this plugin here. + +There are two modes of format validation: `fast` and `full`. This mode affects formats `date`, `time`, `date-time`, `uri`, `uri-reference`, `email`, and `hostname`. See [Options](#options) for details. + +You can add additional formats and replace any of the formats above using [addFormat](#api-addformat) method. + +The option `unknownFormats` allows changing the default behaviour when an unknown format is encountered. In this case Ajv can either fail schema compilation (default) or ignore it (default in versions before 5.0.0). You also can whitelist specific format(s) to be ignored. See [Options](#options) for details. + +You can find regular expressions used for format validation and the sources that were used in [formats.js](https://github.com/epoberezkin/ajv/blob/master/lib/compile/formats.js). + + +## Combining schemas with $ref + +You can structure your validation logic across multiple schema files and have schemas reference each other using `$ref` keyword. + +Example: + +```javascript +var schema = { + "$id": "http://example.com/schemas/schema.json", + "type": "object", + "properties": { + "foo": { "$ref": "defs.json#/definitions/int" }, + "bar": { "$ref": "defs.json#/definitions/str" } + } +}; + +var defsSchema = { + "$id": "http://example.com/schemas/defs.json", + "definitions": { + "int": { "type": "integer" }, + "str": { "type": "string" } + } +}; +``` + +Now to compile your schema you can either pass all schemas to Ajv instance: + +```javascript +var ajv = new Ajv({schemas: [schema, defsSchema]}); +var validate = ajv.getSchema('http://example.com/schemas/schema.json'); +``` + +or use `addSchema` method: + +```javascript +var ajv = new Ajv; +var validate = ajv.addSchema(defsSchema) + .compile(schema); +``` + +See [Options](#options) and [addSchema](#api) method. + +__Please note__: +- `$ref` is resolved as the uri-reference using schema $id as the base URI (see the example). +- References can be recursive (and mutually recursive) to implement the schemas for different data structures (such as linked lists, trees, graphs, etc.). +- You don't have to host your schema files at the URIs that you use as schema $id. These URIs are only used to identify the schemas, and according to JSON Schema specification validators should not expect to be able to download the schemas from these URIs. +- The actual location of the schema file in the file system is not used. +- You can pass the identifier of the schema as the second parameter of `addSchema` method or as a property name in `schemas` option. This identifier can be used instead of (or in addition to) schema $id. +- You cannot have the same $id (or the schema identifier) used for more than one schema - the exception will be thrown. +- You can implement dynamic resolution of the referenced schemas using `compileAsync` method. In this way you can store schemas in any system (files, web, database, etc.) and reference them without explicitly adding to Ajv instance. See [Asynchronous schema compilation](#asynchronous-schema-compilation). + + +## $data reference + +With `$data` option you can use values from the validated data as the values for the schema keywords. See [proposal](https://github.com/json-schema/json-schema/wiki/$data-(v5-proposal)) for more information about how it works. + +`$data` reference is supported in the keywords: const, enum, format, maximum/minimum, exclusiveMaximum / exclusiveMinimum, maxLength / minLength, maxItems / minItems, maxProperties / minProperties, formatMaximum / formatMinimum, formatExclusiveMaximum / formatExclusiveMinimum, multipleOf, pattern, required, uniqueItems. + +The value of "$data" should be a [JSON-pointer](https://tools.ietf.org/html/rfc6901) to the data (the root is always the top level data object, even if the $data reference is inside a referenced subschema) or a [relative JSON-pointer](http://tools.ietf.org/html/draft-luff-relative-json-pointer-00) (it is relative to the current point in data; if the $data reference is inside a referenced subschema it cannot point to the data outside of the root level for this subschema). + +Examples. + +This schema requires that the value in property `smaller` is less or equal than the value in the property larger: + +```javascript +var ajv = new Ajv({$data: true}); + +var schema = { + "properties": { + "smaller": { + "type": "number", + "maximum": { "$data": "1/larger" } + }, + "larger": { "type": "number" } + } +}; + +var validData = { + smaller: 5, + larger: 7 +}; + +ajv.validate(schema, validData); // true +``` + +This schema requires that the properties have the same format as their field names: + +```javascript +var schema = { + "additionalProperties": { + "type": "string", + "format": { "$data": "0#" } + } +}; + +var validData = { + 'date-time': '1963-06-19T08:30:06.283185Z', + email: 'joe.bloggs@example.com' +} +``` + +`$data` reference is resolved safely - it won't throw even if some property is undefined. If `$data` resolves to `undefined` the validation succeeds (with the exclusion of `const` keyword). If `$data` resolves to incorrect type (e.g. not "number" for maximum keyword) the validation fails. + + +## $merge and $patch keywords + +With the package [ajv-merge-patch](https://github.com/epoberezkin/ajv-merge-patch) you can use the keywords `$merge` and `$patch` that allow extending JSON Schemas with patches using formats [JSON Merge Patch (RFC 7396)](https://tools.ietf.org/html/rfc7396) and [JSON Patch (RFC 6902)](https://tools.ietf.org/html/rfc6902). + +To add keywords `$merge` and `$patch` to Ajv instance use this code: + +```javascript +require('ajv-merge-patch')(ajv); +``` + +Examples. + +Using `$merge`: + +```json +{ + "$merge": { + "source": { + "type": "object", + "properties": { "p": { "type": "string" } }, + "additionalProperties": false + }, + "with": { + "properties": { "q": { "type": "number" } } + } + } +} +``` + +Using `$patch`: + +```json +{ + "$patch": { + "source": { + "type": "object", + "properties": { "p": { "type": "string" } }, + "additionalProperties": false + }, + "with": [ + { "op": "add", "path": "/properties/q", "value": { "type": "number" } } + ] + } +} +``` + +The schemas above are equivalent to this schema: + +```json +{ + "type": "object", + "properties": { + "p": { "type": "string" }, + "q": { "type": "number" } + }, + "additionalProperties": false +} +``` + +The properties `source` and `with` in the keywords `$merge` and `$patch` can use absolute or relative `$ref` to point to other schemas previously added to the Ajv instance or to the fragments of the current schema. + +See the package [ajv-merge-patch](https://github.com/epoberezkin/ajv-merge-patch) for more information. + + +## Defining custom keywords + +The advantages of using custom keywords are: + +- allow creating validation scenarios that cannot be expressed using JSON Schema +- simplify your schemas +- help bringing a bigger part of the validation logic to your schemas +- make your schemas more expressive, less verbose and closer to your application domain +- implement custom data processors that modify your data (`modifying` option MUST be used in keyword definition) and/or create side effects while the data is being validated + +If a keyword is used only for side-effects and its validation result is pre-defined, use option `valid: true/false` in keyword definition to simplify both generated code (no error handling in case of `valid: true`) and your keyword functions (no need to return any validation result). + +The concerns you have to be aware of when extending JSON Schema standard with custom keywords are the portability and understanding of your schemas. You will have to support these custom keywords on other platforms and to properly document these keywords so that everybody can understand them in your schemas. + +You can define custom keywords with [addKeyword](#api-addkeyword) method. Keywords are defined on the `ajv` instance level - new instances will not have previously defined keywords. + +Ajv allows defining keywords with: +- validation function +- compilation function +- macro function +- inline compilation function that should return code (as string) that will be inlined in the currently compiled schema. + +Example. `range` and `exclusiveRange` keywords using compiled schema: + +```javascript +ajv.addKeyword('range', { + type: 'number', + compile: function (sch, parentSchema) { + var min = sch[0]; + var max = sch[1]; + + return parentSchema.exclusiveRange === true + ? function (data) { return data > min && data < max; } + : function (data) { return data >= min && data <= max; } + } +}); + +var schema = { "range": [2, 4], "exclusiveRange": true }; +var validate = ajv.compile(schema); +console.log(validate(2.01)); // true +console.log(validate(3.99)); // true +console.log(validate(2)); // false +console.log(validate(4)); // false +``` + +Several custom keywords (typeof, instanceof, range and propertyNames) are defined in [ajv-keywords](https://github.com/epoberezkin/ajv-keywords) package - they can be used for your schemas and as a starting point for your own custom keywords. + +See [Defining custom keywords](https://github.com/epoberezkin/ajv/blob/master/CUSTOM.md) for more details. + + +## Asynchronous schema compilation + +During asynchronous compilation remote references are loaded using supplied function. See `compileAsync` [method](#api-compileAsync) and `loadSchema` [option](#options). + +Example: + +```javascript +var ajv = new Ajv({ loadSchema: loadSchema }); + +ajv.compileAsync(schema).then(function (validate) { + var valid = validate(data); + // ... +}); + +function loadSchema(uri) { + return request.json(uri).then(function (res) { + if (res.statusCode >= 400) + throw new Error('Loading error: ' + res.statusCode); + return res.body; + }); +} +``` + +__Please note__: [Option](#options) `missingRefs` should NOT be set to `"ignore"` or `"fail"` for asynchronous compilation to work. + + +## Asynchronous validation + +Example in Node.js REPL: https://tonicdev.com/esp/ajv-asynchronous-validation + +You can define custom formats and keywords that perform validation asynchronously by accessing database or some other service. You should add `async: true` in the keyword or format definition (see [addFormat](#api-addformat), [addKeyword](#api-addkeyword) and [Defining custom keywords](#defining-custom-keywords)). + +If your schema uses asynchronous formats/keywords or refers to some schema that contains them it should have `"$async": true` keyword so that Ajv can compile it correctly. If asynchronous format/keyword or reference to asynchronous schema is used in the schema without `$async` keyword Ajv will throw an exception during schema compilation. + +__Please note__: all asynchronous subschemas that are referenced from the current or other schemas should have `"$async": true` keyword as well, otherwise the schema compilation will fail. + +Validation function for an asynchronous custom format/keyword should return a promise that resolves with `true` or `false` (or rejects with `new Ajv.ValidationError(errors)` if you want to return custom errors from the keyword function). + +Ajv compiles asynchronous schemas to [es7 async functions](http://tc39.github.io/ecmascript-asyncawait/) that can optionally be transpiled with [nodent](https://github.com/MatAtBread/nodent). Async functions are supported in Node.js 7+ and all modern browsers. You can also supply any other transpiler as a function via `processCode` option. See [Options](#options). + +The compiled validation function has `$async: true` property (if the schema is asynchronous), so you can differentiate these functions if you are using both synchronous and asynchronous schemas. + +Validation result will be a promise that resolves with validated data or rejects with an exception `Ajv.ValidationError` that contains the array of validation errors in `errors` property. + + +Example: + +```javascript +var ajv = new Ajv; +// require('ajv-async')(ajv); + +ajv.addKeyword('idExists', { + async: true, + type: 'number', + validate: checkIdExists +}); + + +function checkIdExists(schema, data) { + return knex(schema.table) + .select('id') + .where('id', data) + .then(function (rows) { + return !!rows.length; // true if record is found + }); +} + +var schema = { + "$async": true, + "properties": { + "userId": { + "type": "integer", + "idExists": { "table": "users" } + }, + "postId": { + "type": "integer", + "idExists": { "table": "posts" } + } + } +}; + +var validate = ajv.compile(schema); + +validate({ userId: 1, postId: 19 }) +.then(function (data) { + console.log('Data is valid', data); // { userId: 1, postId: 19 } +}) +.catch(function (err) { + if (!(err instanceof Ajv.ValidationError)) throw err; + // data is invalid + console.log('Validation errors:', err.errors); +}); +``` + +### Using transpilers with asynchronous validation functions. + +[ajv-async](https://github.com/epoberezkin/ajv-async) uses [nodent](https://github.com/MatAtBread/nodent) to transpile async functions. To use another transpiler you should separately install it (or load its bundle in the browser). + + +#### Using nodent + +```javascript +var ajv = new Ajv; +require('ajv-async')(ajv); +// in the browser if you want to load ajv-async bundle separately you can: +// window.ajvAsync(ajv); +var validate = ajv.compile(schema); // transpiled es7 async function +validate(data).then(successFunc).catch(errorFunc); +``` + + +#### Using other transpilers + +```javascript +var ajv = new Ajv({ processCode: transpileFunc }); +var validate = ajv.compile(schema); // transpiled es7 async function +validate(data).then(successFunc).catch(errorFunc); +``` + +See [Options](#options). + + +## Security considerations + +JSON Schema, if properly used, can replace data sanitisation. It doesn't replace other API security considerations. It also introduces additional security aspects to consider. + + +##### Untrusted schemas + +Ajv treats JSON schemas as trusted as your application code. This security model is based on the most common use case, when the schemas are static and bundled together with the application. + +If your schemas are received from untrusted sources (or generated from untrusted data) there are several scenarios you need to prevent: +- compiling schemas can cause stack overflow (if they are too deep) +- compiling schemas can be slow (e.g. [#557](https://github.com/epoberezkin/ajv/issues/557)) +- validating certain data can be slow + +It is difficult to predict all the scenarios, but at the very least it may help to limit the size of untrusted schemas (e.g. limit JSON string length) and also the maximum schema object depth (that can be high for relatively small JSON strings). You also may want to mitigate slow regular expressions in `pattern` and `patternProperties` keywords. + +Regardless the measures you take, using untrusted schemas increases security risks. + + +##### Circular references in JavaScript objects + +Ajv does not support schemas and validated data that have circular references in objects. See [issue #802](https://github.com/epoberezkin/ajv/issues/802). + +An attempt to compile such schemas or validate such data would cause stack overflow (or will not complete in case of asynchronous validation). Depending on the parser you use, untrusted data can lead to circular references. + + +##### Security risks of trusted schemas + +Some keywords in JSON Schemas can lead to very slow validation for certain data. These keywords include (but may be not limited to): + +- `pattern` and `format` for large strings - use `maxLength` to mitigate +- `uniqueItems` for large non-scalar arrays - use `maxItems` to mitigate +- `patternProperties` for large property names - use `propertyNames` to mitigate + +__Please note__: The suggestions above to prevent slow validation would only work if you do NOT use `allErrors: true` in production code (using it would continue validation after validation errors). + +You can validate your JSON schemas against [this meta-schema](https://github.com/epoberezkin/ajv/blob/master/lib/refs/json-schema-secure.json) to check that these recommendations are followed: + +```javascript +const isSchemaSecure = ajv.compile(require('ajv/lib/refs/json-schema-secure.json')); + +const schema1 = {format: 'email'}; +isSchemaSecure(schema1); // false + +const schema2 = {format: 'email', maxLength: 256}; +isSchemaSecure(schema2); // true +``` + +__Please note__: following all these recommendation is not a guarantee that validation of untrusted data is safe - it can still lead to some undesirable results. + + +## Filtering data + +With [option `removeAdditional`](#options) (added by [andyscott](https://github.com/andyscott)) you can filter data during the validation. + +This option modifies original data. + +Example: + +```javascript +var ajv = new Ajv({ removeAdditional: true }); +var schema = { + "additionalProperties": false, + "properties": { + "foo": { "type": "number" }, + "bar": { + "additionalProperties": { "type": "number" }, + "properties": { + "baz": { "type": "string" } + } + } + } +} + +var data = { + "foo": 0, + "additional1": 1, // will be removed; `additionalProperties` == false + "bar": { + "baz": "abc", + "additional2": 2 // will NOT be removed; `additionalProperties` != false + }, +} + +var validate = ajv.compile(schema); + +console.log(validate(data)); // true +console.log(data); // { "foo": 0, "bar": { "baz": "abc", "additional2": 2 } +``` + +If `removeAdditional` option in the example above were `"all"` then both `additional1` and `additional2` properties would have been removed. + +If the option were `"failing"` then property `additional1` would have been removed regardless of its value and property `additional2` would have been removed only if its value were failing the schema in the inner `additionalProperties` (so in the example above it would have stayed because it passes the schema, but any non-number would have been removed). + +__Please note__: If you use `removeAdditional` option with `additionalProperties` keyword inside `anyOf`/`oneOf` keywords your validation can fail with this schema, for example: + +```json +{ + "type": "object", + "oneOf": [ + { + "properties": { + "foo": { "type": "string" } + }, + "required": [ "foo" ], + "additionalProperties": false + }, + { + "properties": { + "bar": { "type": "integer" } + }, + "required": [ "bar" ], + "additionalProperties": false + } + ] +} +``` + +The intention of the schema above is to allow objects with either the string property "foo" or the integer property "bar", but not with both and not with any other properties. + +With the option `removeAdditional: true` the validation will pass for the object `{ "foo": "abc"}` but will fail for the object `{"bar": 1}`. It happens because while the first subschema in `oneOf` is validated, the property `bar` is removed because it is an additional property according to the standard (because it is not included in `properties` keyword in the same schema). + +While this behaviour is unexpected (issues [#129](https://github.com/epoberezkin/ajv/issues/129), [#134](https://github.com/epoberezkin/ajv/issues/134)), it is correct. To have the expected behaviour (both objects are allowed and additional properties are removed) the schema has to be refactored in this way: + +```json +{ + "type": "object", + "properties": { + "foo": { "type": "string" }, + "bar": { "type": "integer" } + }, + "additionalProperties": false, + "oneOf": [ + { "required": [ "foo" ] }, + { "required": [ "bar" ] } + ] +} +``` + +The schema above is also more efficient - it will compile into a faster function. + + +## Assigning defaults + +With [option `useDefaults`](#options) Ajv will assign values from `default` keyword in the schemas of `properties` and `items` (when it is the array of schemas) to the missing properties and items. + +With the option value `"empty"` properties and items equal to `null` or `""` (empty string) will be considered missing and assigned defaults. + +This option modifies original data. + +__Please note__: the default value is inserted in the generated validation code as a literal, so the value inserted in the data will be the deep clone of the default in the schema. + + +Example 1 (`default` in `properties`): + +```javascript +var ajv = new Ajv({ useDefaults: true }); +var schema = { + "type": "object", + "properties": { + "foo": { "type": "number" }, + "bar": { "type": "string", "default": "baz" } + }, + "required": [ "foo", "bar" ] +}; + +var data = { "foo": 1 }; + +var validate = ajv.compile(schema); + +console.log(validate(data)); // true +console.log(data); // { "foo": 1, "bar": "baz" } +``` + +Example 2 (`default` in `items`): + +```javascript +var schema = { + "type": "array", + "items": [ + { "type": "number" }, + { "type": "string", "default": "foo" } + ] +} + +var data = [ 1 ]; + +var validate = ajv.compile(schema); + +console.log(validate(data)); // true +console.log(data); // [ 1, "foo" ] +``` + +`default` keywords in other cases are ignored: + +- not in `properties` or `items` subschemas +- in schemas inside `anyOf`, `oneOf` and `not` (see [#42](https://github.com/epoberezkin/ajv/issues/42)) +- in `if` subschema of `switch` keyword +- in schemas generated by custom macro keywords + + +## Coercing data types + +When you are validating user inputs all your data properties are usually strings. The option `coerceTypes` allows you to have your data types coerced to the types specified in your schema `type` keywords, both to pass the validation and to use the correctly typed data afterwards. + +This option modifies original data. + +__Please note__: if you pass a scalar value to the validating function its type will be coerced and it will pass the validation, but the value of the variable you pass won't be updated because scalars are passed by value. + + +Example 1: + +```javascript +var ajv = new Ajv({ coerceTypes: true }); +var schema = { + "type": "object", + "properties": { + "foo": { "type": "number" }, + "bar": { "type": "boolean" } + }, + "required": [ "foo", "bar" ] +}; + +var data = { "foo": "1", "bar": "false" }; + +var validate = ajv.compile(schema); + +console.log(validate(data)); // true +console.log(data); // { "foo": 1, "bar": false } +``` + +Example 2 (array coercions): + +```javascript +var ajv = new Ajv({ coerceTypes: 'array' }); +var schema = { + "properties": { + "foo": { "type": "array", "items": { "type": "number" } }, + "bar": { "type": "boolean" } + } +}; + +var data = { "foo": "1", "bar": ["false"] }; + +var validate = ajv.compile(schema); + +console.log(validate(data)); // true +console.log(data); // { "foo": [1], "bar": false } +``` + +The coercion rules, as you can see from the example, are different from JavaScript both to validate user input as expected and to have the coercion reversible (to correctly validate cases where different types are defined in subschemas of "anyOf" and other compound keywords). + +See [Coercion rules](https://github.com/epoberezkin/ajv/blob/master/COERCION.md) for details. + + +## API + +##### new Ajv(Object options) -> Object + +Create Ajv instance. + + +##### .compile(Object schema) -> Function<Object data> + +Generate validating function and cache the compiled schema for future use. + +Validating function returns a boolean value. This function has properties `errors` and `schema`. Errors encountered during the last validation are assigned to `errors` property (it is assigned `null` if there was no errors). `schema` property contains the reference to the original schema. + +The schema passed to this method will be validated against meta-schema unless `validateSchema` option is false. If schema is invalid, an error will be thrown. See [options](#options). + + +##### .compileAsync(Object schema [, Boolean meta] [, Function callback]) -> Promise + +Asynchronous version of `compile` method that loads missing remote schemas using asynchronous function in `options.loadSchema`. This function returns a Promise that resolves to a validation function. An optional callback passed to `compileAsync` will be called with 2 parameters: error (or null) and validating function. The returned promise will reject (and the callback will be called with an error) when: + +- missing schema can't be loaded (`loadSchema` returns a Promise that rejects). +- a schema containing a missing reference is loaded, but the reference cannot be resolved. +- schema (or some loaded/referenced schema) is invalid. + +The function compiles schema and loads the first missing schema (or meta-schema) until all missing schemas are loaded. + +You can asynchronously compile meta-schema by passing `true` as the second parameter. + +See example in [Asynchronous compilation](#asynchronous-schema-compilation). + + +##### .validate(Object schema|String key|String ref, data) -> Boolean + +Validate data using passed schema (it will be compiled and cached). + +Instead of the schema you can use the key that was previously passed to `addSchema`, the schema id if it was present in the schema or any previously resolved reference. + +Validation errors will be available in the `errors` property of Ajv instance (`null` if there were no errors). + +__Please note__: every time this method is called the errors are overwritten so you need to copy them to another variable if you want to use them later. + +If the schema is asynchronous (has `$async` keyword on the top level) this method returns a Promise. See [Asynchronous validation](#asynchronous-validation). + + +##### .addSchema(Array<Object>|Object schema [, String key]) -> Ajv + +Add schema(s) to validator instance. This method does not compile schemas (but it still validates them). Because of that dependencies can be added in any order and circular dependencies are supported. It also prevents unnecessary compilation of schemas that are containers for other schemas but not used as a whole. + +Array of schemas can be passed (schemas should have ids), the second parameter will be ignored. + +Key can be passed that can be used to reference the schema and will be used as the schema id if there is no id inside the schema. If the key is not passed, the schema id will be used as the key. + + +Once the schema is added, it (and all the references inside it) can be referenced in other schemas and used to validate data. + +Although `addSchema` does not compile schemas, explicit compilation is not required - the schema will be compiled when it is used first time. + +By default the schema is validated against meta-schema before it is added, and if the schema does not pass validation the exception is thrown. This behaviour is controlled by `validateSchema` option. + +__Please note__: Ajv uses the [method chaining syntax](https://en.wikipedia.org/wiki/Method_chaining) for all methods with the prefix `add*` and `remove*`. +This allows you to do nice things like the following. + +```javascript +var validate = new Ajv().addSchema(schema).addFormat(name, regex).getSchema(uri); +``` + +##### .addMetaSchema(Array<Object>|Object schema [, String key]) -> Ajv + +Adds meta schema(s) that can be used to validate other schemas. That function should be used instead of `addSchema` because there may be instance options that would compile a meta schema incorrectly (at the moment it is `removeAdditional` option). + +There is no need to explicitly add draft-07 meta schema (http://json-schema.org/draft-07/schema) - it is added by default, unless option `meta` is set to `false`. You only need to use it if you have a changed meta-schema that you want to use to validate your schemas. See `validateSchema`. + + +##### .validateSchema(Object schema) -> Boolean + +Validates schema. This method should be used to validate schemas rather than `validate` due to the inconsistency of `uri` format in JSON Schema standard. + +By default this method is called automatically when the schema is added, so you rarely need to use it directly. + +If schema doesn't have `$schema` property, it is validated against draft 6 meta-schema (option `meta` should not be false). + +If schema has `$schema` property, then the schema with this id (that should be previously added) is used to validate passed schema. + +Errors will be available at `ajv.errors`. + + +##### .getSchema(String key) -> Function<Object data> + +Retrieve compiled schema previously added with `addSchema` by the key passed to `addSchema` or by its full reference (id). The returned validating function has `schema` property with the reference to the original schema. + + +##### .removeSchema([Object schema|String key|String ref|RegExp pattern]) -> Ajv + +Remove added/cached schema. Even if schema is referenced by other schemas it can be safely removed as dependent schemas have local references. + +Schema can be removed using: +- key passed to `addSchema` +- it's full reference (id) +- RegExp that should match schema id or key (meta-schemas won't be removed) +- actual schema object that will be stable-stringified to remove schema from cache + +If no parameter is passed all schemas but meta-schemas will be removed and the cache will be cleared. + + +##### .addFormat(String name, String|RegExp|Function|Object format) -> Ajv + +Add custom format to validate strings or numbers. It can also be used to replace pre-defined formats for Ajv instance. + +Strings are converted to RegExp. + +Function should return validation result as `true` or `false`. + +If object is passed it should have properties `validate`, `compare` and `async`: + +- _validate_: a string, RegExp or a function as described above. +- _compare_: an optional comparison function that accepts two strings and compares them according to the format meaning. This function is used with keywords `formatMaximum`/`formatMinimum` (defined in [ajv-keywords](https://github.com/epoberezkin/ajv-keywords) package). It should return `1` if the first value is bigger than the second value, `-1` if it is smaller and `0` if it is equal. +- _async_: an optional `true` value if `validate` is an asynchronous function; in this case it should return a promise that resolves with a value `true` or `false`. +- _type_: an optional type of data that the format applies to. It can be `"string"` (default) or `"number"` (see https://github.com/epoberezkin/ajv/issues/291#issuecomment-259923858). If the type of data is different, the validation will pass. + +Custom formats can be also added via `formats` option. + + +##### .addKeyword(String keyword, Object definition) -> Ajv + +Add custom validation keyword to Ajv instance. + +Keyword should be different from all standard JSON Schema keywords and different from previously defined keywords. There is no way to redefine keywords or to remove keyword definition from the instance. + +Keyword must start with a letter, `_` or `$`, and may continue with letters, numbers, `_`, `$`, or `-`. +It is recommended to use an application-specific prefix for keywords to avoid current and future name collisions. + +Example Keywords: +- `"xyz-example"`: valid, and uses prefix for the xyz project to avoid name collisions. +- `"example"`: valid, but not recommended as it could collide with future versions of JSON Schema etc. +- `"3-example"`: invalid as numbers are not allowed to be the first character in a keyword + +Keyword definition is an object with the following properties: + +- _type_: optional string or array of strings with data type(s) that the keyword applies to. If not present, the keyword will apply to all types. +- _validate_: validating function +- _compile_: compiling function +- _macro_: macro function +- _inline_: compiling function that returns code (as string) +- _schema_: an optional `false` value used with "validate" keyword to not pass schema +- _metaSchema_: an optional meta-schema for keyword schema +- _dependencies_: an optional list of properties that must be present in the parent schema - it will be checked during schema compilation +- _modifying_: `true` MUST be passed if keyword modifies data +- _statements_: `true` can be passed in case inline keyword generates statements (as opposed to expression) +- _valid_: pass `true`/`false` to pre-define validation result, the result returned from validation function will be ignored. This option cannot be used with macro keywords. +- _$data_: an optional `true` value to support [$data reference](#data-reference) as the value of custom keyword. The reference will be resolved at validation time. If the keyword has meta-schema it would be extended to allow $data and it will be used to validate the resolved value. Supporting $data reference requires that keyword has validating function (as the only option or in addition to compile, macro or inline function). +- _async_: an optional `true` value if the validation function is asynchronous (whether it is compiled or passed in _validate_ property); in this case it should return a promise that resolves with a value `true` or `false`. This option is ignored in case of "macro" and "inline" keywords. +- _errors_: an optional boolean or string `"full"` indicating whether keyword returns errors. If this property is not set Ajv will determine if the errors were set in case of failed validation. + +_compile_, _macro_ and _inline_ are mutually exclusive, only one should be used at a time. _validate_ can be used separately or in addition to them to support $data reference. + +__Please note__: If the keyword is validating data type that is different from the type(s) in its definition, the validation function will not be called (and expanded macro will not be used), so there is no need to check for data type inside validation function or inside schema returned by macro function (unless you want to enforce a specific type and for some reason do not want to use a separate `type` keyword for that). In the same way as standard keywords work, if the keyword does not apply to the data type being validated, the validation of this keyword will succeed. + +See [Defining custom keywords](#defining-custom-keywords) for more details. + + +##### .getKeyword(String keyword) -> Object|Boolean + +Returns custom keyword definition, `true` for pre-defined keywords and `false` if the keyword is unknown. + + +##### .removeKeyword(String keyword) -> Ajv + +Removes custom or pre-defined keyword so you can redefine them. + +While this method can be used to extend pre-defined keywords, it can also be used to completely change their meaning - it may lead to unexpected results. + +__Please note__: schemas compiled before the keyword is removed will continue to work without changes. To recompile schemas use `removeSchema` method and compile them again. + + +##### .errorsText([Array<Object> errors [, Object options]]) -> String + +Returns the text with all errors in a String. + +Options can have properties `separator` (string used to separate errors, ", " by default) and `dataVar` (the variable name that dataPaths are prefixed with, "data" by default). + + +## Options + +Defaults: + +```javascript +{ + // validation and reporting options: + $data: false, + allErrors: false, + verbose: false, + $comment: false, // NEW in Ajv version 6.0 + jsonPointers: false, + uniqueItems: true, + unicode: true, + nullable: false, + format: 'fast', + formats: {}, + unknownFormats: true, + schemas: {}, + logger: undefined, + // referenced schema options: + schemaId: '$id', + missingRefs: true, + extendRefs: 'ignore', // recommended 'fail' + loadSchema: undefined, // function(uri: string): Promise {} + // options to modify validated data: + removeAdditional: false, + useDefaults: false, + coerceTypes: false, + // asynchronous validation options: + transpile: undefined, // requires ajv-async package + // advanced options: + meta: true, + validateSchema: true, + addUsedSchema: true, + inlineRefs: true, + passContext: false, + loopRequired: Infinity, + ownProperties: false, + multipleOfPrecision: false, + errorDataPath: 'object', // deprecated + messages: true, + sourceCode: false, + processCode: undefined, // function (str: string): string {} + cache: new Cache, + serialize: undefined +} +``` + +##### Validation and reporting options + +- _$data_: support [$data references](#data-reference). Draft 6 meta-schema that is added by default will be extended to allow them. If you want to use another meta-schema you need to use $dataMetaSchema method to add support for $data reference. See [API](#api). +- _allErrors_: check all rules collecting all errors. Default is to return after the first error. +- _verbose_: include the reference to the part of the schema (`schema` and `parentSchema`) and validated data in errors (false by default). +- _$comment_ (NEW in Ajv version 6.0): log or pass the value of `$comment` keyword to a function. Option values: + - `false` (default): ignore $comment keyword. + - `true`: log the keyword value to console. + - function: pass the keyword value, its schema path and root schema to the specified function +- _jsonPointers_: set `dataPath` property of errors using [JSON Pointers](https://tools.ietf.org/html/rfc6901) instead of JavaScript property access notation. +- _uniqueItems_: validate `uniqueItems` keyword (true by default). +- _unicode_: calculate correct length of strings with unicode pairs (true by default). Pass `false` to use `.length` of strings that is faster, but gives "incorrect" lengths of strings with unicode pairs - each unicode pair is counted as two characters. +- _nullable_: support keyword "nullable" from [Open API 3 specification](https://swagger.io/docs/specification/data-models/data-types/). +- _format_: formats validation mode. Option values: + - `"fast"` (default) - simplified and fast validation (see [Formats](#formats) for details of which formats are available and affected by this option). + - `"full"` - more restrictive and slow validation. E.g., 25:00:00 and 2015/14/33 will be invalid time and date in 'full' mode but it will be valid in 'fast' mode. + - `false` - ignore all format keywords. +- _formats_: an object with custom formats. Keys and values will be passed to `addFormat` method. +- _unknownFormats_: handling of unknown formats. Option values: + - `true` (default) - if an unknown format is encountered the exception is thrown during schema compilation. If `format` keyword value is [$data reference](#data-reference) and it is unknown the validation will fail. + - `[String]` - an array of unknown format names that will be ignored. This option can be used to allow usage of third party schemas with format(s) for which you don't have definitions, but still fail if another unknown format is used. If `format` keyword value is [$data reference](#data-reference) and it is not in this array the validation will fail. + - `"ignore"` - to log warning during schema compilation and always pass validation (the default behaviour in versions before 5.0.0). This option is not recommended, as it allows to mistype format name and it won't be validated without any error message. This behaviour is required by JSON Schema specification. +- _schemas_: an array or object of schemas that will be added to the instance. In case you pass the array the schemas must have IDs in them. When the object is passed the method `addSchema(value, key)` will be called for each schema in this object. +- _logger_: sets the logging method. Default is the global `console` object that should have methods `log`, `warn` and `error`. Option values: + - custom logger - it should have methods `log`, `warn` and `error`. If any of these methods is missing an exception will be thrown. + - `false` - logging is disabled. + + +##### Referenced schema options + +- _schemaId_: this option defines which keywords are used as schema URI. Option value: + - `"$id"` (default) - only use `$id` keyword as schema URI (as specified in JSON Schema draft-06/07), ignore `id` keyword (if it is present a warning will be logged). + - `"id"` - only use `id` keyword as schema URI (as specified in JSON Schema draft-04), ignore `$id` keyword (if it is present a warning will be logged). + - `"auto"` - use both `$id` and `id` keywords as schema URI. If both are present (in the same schema object) and different the exception will be thrown during schema compilation. +- _missingRefs_: handling of missing referenced schemas. Option values: + - `true` (default) - if the reference cannot be resolved during compilation the exception is thrown. The thrown error has properties `missingRef` (with hash fragment) and `missingSchema` (without it). Both properties are resolved relative to the current base id (usually schema id, unless it was substituted). + - `"ignore"` - to log error during compilation and always pass validation. + - `"fail"` - to log error and successfully compile schema but fail validation if this rule is checked. +- _extendRefs_: validation of other keywords when `$ref` is present in the schema. Option values: + - `"ignore"` (default) - when `$ref` is used other keywords are ignored (as per [JSON Reference](https://tools.ietf.org/html/draft-pbryan-zyp-json-ref-03#section-3) standard). A warning will be logged during the schema compilation. + - `"fail"` (recommended) - if other validation keywords are used together with `$ref` the exception will be thrown when the schema is compiled. This option is recommended to make sure schema has no keywords that are ignored, which can be confusing. + - `true` - validate all keywords in the schemas with `$ref` (the default behaviour in versions before 5.0.0). +- _loadSchema_: asynchronous function that will be used to load remote schemas when `compileAsync` [method](#api-compileAsync) is used and some reference is missing (option `missingRefs` should NOT be 'fail' or 'ignore'). This function should accept remote schema uri as a parameter and return a Promise that resolves to a schema. See example in [Asynchronous compilation](#asynchronous-schema-compilation). + + +##### Options to modify validated data + +- _removeAdditional_: remove additional properties - see example in [Filtering data](#filtering-data). This option is not used if schema is added with `addMetaSchema` method. Option values: + - `false` (default) - not to remove additional properties + - `"all"` - all additional properties are removed, regardless of `additionalProperties` keyword in schema (and no validation is made for them). + - `true` - only additional properties with `additionalProperties` keyword equal to `false` are removed. + - `"failing"` - additional properties that fail schema validation will be removed (where `additionalProperties` keyword is `false` or schema). +- _useDefaults_: replace missing or undefined properties and items with the values from corresponding `default` keywords. Default behaviour is to ignore `default` keywords. This option is not used if schema is added with `addMetaSchema` method. See examples in [Assigning defaults](#assigning-defaults). Option values: + - `false` (default) - do not use defaults + - `true` - insert defaults by value (object literal is used). + - `"empty"` - in addition to missing or undefined, use defaults for properties and items that are equal to `null` or `""` (an empty string). + - `"shared"` (deprecated) - insert defaults by reference. If the default is an object, it will be shared by all instances of validated data. If you modify the inserted default in the validated data, it will be modified in the schema as well. +- _coerceTypes_: change data type of data to match `type` keyword. See the example in [Coercing data types](#coercing-data-types) and [coercion rules](https://github.com/epoberezkin/ajv/blob/master/COERCION.md). Option values: + - `false` (default) - no type coercion. + - `true` - coerce scalar data types. + - `"array"` - in addition to coercions between scalar types, coerce scalar data to an array with one element and vice versa (as required by the schema). + + +##### Asynchronous validation options + +- _transpile_: Requires [ajv-async](https://github.com/epoberezkin/ajv-async) package. It determines whether Ajv transpiles compiled asynchronous validation function. Option values: + - `undefined` (default) - transpile with [nodent](https://github.com/MatAtBread/nodent) if async functions are not supported. + - `true` - always transpile with nodent. + - `false` - do not transpile; if async functions are not supported an exception will be thrown. + + +##### Advanced options + +- _meta_: add [meta-schema](http://json-schema.org/documentation.html) so it can be used by other schemas (true by default). If an object is passed, it will be used as the default meta-schema for schemas that have no `$schema` keyword. This default meta-schema MUST have `$schema` keyword. +- _validateSchema_: validate added/compiled schemas against meta-schema (true by default). `$schema` property in the schema can be http://json-schema.org/draft-07/schema or absent (draft-07 meta-schema will be used) or can be a reference to the schema previously added with `addMetaSchema` method. Option values: + - `true` (default) - if the validation fails, throw the exception. + - `"log"` - if the validation fails, log error. + - `false` - skip schema validation. +- _addUsedSchema_: by default methods `compile` and `validate` add schemas to the instance if they have `$id` (or `id`) property that doesn't start with "#". If `$id` is present and it is not unique the exception will be thrown. Set this option to `false` to skip adding schemas to the instance and the `$id` uniqueness check when these methods are used. This option does not affect `addSchema` method. +- _inlineRefs_: Affects compilation of referenced schemas. Option values: + - `true` (default) - the referenced schemas that don't have refs in them are inlined, regardless of their size - that substantially improves performance at the cost of the bigger size of compiled schema functions. + - `false` - to not inline referenced schemas (they will be compiled as separate functions). + - integer number - to limit the maximum number of keywords of the schema that will be inlined. +- _passContext_: pass validation context to custom keyword functions. If this option is `true` and you pass some context to the compiled validation function with `validate.call(context, data)`, the `context` will be available as `this` in your custom keywords. By default `this` is Ajv instance. +- _loopRequired_: by default `required` keyword is compiled into a single expression (or a sequence of statements in `allErrors` mode). In case of a very large number of properties in this keyword it may result in a very big validation function. Pass integer to set the number of properties above which `required` keyword will be validated in a loop - smaller validation function size but also worse performance. +- _ownProperties_: by default Ajv iterates over all enumerable object properties; when this option is `true` only own enumerable object properties (i.e. found directly on the object rather than on its prototype) are iterated. Contributed by @mbroadst. +- _multipleOfPrecision_: by default `multipleOf` keyword is validated by comparing the result of division with parseInt() of that result. It works for dividers that are bigger than 1. For small dividers such as 0.01 the result of the division is usually not integer (even when it should be integer, see issue [#84](https://github.com/epoberezkin/ajv/issues/84)). If you need to use fractional dividers set this option to some positive integer N to have `multipleOf` validated using this formula: `Math.abs(Math.round(division) - division) < 1e-N` (it is slower but allows for float arithmetics deviations). +- _errorDataPath_ (deprecated): set `dataPath` to point to 'object' (default) or to 'property' when validating keywords `required`, `additionalProperties` and `dependencies`. +- _messages_: Include human-readable messages in errors. `true` by default. `false` can be passed when custom messages are used (e.g. with [ajv-i18n](https://github.com/epoberezkin/ajv-i18n)). +- _sourceCode_: add `sourceCode` property to validating function (for debugging; this code can be different from the result of toString call). +- _processCode_: an optional function to process generated code before it is passed to Function constructor. It can be used to either beautify (the validating function is generated without line-breaks) or to transpile code. Starting from version 5.0.0 this option replaced options: + - `beautify` that formatted the generated function using [js-beautify](https://github.com/beautify-web/js-beautify). If you want to beautify the generated code pass `require('js-beautify').js_beautify`. + - `transpile` that transpiled asynchronous validation function. You can still use `transpile` option with [ajv-async](https://github.com/epoberezkin/ajv-async) package. See [Asynchronous validation](#asynchronous-validation) for more information. +- _cache_: an optional instance of cache to store compiled schemas using stable-stringified schema as a key. For example, set-associative cache [sacjs](https://github.com/epoberezkin/sacjs) can be used. If not passed then a simple hash is used which is good enough for the common use case (a limited number of statically defined schemas). Cache should have methods `put(key, value)`, `get(key)`, `del(key)` and `clear()`. +- _serialize_: an optional function to serialize schema to cache key. Pass `false` to use schema itself as a key (e.g., if WeakMap used as a cache). By default [fast-json-stable-stringify](https://github.com/epoberezkin/fast-json-stable-stringify) is used. + + +## Validation errors + +In case of validation failure, Ajv assigns the array of errors to `errors` property of validation function (or to `errors` property of Ajv instance when `validate` or `validateSchema` methods were called). In case of [asynchronous validation](#asynchronous-validation), the returned promise is rejected with exception `Ajv.ValidationError` that has `errors` property. + + +### Error objects + +Each error is an object with the following properties: + +- _keyword_: validation keyword. +- _dataPath_: the path to the part of the data that was validated. By default `dataPath` uses JavaScript property access notation (e.g., `".prop[1].subProp"`). When the option `jsonPointers` is true (see [Options](#options)) `dataPath` will be set using JSON pointer standard (e.g., `"/prop/1/subProp"`). +- _schemaPath_: the path (JSON-pointer as a URI fragment) to the schema of the keyword that failed validation. +- _params_: the object with the additional information about error that can be used to create custom error messages (e.g., using [ajv-i18n](https://github.com/epoberezkin/ajv-i18n) package). See below for parameters set by all keywords. +- _message_: the standard error message (can be excluded with option `messages` set to false). +- _schema_: the schema of the keyword (added with `verbose` option). +- _parentSchema_: the schema containing the keyword (added with `verbose` option) +- _data_: the data validated by the keyword (added with `verbose` option). + +__Please note__: `propertyNames` keyword schema validation errors have an additional property `propertyName`, `dataPath` points to the object. After schema validation for each property name, if it is invalid an additional error is added with the property `keyword` equal to `"propertyNames"`. + + +### Error parameters + +Properties of `params` object in errors depend on the keyword that failed validation. + +- `maxItems`, `minItems`, `maxLength`, `minLength`, `maxProperties`, `minProperties` - property `limit` (number, the schema of the keyword). +- `additionalItems` - property `limit` (the maximum number of allowed items in case when `items` keyword is an array of schemas and `additionalItems` is false). +- `additionalProperties` - property `additionalProperty` (the property not used in `properties` and `patternProperties` keywords). +- `dependencies` - properties: + - `property` (dependent property), + - `missingProperty` (required missing dependency - only the first one is reported currently) + - `deps` (required dependencies, comma separated list as a string), + - `depsCount` (the number of required dependencies). +- `format` - property `format` (the schema of the keyword). +- `maximum`, `minimum` - properties: + - `limit` (number, the schema of the keyword), + - `exclusive` (boolean, the schema of `exclusiveMaximum` or `exclusiveMinimum`), + - `comparison` (string, comparison operation to compare the data to the limit, with the data on the left and the limit on the right; can be "<", "<=", ">", ">=") +- `multipleOf` - property `multipleOf` (the schema of the keyword) +- `pattern` - property `pattern` (the schema of the keyword) +- `required` - property `missingProperty` (required property that is missing). +- `propertyNames` - property `propertyName` (an invalid property name). +- `patternRequired` (in ajv-keywords) - property `missingPattern` (required pattern that did not match any property). +- `type` - property `type` (required type(s), a string, can be a comma-separated list) +- `uniqueItems` - properties `i` and `j` (indices of duplicate items). +- `const` - property `allowedValue` pointing to the value (the schema of the keyword). +- `enum` - property `allowedValues` pointing to the array of values (the schema of the keyword). +- `$ref` - property `ref` with the referenced schema URI. +- `oneOf` - property `passingSchemas` (array of indices of passing schemas, null if no schema passes). +- custom keywords (in case keyword definition doesn't create errors) - property `keyword` (the keyword name). + + +## Plugins + +Ajv can be extended with plugins that add custom keywords, formats or functions to process generated code.

This allows you +to code to the AMD API and have the module work in node programs without +requiring those other programs to use AMD. + +## Usage + +**1)** Update your package.json to indicate amdefine as a dependency: + +```javascript + "dependencies": { + "amdefine": ">=0.1.0" + } +``` + +Then run `npm install` to get amdefine into your project. + +**2)** At the top of each module that uses define(), place this code: + +```javascript +if (typeof define !== 'function') { var define = require('amdefine')(module) } +``` + +**Only use these snippets** when loading amdefine. If you preserve the basic structure, +with the braces, it will be stripped out when using the [RequireJS optimizer](#optimizer). + +You can add spaces, line breaks and even require amdefine with a local path, but +keep the rest of the structure to get the stripping behavior. + +As you may know, because `if` statements in JavaScript don't have their own scope, the var +declaration in the above snippet is made whether the `if` expression is truthy or not. If +RequireJS is loaded then the declaration is superfluous because `define` is already already +declared in the same scope in RequireJS. Fortunately JavaScript handles multiple `var` +declarations of the same variable in the same scope gracefully. + +If you want to deliver amdefine.js with your code rather than specifying it as a dependency +with npm, then just download the latest release and refer to it using a relative path: + +[Latest Version](https://github.com/jrburke/amdefine/raw/latest/amdefine.js) + +### amdefine/intercept + +Consider this very experimental. + +Instead of pasting the piece of text for the amdefine setup of a `define` +variable in each module you create or consume, you can use `amdefine/intercept` +instead. It will automatically insert the above snippet in each .js file loaded +by Node. + +**Warning**: you should only use this if you are creating an application that +is consuming AMD style defined()'d modules that are distributed via npm and want +to run that code in Node. + +For library code where you are not sure if it will be used by others in Node or +in the browser, then explicitly depending on amdefine and placing the code +snippet above is suggested path, instead of using `amdefine/intercept`. The +intercept module affects all .js files loaded in the Node app, and it is +inconsiderate to modify global state like that unless you are also controlling +the top level app. + +#### Why distribute AMD-style modules via npm? + +npm has a lot of weaknesses for front-end use (installed layout is not great, +should have better support for the `baseUrl + moduleID + '.js' style of loading, +single file JS installs), but some people want a JS package manager and are +willing to live with those constraints. If that is you, but still want to author +in AMD style modules to get dynamic require([]), better direct source usage and +powerful loader plugin support in the browser, then this tool can help. + +#### amdefine/intercept usage + +Just require it in your top level app module (for example index.js, server.js): + +```javascript +require('amdefine/intercept'); +``` + +The module does not return a value, so no need to assign the result to a local +variable. + +Then just require() code as you normally would with Node's require(). Any .js +loaded after the intercept require will have the amdefine check injected in +the .js source as it is loaded. It does not modify the source on disk, just +prepends some content to the text of the module as it is loaded by Node. + +#### How amdefine/intercept works + +It overrides the `Module._extensions['.js']` in Node to automatically prepend +the amdefine snippet above. So, it will affect any .js file loaded by your +app. + +## define() usage + +It is best if you use the anonymous forms of define() in your module: + +```javascript +define(function (require) { + var dependency = require('dependency'); +}); +``` + +or + +```javascript +define(['dependency'], function (dependency) { + +}); +``` + +## RequireJS optimizer integration. + +Version 1.0.3 of the [RequireJS optimizer](http://requirejs.org/docs/optimization.html) +will have support for stripping the `if (typeof define !== 'function')` check +mentioned above, so you can include this snippet for code that runs in the +browser, but avoid taking the cost of the if() statement once the code is +optimized for deployment. + +## Node 0.4 Support + +If you want to support Node 0.4, then add `require` as the second parameter to amdefine: + +```javascript +//Only if you want Node 0.4. If using 0.5 or later, use the above snippet. +if (typeof define !== 'function') { var define = require('amdefine')(module, require) } +``` + +## Limitations + +### Synchronous vs Asynchronous + +amdefine creates a define() function that is callable by your code. It will +execute and trace dependencies and call the factory function *synchronously*, +to keep the behavior in line with Node's synchronous dependency tracing. + +The exception: calling AMD's callback-style require() from inside a factory +function. The require callback is called on process.nextTick(): + +```javascript +define(function (require) { + require(['a'], function(a) { + //'a' is loaded synchronously, but + //this callback is called on process.nextTick(). + }); +}); +``` + +### Loader Plugins + +Loader plugins are supported as long as they call their load() callbacks +synchronously. So ones that do network requests will not work. However plugins +like [text](http://requirejs.org/docs/api.html#text) can load text files locally. + +The plugin API's `load.fromText()` is **not supported** in amdefine, so this means +transpiler plugins like the [CoffeeScript loader plugin](https://github.com/jrburke/require-cs) +will not work. This may be fixable, but it is a bit complex, and I do not have +enough node-fu to figure it out yet. See the source for amdefine.js if you want +to get an idea of the issues involved. + +## Tests + +To run the tests, cd to **tests** and run: + +``` +node all.js +node all-intercept.js +``` + +## License + +New BSD and MIT.

+`require("asap/raw")`. +The interface is the same for both layers. + +Tasks are no longer required to be functions, but can rather be any object that +implements `task.call()`. +With this feature you can recycle task objects to avoid garbage collector churn +and avoid closures in general. + +The implementation has been rigorously documented so that our successors can +understand the scope of the problem that this module solves and all of its +nuances, ensuring that the next generation of implementations know what details +are essential. + +-

asynchronous observer libraries, as well as hand-rolled callback +programs and libraries, often need a mechanism to postpone the execution of a +callback until the next available event. +(See [Designing API’s for Asynchrony][Zalgo].) +The `asap` function executes a task **as soon as possible** but not before it +returns, waiting only for the completion of the current event and previously +scheduled tasks. + +```javascript +asap(function () { + // ... +}); +``` + +[Zalgo]: http://blog.izs.me/post/59142742143/designing-apis-for-asynchrony + +This CommonJS package provides an `asap` module that exports a function that +executes a task function *as soon as possible*. + +ASAP strives to schedule events to occur before yielding for IO, reflow, +or redrawing. +Each event receives an independent stack, with only platform code in parent +frames and the events run in the order they are scheduled. + +ASAP provides a fast event queue that will execute tasks until it is +empty before yielding to the JavaScript engine's underlying event-loop. +When a task gets added to a previously empty event queue, ASAP schedules a flush +event, preferring for that event to occur before the JavaScript engine has an +opportunity to perform IO tasks or rendering, thus making the first task and +subsequent tasks semantically indistinguishable. +ASAP uses a variety of techniques to preserve this invariant on different +versions of browsers and Node.js. + +By design, ASAP prevents input events from being handled until the task +queue is empty. +If the process is busy enough, this may cause incoming connection requests to be +dropped, and may cause existing connections to inform the sender to reduce the +transmission rate or stall. +ASAP allows this on the theory that, if there is enough work to do, there is no +sense in looking for trouble. +As a consequence, ASAP can interfere with smooth animation. +If your task should be tied to the rendering loop, consider using +`requestAnimationFrame` instead. +A long sequence of tasks can also effect the long running script dialog. +If this is a problem, you may be able to use ASAP’s cousin `setImmediate` to +break long processes into shorter intervals and periodically allow the browser +to breathe. +`setImmediate` will yield for IO, reflow, and repaint events. +It also returns a handler and can be canceled. +For a `setImmediate` shim, consider [YuzuJS setImmediate][setImmediate]. + +[setImmediate]: https://github.com/YuzuJS/setImmediate + +Take care. +ASAP can sustain infinite recursive calls without warning. +It will not halt from a stack overflow, and it will not consume unbounded +memory. +This is behaviorally equivalent to an infinite loop. +Just as with infinite loops, you can monitor a Node.js process for this behavior +with a heart-beat signal. +As with infinite loops, a very small amount of caution goes a long way to +avoiding problems. + +```javascript +function loop() { + asap(loop); +} +loop(); +``` + +In browsers, if a task throws an exception, it will not interrupt the flushing +of high-priority tasks. +The exception will be postponed to a later, low-priority event to avoid +slow-downs. +In Node.js, if a task throws an exception, ASAP will resume flushing only if—and +only after—the error is handled by `domain.on("error")` or +`process.on("uncaughtException")`. + +## Raw ASAP + +Checking for exceptions comes at a cost. +The package also provides an `asap/raw` module that exports the underlying +implementation which is faster but stalls if a task throws an exception. +This internal version of the ASAP function does not check for errors. +If a task does throw an error, it will stall the event queue unless you manually +call `rawAsap.requestFlush()` before throwing the error, or any time after. + +In Node.js, `asap/raw` also runs all tasks outside any domain. +If you need a task to be bound to your domain, you will have to do it manually. + +```js +if (process.domain) { + task = process.domain.bind(task); +} +rawAsap(task); +``` + +## Tasks + +A task may be any object that implements `call()`. +A function will suffice, but closures tend not to be reusable and can cause +garbage collector churn. +Both `asap` and `rawAsap` accept task objects to give you the option of +recycling task objects or using higher callable object abstractions. +See the `asap` source for an illustration. + + +## Compatibility + +ASAP is tested on Node.js v0.10 and in a broad spectrum of web browsers. +The following charts capture the browser test results for the most recent +release. +The first chart shows test results for ASAP running in the main window context. +The second chart shows test results for ASAP running in a web worker context. +Test results are

in some of the above browsers, where [message channels][] +would be a useful way to avoid falling back to timers. +Message channels give direct access to the HTML [task queue][], so the ASAP +task queue would flush after any already queued rendering and IO tasks, but +without having the minimum delay imposed by timers. +However, among these browsers, Internet Explorer 10 and Safari do not reliably +dispatch messages, so they are not worth the trouble to implement. + +[message channels]: http://www.whatwg.org/specs/web-apps/current-work/multipage/web-messaging.html#message-channels

`setTimeout`, but +[Malte Ubl][NonBlocking] provided an insight that `postMessage` might be +useful for creating a high-priority, no-delay event dispatch hack. +Since then, Internet Explorer proposed and implemented `setImmediate`. +Robert Katić began contributing to Q by measuring the performance of +the internal implementation of `asap`, paying particular attention to +error recovery. +Domenic, Robert, and Kris Kowal collectively settled on the current strategy of +unrolling the high-priority event queue internally regardless of what strategy +we used to dispatch the potentially lower-priority flush event. +Domenic went on to make ASAP cooperate with Node.js domains. + +[Q]: https://github.com/kriskowal/q +[NonBlocking]: http://www.nonblocking.io/2011/06/windownexttick.html +

promise implementation later [adopted][RSVP ASAP] the name ASAP but +further developed the implentation. +Particularly, The `MessagePort` implementation was abandoned due to interaction +[problems with Mobile Internet Explorer][IE Problems] in favor of an +implementation backed on the newer and more reliable DOM `MutationObserver` +interface. +These changes were back-ported into this library. + +[IE Problems]: https://github.com/cujojs/when/issues/197 +[RSVP ASAP]: https://github.com/tildeio/rsvp.js/blob/cddf7232546a9cf858524b75cde6f9edf72620a7/lib/rsvp/asap.js + +In addition, ASAP factored into `asap` and `asap/raw`, such that `asap` remained +exception-safe, but `asap/raw` provided a tight kernel that could be used for +tasks that guaranteed that they would not throw exceptions. +This core is useful for promise implementations that capture thrown errors in +rejected promises and do not need a second safety net. +At the same time, the exception handling in `asap` was factored into

Like +`assert.string(myArg, 'myArg')`. As a simple example, most of my code looks +like this: + +```javascript + var assert = require('assert-plus'); + + function fooAccount(options, callback) { + assert.object(options, 'options'); + assert.number(options.id, 'options.id'); + assert.bool(options.isManager, 'options.isManager'); + assert.string(options.name, 'options.name'); + assert.arrayOfString(options.email, 'options.email'); + assert.func(callback, 'callback'); + + // Do stuff + callback(null, {}); + } +``` + +# API + +All methods that *aren't* part of node's core assert API are simply assumed to +take an argument, and then a string 'name' that's not a message; `AssertionError` +will be thrown if the assertion fails with a message like: + + AssertionError: foo (string) is required + at test (/home/mark/work/foo/foo.js:3:9) + at Object.

The function is +idempotent, and also emits a `'resume'` event each time which usually goes to +the stream that is currently being drained. + +### combinedStream.pause(); + +If `combinedStream.pauseStreams` is set to `false`, this does nothing. +Otherwise a `'pause'` event is emitted, this goes to the stream that is +currently being drained, so you can use it to apply back pressure. + +### combinedStream.end(); + +Sets `combinedStream.writable` to false, emits an `'end'` event, and removes +all streams from the queue. + +### combinedStream.destroy(); + +Same as `combinedStream.end()`, except it emits a `'close'` event instead of +`'end'`. + +## License + +combined-stream is licensed under the MIT license. diff --git a/node_modules/combined-stream/lib/combined_stream.js b/node_modules/combined-stream/lib/combined_stream.js new file mode 100644 index 0000000000..809b3c2e7d --- /dev/null +++ b/node_modules/combined-stream/lib/combined_stream.js @@ -0,0 +1,189 @@ +var util = require('util');

Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc. + +Note that multi-word options starting with `--no` prefix negate the boolean value of the following word. For example, `--no-sauce` sets the value of `program.sauce` to false. + +```js +#!/usr/bin/env node + +/** + * Module dependencies. + */ + +var program = require('commander'); + +program + .option('--no-sauce', 'Remove sauce') + .parse(process.argv); + +console.log('you ordered a pizza'); +if (program.sauce) console.log(' with sauce'); +else console.log(' without sauce'); +``` + +## Version option + +Calling the `version` implicitly adds the `-V` and `--version` options to the command. +When either of these options is present, the command prints the version number and exits. + + $ ./examples/pizza -V + 0.0.1 + +If you want your program to respond to the `-v` option instead of the `-V` option, simply pass custom flags to the `version` method using the same syntax as the `option` method. + +```js +program + .version('0.0.1', '-v, --version') +``` + +The version flags can be named anything, but the long option is required. + +## Command-specific options + +You can attach options to a command. + +```js +#!/usr/bin/env node + +var program = require('commander'); + +program + .command('rm ') + .option('-r, --recursive', 'Remove recursively') + .action(function (dir, cmd) { + console.log('remove ' + dir + (cmd.recursive ?

This tells commander that you're going to use separate executables for sub-commands, much like `git(1)` and other popular tools. +The commander will try to search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-command`, like `pm-install`, `pm-search`. + +Options can be passed with the call to `.command()`. Specifying `true` for `opts.noHelp` will remove the subcommand from the generated help output. Specifying `true` for `opts.isDefault` will run the subcommand if no other subcommand is specified. + +If the program is designed to be installed globally, make sure the executables have proper modes, like `755`. + +### `--harmony` + +You can enable `--harmony` option in two ways: +* Use `#! /usr/bin/env node --harmony` in the sub-commands scripts. Note some os version don’t support this pattern. +* Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning sub-command process. + +## Automated --help + + The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free: + +``` +$ ./examples/pizza --help +Usage: pizza [options] + +An application for pizzas ordering + +Options: + -h, --help output usage information + -V, --version output the version number + -p, --peppers Add peppers + -P, --pineapple Add pineapple + -b, --bbq Add bbq sauce + -c, --cheese Add the specified type of cheese [marble] + -C, --no-cheese You do not want any cheese +``` + +## Custom help + + You can display arbitrary `-h, --help` information + by listening for "--help". Commander will automatically + exit once you are done so that the remainder of your program + does not execute causing undesired behaviors, for example + in the following executable "stuff" will not output when + `--help` is used. + +```js +#!/usr/bin/env node + +/** + * Module dependencies. + */ + +var program = require('commander');

See + [node-cmdln](https://github.com/trentm/node-cmdln#bash-completion) for + how to integrate that. +- Does the right thing with "--" to stop options. +- Custom optarg and arg types for custom completions. + +Dashdash will return bash completion file content given a parser instance: + + var parser = dashdash.createParser({options: options}); + console.log( parser.bashCompletion({name: 'mycli'}) ); + +or directly from a `options` array of options specs: + + var code = dashdash.bashCompletionFromOptions({ + name: 'mycli', + options: OPTIONS + }); + +Write that content to "/usr/local/etc/bash_completion.d/mycli" and you will +have Bash completions for `mycli`. Alternatively you can write it to +any file (e.g. "~/.bashrc") and source it. + +You could add a `--completion` hidden option to your tool that emits the +completion content and document for your users to call that to install +Bash completions. + +See [examples/ddcompletion.js](examples/ddcompletion.js) for a complete +example, including how one can define bash functions for completion of custom +option types. Also see [node-cmdln](https://github.com/trentm/node-cmdln) for +how it uses this for Bash completion for full multi-subcommand tools. + +- TODO: document specExtra +- TODO: document includeHidden +- TODO: document custom types, `function complete\_FOO` guide, completionType +- TODO: document argtypes + + +# Parser config + +Parser construction (i.e. `dashdash.createParser(CONFIG)`) takes the +following fields: + +- `options` (Array of option specs). Required. See the + [Option specs](#option-specs) section below. + +- `interspersed` (Boolean). Optional. Default is true. If true this allows + interspersed arguments and options. I.e.: + + node ./tool.js -v arg1 arg2 -h # '-h' is after interspersed args + + Set it to false to have '-h' **not** get parsed as an option in the above + example. + +- `allowUnknown` (Boolean).

I.e.: + + node ./tool.js -v arg1 --afe8asefksjefhas + + Set it to true to treat the unknown option as a positional + argument. + + **Caveat**: When a shortopt group, such as `-xaz` contains a mix of + known and unknown options, the *entire* group is passed through + unmolested as a positional argument. + + Consider if you have a known short option `-a`, and parse the + following command line: + + node ./tool.js -xaz + + where `-x` and `-z` are unknown. There are multiple ways to + interpret this: + + 1. `-x` takes a value: `{x: 'az'}` + 2. `-x` and `-z` are both booleans: `{x:true,a:true,z:true}` + + Since dashdash does not know what `-x` and `-z` are, it can't know + if you'd prefer to receive `{a:true,_args:['-x','-z']}` or + `{x:'az'}`, or `{_args:['-xaz']}`.

Any string may be specified, but only the + following values have meaning: + + - `none`: Provide no completions. + - `file`: Bash's default completion (i.e. `complete -o default`), which + includes filenames. + - *Any string FOO for which a `function complete_FOO` Bash function is + defined.* This is for custom completions for a given tool. Typically + these custom functions are provided in the `specExtra` argument to + `dashdash.bashCompletionFromOptions()`. See + ["examples/ddcompletion.js"](examples/ddcompletion.js) for an example. + +- `env` (String or Array of String). Optional. An environment variable name + (or names) that can be used as a fallback for this option. For example, + given a "foo.js" like this: + + var options = [{names: ['dry-run', 'n'], env: 'FOO_DRY_RUN'}]; + var opts = dashdash.parse({options: options}); + + Both `node foo.js --dry-run` and `FOO_DRY_RUN=1 node foo.js` would result + in `opts.dry_run = true`. + + An environment variable is only used as a fallback, i.e. it is ignored if + the associated option is given in `argv`. + +- `help` (String). Optional. Used for `parser.help()` output. + +- `helpArg` (String). Optional. Used in help output as the placeholder for + the option argument, e.g. the "PATH" in: + + ... + -f PATH, --file=PATH File to process + ... + +- `helpWrap` (Boolean). Optional, default true. Set this to `false` to have + that option's `help` *not* be text wrapped in `.help()` output. + +- `default`. Optional. A default value used for this option, if the + option isn't specified in argv. + +- `hidden` (Boolean). Optional, default false. If true, help output will not + include this option. See also the `includeHidden` option to + `bashCompletionFromOptions()` for [Bash completion](#bash-completion). + + +# Option group headings + +You can add headings between option specs in the `options` array.

Default 4. Set to a number (for that many + spaces) or a string for the literal indent. +- `headingIndent` (Number or String). Default half length of `indent`. Set to + a number (for that many spaces) or a string for the literal indent. This + indent applies to group heading lines, between normal option lines. +- `nameSort` (String). Default is 'length'. By default the names are + sorted to put the short opts first (i.e. '-h, --help' preferred + to '--help, -h'). Set to 'none' to not do this sorting. +- `maxCol` (Number). Default 80. Note that reflow is just done on whitespace + so a long token in the option help can overflow maxCol. +- `helpCol` (Number). If not set a reasonable value will be determined + between `minHelpCol` and `maxHelpCol`. +- `minHelpCol` (Number). Default 20. +- `maxHelpCol` (Number). Default 40. +- `helpWrap` (Boolean). Default true. Set to `false` to have option `help` + strings *not* be textwrapped to the helpCol..maxCol range. +- `includeEnv` (Boolean). Default false. If the option has associated + environment variables (via the `env` option spec attribute), then + append mentioned of those envvars to the help string. +- `includeDefault` (Boolean). Default false.

Until node implements a catch-all event listener, this is the only way. + +However, delayed-stream still continues to emit all events it captures on the +`source`, regardless of whether you have released the delayed stream yet or +not. + +Upon creation, delayed-stream captures all `source` events and stores them in +an internal event buffer. Once `delayedStream.release()` is called, all +buffered events are emitted on the `delayedStream`, and the event buffer is +cleared. After that, delayed-stream merely acts as a proxy for the underlaying +source. + +### Error handling + +Error events on `source` are buffered / proxied just like any other events. +However, `delayedStream.create` attaches a no-op `'error'` listener to the +`source`. This way you only have to handle errors on the `delayedStream` +object, rather than in two places. + +### Buffer limits + +delayed-stream provides a `maxDataSize` property that can be used to limit +the amount of data being buffered. In order to protect you from bad `source` +streams that don't react to `source.pause()`, this feature is enabled by +default. + +## API + +### DelayedStream.create(source, [options]) + +Returns a new `delayedStream`. Available options are: + +* `pauseStream` +* `maxDataSize` + +The description for those properties can be found below. + +### delayedStream.source + +The `source` stream managed by this object. This is useful if you are +passing your `delayedStream` around, and you still want to access properties +on the `source` object. + +### delayedStream.pauseStream = true + +Whether to pause the underlaying `source` when calling +`DelayedStream.create()`. Modifying this property afterwards has no effect. + +### delayedStream.maxDataSize = 1024 * 1024 + +The amount of data to buffer before emitting an `error`. + +If the underlaying source is emitting `Buffer` objects, the `maxDataSize` +refers to bytes. + +If the underlaying source is emitting JavaScript strings, the size refers to +characters. + +If you know what you are doing, you can set this property to `Infinity` to +disable this feature. You can also modify this property during runtime. + +### delayedStream.dataSize = 0 + +The amount of data buffered so far. + +### delayedStream.readable + +An ECMA5 getter that returns the value of `source.readable`. + +### delayedStream.resume() + +If the `delayedStream` has not been released so far, `delayedStream.release()` +is called. + +In either case, `source.resume()` is called. + +### delayedStream.pause() + +Calls `source.pause()`. + +### delayedStream.pipe(dest) + +Calls `delayedStream.resume()` and then proxies the arguments to `source.pipe`. + +### delayedStream.release() + +Emits and clears all events that have been buffered up so far.

Braced sections start with `{` and end with `}`, with any +number of comma-delimited sections within. Braced sections may contain +slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`. + +The following characters have special magic meaning when used in a +path portion: + +* `*` Matches 0 or more characters in a single path portion +* `?` Matches 1 character +* `[...]` Matches a range of characters, similar to a RegExp range. + If the first character of the range is `!` or `^` then it matches + any character not in the range. +* `!(pattern|pattern|pattern)` Matches anything that does not match + any of the patterns provided. +* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the + patterns provided. +* `+(pattern|pattern|pattern)` Matches one or more occurrences of the + patterns provided. +* `*(a|b|c)` Matches zero or more occurrences of the patterns provided +* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns + provided +* `**` If a "globstar" is alone in a path portion, then it matches + zero or more directories and subdirectories searching for matches. + It does not crawl symlinked directories. + +### Dots + +If a file or directory path portion has a `.` as the first character, +then it will not match any glob pattern unless that pattern's +corresponding path part also has a `.` as its first character. + +For example, the pattern `a/.*/c` would match the file at `a/.b/c`. +However the pattern `a/*/c` would not, because `*` does not start with +a dot character. + +You can make glob treat dots as normal characters by setting +`dot:true` in the options. + +### Basename Matching + +If you set `matchBase:true` in the options, and the pattern has no +slashes in it, then it will seek for any file anywhere in the tree +with a matching basename. For example, `*.js` would match +`test/simple/basic.js`. + +### Empty Sets + +If no matching files are found, then an empty array is returned.

It is stored on the instantiated + Glob object, and may be re-used. + +### Events + +* `end` When the matching is finished, this is emitted with all the + matches found. If the `nonull` option is set, and no match was found, + then the `matches` list contains the original pattern. The matches + are sorted, unless the `nosort` flag is set. +* `match` Every time a match is found, this is emitted with the specific + thing that matched. It is not deduplicated or resolved to a realpath. +* `error` Emitted when an unexpected error is encountered, or whenever + any fs error occurs if `options.strict` is set. +* `abort` When `abort()` is called, this event is raised. + +### Methods + +* `pause` Temporarily stop the search +* `resume` Resume the search +* `abort` Stop the search forever + +### Options + +All the options that can be passed to Minimatch can also be passed to +Glob to change pattern matching behavior. Also, some have been added, +or have glob-specific ramifications. + +All options are false by default, unless otherwise noted. + +All options are added to the Glob object, as well. + +If you are running many `glob` operations, you can pass a Glob object +as the `options` argument to a subsequent operation to shortcut some +`stat` and `readdir` calls. At the very least, you may pass in shared +`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that +parallel glob operations will be sped up by sharing information about +the filesystem. + +* `cwd` The current working directory in which to search. Defaults + to `process.cwd()`. +* `root` The place where patterns starting with `/` will be mounted + onto. Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix + systems, and `C:\` or some such on Windows.) +* `dot` Include `.dot` files in normal matches and `globstar` matches. + Note that an explicit dot in a portion of the pattern will always + match dot files. +* `nomount` By default, a pattern starting with a forward-slash will be + "mounted" onto the root setting, so that a valid filesystem path is + returned. Set this flag to disable that behavior. +* `mark` Add a `/` character to directory matches. Note that this + requires additional stat calls. +* `nosort` Don't sort the results. +* `stat` Set to true to stat *all* results. This reduces performance + somewhat, and is completely unnecessary, unless `readdir` is presumed + to be an untrustworthy indicator of file existence. +* `silent` When an unusual error is encountered when attempting to + read a directory, a warning will be printed to stderr. Set the + `silent` option to true to suppress these warnings. +* `strict` When an unusual error is encountered when attempting to + read a directory, the process will just continue on in search of + other matches. Set the `strict` option to raise an error in these + cases. +* `cache` See `cache` property above. Pass in a previously generated + cache object to save some fs calls. +* `statCache` A cache of results of filesystem information, to prevent + unnecessary stat calls. While it should not normally be necessary + to set this, you may pass the statCache from one glob() call to the + options object of another, if you know that the filesystem will not + change between calls. (See "Race Conditions" below.) +* `symlinks` A cache of known symbolic links. You may pass in a + previously generated `symlinks` object to save `lstat` calls when + resolving `**` matches. +* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead. +* `nounique` In some cases, brace-expanded patterns can result in the + same file showing up multiple times in the result set. By default, + this implementation prevents duplicates in the result set. Set this + flag to disable that behavior. +* `nonull` Set to never return an empty set, instead returning a set + containing the pattern itself. This is the default in glob(3). +* `debug` Set to enable debug logging in minimatch and glob. +* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets. +* `noglobstar` Do not match `**` against multiple filenames. (Ie, + treat it as a normal `*` instead.) +* `noext` Do not match `+(a|b)` "extglob" patterns. +* `nocase` Perform a case-insensitive match. Note: on + case-insensitive filesystems, non-magic patterns will match by + default, since `stat` and `readdir` will not raise errors. +* `matchBase` Perform a basename-only match if the pattern does not + contain any slash characters. That is, `*.js` would be treated as + equivalent to `**/*.js`, matching all js files in all directories. +* `nodir` Do not match directories, only files. (Note: to match + *only* directories, simply put a `/` at the end of the pattern.) +* `ignore` Add a pattern or an array of glob patterns to exclude matches. + Note: `ignore` patterns are *always* in `dot:true` mode, regardless + of any other settings. +* `follow` Follow symlinked directories when expanding `**` patterns. + Note that this can result in a lot of duplicate references in the + presence of cyclic links. +* `realpath` Set to true to call `fs.realpath` on all of the results. + In the case of a symlink that cannot be resolved, the full absolute + path to the matched entry is returned (though it will usually be a + broken symlink) +* `absolute` Set to true to always receive absolute paths for matched + files. Unlike `realpath`, this also affects the values returned in + the `match` event. + +## Comparisons to other fnmatch/glob implementations + +While strict compliance with the existing standards is a worthwhile +goal, some discrepancies exist between node-glob and other +implementations, and are intentional. + +The double-star character `**` is supported by default, unless the +`noglobstar` flag is set. This is supported in the manner of bsdglob +and bash 4.3, where `**` only has special significance if it is the only +thing in a path part. That is, `a/**/b` will match `a/x/y/b`, but +`a/**b` will not. + +Note that symlinked directories are not crawled as part of a `**`, +though their contents may match against subsequent portions of the +pattern. This prevents infinite loops and duplicates and the like. + +If an escaped pattern has no matches, and the `nonull` flag is set, +then glob returns the pattern as-provided, rather than +interpreting the character escapes. For example, +`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than +`"*a?"`. This is akin to setting the `nullglob` option in bash, except +that it does not resolve escaped pattern characters. + +If brace expansion is not disabled, then it is performed before any +other interpretation of the glob pattern. Thus, a pattern like +`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded +**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are +checked for validity. Since those two are valid, matching proceeds. + +### Comments and Negation + +Previously, this module let you mark a pattern as a "comment" if it +started with a `#` character, or a "negated" pattern if it started +with a `!` character. + +These options were deprecated in version 5, and removed in version 6. + +To specify things that should not match, use the `ignore` option. + +## Windows + +**Please only use forward-slashes in glob expressions.** + +Though windows uses either `/` or `\` as its path separator, only `/` +characters are used by this glob implementation. You must use +forward-slashes **only** in glob expressions. Back-slashes will always +be interpreted as escape characters, not path separators. + +Results from absolute patterns such as `/foo/*` are mounted onto the +root setting using `path.join`. On windows, this will by default result +in `/foo/*` matching `C:\foo\bar.txt`. + +## Race Conditions + +Glob searching, by its very nature, is susceptible to race conditions, +since it relies on directory walking and such. + +As a result, it is possible that a file that exists when glob looks for +it may have been deleted or modified by the time it returns the result. + +As part of its internal implementation, this program caches all stat +and readdir calls that it makes, in order to cut down on system +overhead. However, this also makes it even more susceptible to races, +especially if the cache or statCache objects are reused between glob +calls. + +Users are thus advised not to use a glob result as a guarantee of +filesystem state in the face of rapid changes. For the vast majority +of operations, this is never a problem. + +## Contributing + +Any change to behavior (including bugfixes) must come with a test. + +Patches that fail tests or reduce performance will be rejected. + +``` +# to run tests +npm test + +# to re-generate test fixtures +npm run test-regen + +# to benchmark against bash/zsh +npm run bench + +# to profile javascript +npm run prof +```

That being said, because it implements a subtle behavior +change in a core part of the node API, even modest changes can be +extremely breaking, and the versioning is thus biased towards +bumping the major when in doubt. + +The main change between major versions has been switching between +providing a fully-patched `fs` module vs monkey-patching the node core +builtin, and the approach by which a non-monkey-patched `fs` was +created. + +The goal is to trade `EMFILE` errors for slower fs operations. So, if +you try to open a zillion files, rather than crashing, `open` +operations will be queued up and wait for something else to `close`. + +There are advantages to each approach. Monkey-patching the fs means +that no `EMFILE` errors can possibly occur anywhere in your +application, because everything is using the same core `fs` module, +which is patched. However, it can also obviously cause undesirable +side-effects, especially if the module is loaded multiple times. + +Implementing a separate-but-identical patched `fs` module is more +surgical (and doesn't run the risk of patching multiple times), but +also imposes the challenge of keeping in sync with the core module. + +The current approach loads the `fs` module, and then creates a +lookalike object that has all the same methods, except a few that are +patched. It is safe to use in all versions of Node from 0.8 through +7.0. + +### v4 + +* Do not monkey-patch the fs module. This module may now be used as a + drop-in dep, and users can opt into monkey-patching the fs builtin + if their app requires it. + +### v3 + +* Monkey-patch fs, because the eval approach no longer works on recent + node. +* fixed possible type-error throw if rename fails on windows +* verify that we *never* get EMFILE errors +* Ignore ENOSYS from chmod/chown +* clarify that graceful-fs must be used as a drop-in + +### v2.1.0 + +* Use eval rather than monkey-patching fs. +* readdir: Always sort the results +* win32: requeue a file if error has an OK status + +### v2.0 + +* A return to monkey patching +* wrap process.cwd + +### v1.1 + +* wrap readFile +* Wrap fs.writeFile. +* readdir protection +* Don't clobber the fs builtin +* Handle fs.read EAGAIN errors by trying again +* Expose the curOpen counter +* No-op lchown/lchmod if not implemented +* fs.rename patch only for win32 +* Patch fs.rename to handle AV software on Windows +* Close #4 Chown should not fail on einval or eperm if non-root +* Fix isaacs/fstream#1 Only wrap fs one time +* Fix #3 Start at 1024 max files, then back off on EMFILE +* lutimes that doens't blow up on Linux +* A full on-rewrite using a queue instead of just swallowing the EMFILE error +* Wrap Read/Write streams as well + +### 1.0 + +* Update engines for node 0.6 +* Be lstat-graceful on Windows +* first diff --git a/node_modules/graceful-fs/clone.js b/node_modules/graceful-fs/clone.js new file mode 100644 index 0000000000..028356c96e --- /dev/null +++ b/node_modules/graceful-fs/clone.js @@ -0,0 +1,19 @@ +'use strict' + +module.exports = clone + +function clone (obj) { + if (obj === null || typeof obj !== 'object') + return obj + + if (obj instanceof Object) + var copy = { __proto__: obj.__proto__ } + else + var copy = Object.create(null) + + Object.getOwnPropertyNames(obj).forEach(function (key) { + Object.defineProperty(copy, key, Object.getOwnPropertyDescriptor(obj, key)) + }) + + return copy +} diff --git a/node_modules/graceful-fs/graceful-fs.js b/node_modules/graceful-fs/graceful-fs.js new file mode 100644 index 0000000000..ac206757e6 --- /dev/null +++ b/node_modules/graceful-fs/graceful-fs.js @@ -0,0 +1,279 @@ +var fs = require('fs') +var polyfills = require('./polyfills.js') +var legacy = require('./legacy-streams.js') +var clone = require('./clone.js') + +var queue = [] + +var util = require('util') + +function noop () {} + +var debug = noop +if (util.debuglog) + debug = util.debuglog('gfs4') +else if (/\bgfs4\b/i.test(process.env.NODE_DEBUG || '')) + debug = function() { + var m = util.format.apply(util, arguments) + m = 'GFS4: ' + m.split(/\n/).join('\nGFS4: ') + console.error(m) + } + +if (/\bgfs4\b/i.test(process.env.NODE_DEBUG || '')) { + process.on('exit', function() { + debug(queue) + require('assert').equal(queue.length, 0) + }) +} + +module.exports = patch(clone(fs)) +if (process.env.TEST_GRACEFUL_FS_GLOBAL_PATCH && !fs.__patched) { + module.exports = patch(fs) + fs.__patched = true; +} + +// Always patch fs.close/closeSync, because we want to +// retry() whenever a close happens *anywhere* in the program. +// This is essential when multiple graceful-fs instances are +// in play at the same time. +module.exports.close = (function (fs$close) { return function (fd, cb) { + return fs$close.call(fs, fd, function (err) { + if (!err) + retry() + + if (typeof cb === 'function') + cb.apply(this, arguments) + }) +}})(fs.close) + +module.exports.closeSync = (function (fs$closeSync) { return function (fd) { + // Note that graceful-fs also retries when fs.closeSync() fails. + // Looks like a bug to me, although it's probably a harmless one. + var rval = fs$closeSync.apply(fs, arguments) + retry() + return rval +}})(fs.closeSync) + +// Only patch fs once, otherwise we'll run into a memory leak if +// graceful-fs is loaded multiple times, such as in test environments that +// reset the loaded modules between tests. +// We look for the string `graceful-fs` from the comment above.

RFC2617 (HTTP Authentication) defines Basic and Digest authentication +mechanisms, and RFC5246 (TLS 1.2) defines client-auth, both of which are widely +employed on the Internet today. However, it is common place that the burdens of +PKI prevent web service operators from deploying that methodology, and so many +fall back to Basic authentication, which has poor security characteristics. + +Additionally, OAuth provides a fully-specified alternative for authorization +of web service requests, but is not (always) ideal for machine to machine +communication, as the key acquisition steps (generally) imply a fixed +infrastructure that may not make sense to a service provider (e.g., symmetric +keys). + +Several web service providers have invented their own schemes for signing +HTTP requests, but to date, none have been placed in the public domain as a +standard. This document serves that purpose. There are no techniques in this +proposal that are novel beyond previous art, however, this aims to be a simple +mechanism for signing these requests. + +# Signature Authentication Scheme + +The "signature" authentication scheme is based on the model that the client must +authenticate itself with a digital signature produced by either a private +asymmetric key (e.g., RSA) or a shared symmetric key (e.g., HMAC). The scheme +is parameterized enough such that it is not bound to any particular key type or +signing algorithm. However, it does explicitly assume that clients can send an +HTTP `Date` header. + +## Authorization Header + +The client is expected to send an Authorization header (as defined in RFC 2617) +with the following parameterization: + + credentials := "Signature" params + params := 1#(keyId | algorithm | [headers] | [ext] | signature) + digitalSignature := plain-string + + keyId := "keyId" "=" <"> plain-string <"> + algorithm := "algorithm" "=" <"> plain-string <"> + headers := "headers" "=" <"> 1#headers-value <"> + ext := "ext" "=" <"> plain-string <"> + signature := "signature" "=" <"> plain-string <"> + + headers-value := plain-string + plain-string = 1*( %x20-21 / %x23-5B / %x5D-7E ) + +### Signature Parameters + +#### keyId + +REQUIRED. The `keyId` field is an opaque string that the server can use to look +up the component they need to validate the signature. It could be an SSH key +fingerprint, an LDAP DN, etc. Management of keys and assignment of `keyId` is +out of scope for this document. + +#### algorithm + +REQUIRED. The `algorithm` parameter is used if the client and server agree on a +non-standard digital signature algorithm. The full list of supported signature +mechanisms is listed below. + +#### headers + +OPTIONAL. The `headers` parameter is used to specify the list of HTTP headers +used to sign the request. If specified, it should be a quoted list of HTTP +header names, separated by a single space character. By default, only one +HTTP header is signed, which is the `Date` header. Note that the list MUST be +specified in the order the values are concatenated together during signing. To +include the HTTP request line in the signature calculation, use the special +`request-line` value. While this is overloading the definition of `headers` in +HTTP linguism, the request-line is defined in RFC 2616, and as the outlier from +headers in useful signature calculation, it is deemed simpler to simply use +`request-line` than to add a separate parameter for it. + +#### extensions + +OPTIONAL. The `extensions` parameter is used to include additional information +which is covered by the request. The content and format of the string is out of +scope for this document, and expected to be specified by implementors. + +#### signature + +REQUIRED. The `signature` parameter is a `Base64` encoded digital signature +generated by the client. The client uses the `algorithm` and `headers` request +parameters to form a canonicalized `signing string`. This `signing string` is +then signed with the key associated with `keyId` and the algorithm +corresponding to `algorithm`. The `signature` parameter is then set to the +`Base64` encoding of the signature. + +### Signing String Composition + +In order to generate the string that is signed with a key, the client MUST take +the values of each HTTP header specified by `headers` in the order they appear. + +1. If the header name is not `request-line` then append the lowercased header + name followed with an ASCII colon `:` and an ASCII space ` `. +2. If the header name is `request-line` then append the HTTP request line, + otherwise append the header value. +3. If value is not the last value then append an ASCII newline `\n`. The string + MUST NOT include a trailing ASCII newline. + +# Example Requests + +All requests refer to the following request (body omitted): + + POST /foo HTTP/1.1 + Host: example.org + Date: Tue, 07 Jun 2014 20:51:35 GMT + Content-Type: application/json + Digest: SHA-256=X48E9qOokqqrvdts8nOJRJN3OWDUoyWxBf7kbu9DBPE= + Content-Length: 18 + +The "rsa-key-1" keyId refers to a private key known to the client and a public +key known to the server.

Sending the default +scheme over a non-secure transport will leave the request vulnerable to +spoofing, tampering, replay/repudiation, and integrity violations (if using the +STRIDE threat-modeling methodology). + +## Insecure Transports + +If sending the request over plain HTTP, service providers SHOULD require clients +to sign ALL HTTP headers, and the `request-line`. Additionally, service +providers SHOULD require `Content-MD5` calculations to be performed to ensure +against any tampering from clients. + +## Nonces + +Nonces are out of scope for this document simply because many service providers +fail to implement them correctly, or do not adopt security specifications +because of the infrastructure complexity. Given the `header` parameterization, +a service provider is fully enabled to add nonce semantics into this scheme by +using something like an `x-request-nonce` header, and ensuring it is signed +with the `Date` header. + +## Clock Skew + +As the default scheme is to sign the `Date` header, service providers SHOULD +protect against logged replay attacks by enforcing a clock skew. The server +SHOULD be synchronized with NTP, and the recommendation in this specification +is to allow 300s of clock skew (in either direction). + +## Required Headers to Sign + +It is out of scope for this document to dictate what headers a service provider +will want to enforce, but service providers SHOULD at minimum include the +`Date` header. + +# References + +## Normative References + +* [RFC2616] Hypertext Transfer Protocol -- HTTP/1.1 +* [RFC2617] HTTP Authentication: Basic and Digest Access Authentication +* [RFC5246] The Transport Layer Security (TLS) Protocol Version 1.2 + +## Informative References + + Name: Mark Cavage (editor) + Company: Joyent, Inc. + Email: mark.cavage@joyent.com + URI: http://www.joyent.com + +# Appendix A - Test Values + +The following test data uses the RSA (1024b) keys, which we will refer +to as `keyId=Test` in the following samples: + + -----BEGIN PUBLIC KEY----- + MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDCFENGw33yGihy92pDjZQhl0C3 + 6rPJj+CvfSC8+q28hxA161QFNUd13wuCTUcq0Qd2qsBe/2hFyc2DCJJg0h1L78+6 + Z4UMR7EOcpfdUE9Hf3m/hs+FUR45uBJeDK1HSFHD8bHKD6kv8FPGfJTotc+2xjJw + oYi+1hqp1fIekaxsyQIDAQAB + -----END PUBLIC KEY----- + + -----BEGIN RSA PRIVATE KEY----- + MIICXgIBAAKBgQDCFENGw33yGihy92pDjZQhl0C36rPJj+CvfSC8+q28hxA161QF + NUd13wuCTUcq0Qd2qsBe/2hFyc2DCJJg0h1L78+6Z4UMR7EOcpfdUE9Hf3m/hs+F + UR45uBJeDK1HSFHD8bHKD6kv8FPGfJTotc+2xjJwoYi+1hqp1fIekaxsyQIDAQAB + AoGBAJR8ZkCUvx5kzv+utdl7T5MnordT1TvoXXJGXK7ZZ+UuvMNUCdN2QPc4sBiA + QWvLw1cSKt5DsKZ8UETpYPy8pPYnnDEz2dDYiaew9+xEpubyeW2oH4Zx71wqBtOK + kqwrXa/pzdpiucRRjk6vE6YY7EBBs/g7uanVpGibOVAEsqH1AkEA7DkjVH28WDUg + f1nqvfn2Kj6CT7nIcE3jGJsZZ7zlZmBmHFDONMLUrXR/Zm3pR5m0tCmBqa5RK95u + 412jt1dPIwJBANJT3v8pnkth48bQo/fKel6uEYyboRtA5/uHuHkZ6FQF7OUkGogc + mSJluOdc5t6hI1VsLn0QZEjQZMEOWr+wKSMCQQCC4kXJEsHAve77oP6HtG/IiEn7 + kpyUXRNvFsDE0czpJJBvL/aRFUJxuRK91jhjC68sA7NsKMGg5OXb5I5Jj36xAkEA + gIT7aFOYBFwGgQAQkWNKLvySgKbAZRTeLBacpHMuQdl1DfdntvAyqpAZ0lY0RKmW + G6aFKaqQfOXKCyWoUiVknQJAXrlgySFci/2ueKlIE1QqIiLSZ8V8OlpFLRnb1pzI + 7U1yQXnTAEFYM560yJlzUpOb1V4cScGd365tiSMvxLOvTA== + -----END RSA PRIVATE KEY----- + +And all examples use this request: + + + + POST /foo?param=value&pet=dog HTTP/1.1 + Host: example.com + Date: Thu, 05 Jan 2014 21:31:40 GMT + Content-Type: application/json + Digest: SHA-256=X48E9qOokqqrvdts8nOJRJN3OWDUoyWxBf7kbu9DBPE= + Content-Length: 18 + + {"hello": "world"} + + + +### Default + +The string to sign would be: + + + + + date: Thu, 05 Jan 2014 21:31:40 GMT + + + +The Authorization header would be: + + + + Authorization: Signature keyId="Test",algorithm="rsa-sha256",headers="date",signature="jKyvPcxB4JbmYY4mByyBY7cZfNl4OW9HpFQlG7N4YcJPteKTu4MWCLyk+gIr0wDgqtLWf9NLpMAMimdfsH7FSWGfbMFSrsVTHNTk0rK3usrfFnti1dxsM4jl0kYJCKTGI/UWkqiaxwNiKqGcdlEDrTcUhhsFsOIo8VhddmZTZ8w=" + + + +### All Headers + +Parameterized to include all headers, the string to sign would be (`+ "\n"` +inserted for readability): + + + + + (request-target): post /foo?param=value&pet=dog + host: example.com + date: Thu, 05 Jan 2014 21:31:40 GMT + content-type: application/json + digest: SHA-256=X48E9qOokqqrvdts8nOJRJN3OWDUoyWxBf7kbu9DBPE= + content-length: 18 + + + +The Authorization header would be: + + + + Authorization: Signature keyId="Test",algorithm="rsa-sha256",headers="(request-target) host date content-type digest content-length",signature="Ef7MlxLXoBovhil3AlyjtBwAL9g4TN3tibLj7uuNB3CROat/9KaeQ4hW2NiJ+pZ6HQEOx9vYZAyi+7cmIkmJszJCut5kQLAwuX+Ms/mUFvpKlSo9StS2bMXDBNjOh4Auj774GFj4gwjS+3NhFeoqyr/MuN6HsEnkvn6zdgfE2i0=" + + + +## Generating and verifying signatures using `openssl` + +The `openssl` commandline tool can be used to generate or verify the signatures listed above. + +Compose the signing string as usual, and pipe it into the the `openssl dgst` command, then into `openssl enc -base64`, as follows: + + $ printf 'date: Thu, 05 Jan 2014 21:31:40 GMT' | \ + openssl dgst -binary -sign /path/to/private.pem -sha256 | \ + openssl enc -base64 + jKyvPcxB4JbmYY4mByyBY7cZfNl4OW9Hp... + $ + +The `-sha256` option is necessary to produce an `rsa-sha256` signature.

+ + JSON (JavaScript Object Notation) Schema is a JSON media type for defining + the structure of JSON data. JSON Schema provides a contract for what JSON + data is required for a given application and how to interact with it. JSON + Schema is intended to define validation, documentation, hyperlink + navigation, and interaction control of JSON data. + +
+ +
+ + + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", + "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be + interpreted as described in RFC 2119. + +
+ + + +
+ + JSON Schema defines the media type "application/schema+json" for + describing the structure of other + JSON documents. JSON Schema is JSON-based and includes facilities + for describing the structure of JSON documents in terms of + allowable values, descriptions, and interpreting relations with other resources. + + + JSON Schema format is organized into several separate definitions. The first + definition is the core schema specification. This definition is primary + concerned with describing a JSON structure and specifying valid elements + in the structure. The second definition is the Hyper Schema specification + which is intended define elements in a structure that can be interpreted as + hyperlinks. + Hyper Schema builds on JSON Schema to describe the hyperlink structure of + other JSON documents and elements of interaction. This allows user agents to be able to successfully navigate + JSON documents based on their schemas. + + + Cumulatively JSON Schema acts as a meta-document that can be used to define the required type and constraints on + property values, as well as define the meaning of the property values + for the purpose of describing a resource and determining hyperlinks + within the representation. + +
+ An example JSON Schema that describes products might look like: + + + + + This schema defines the properties of the instance JSON documents, + the required properties (id, name, and price), as well as an optional + property (tags). This also defines the link relations of the instance + JSON documents. + +
+ +
+ + For this specification, schema will be used to denote a JSON Schema + definition, and an instance refers to a JSON value that the schema + will be describing and validating. + +
+ +
+ + The JSON Schema media type does not attempt to dictate the structure of JSON + representations that contain data, but rather provides a separate format + for flexibly communicating how a JSON representation should be + interpreted and validated, such that user agents can properly understand + acceptable structures and extrapolate hyperlink information + with the JSON document. It is acknowledged that JSON documents come + in a variety of structures, and JSON is unique in that the structure + of stored data structures often prescribes a non-ambiguous definite + JSON representation. Attempting to force a specific structure is generally + not viable, and therefore JSON Schema allows for a great flexibility + in the structure of the JSON data that it describes. + + + This specification is protocol agnostic. + The underlying protocol (such as HTTP) should sufficiently define the + semantics of the client-server interface, the retrieval of resource + representations linked to by JSON representations, and modification of + those resources. The goal of this + format is to sufficiently describe JSON structures such that one can + utilize existing information available in existing JSON + representations from a large variety of services that leverage a representational state transfer + architecture using existing protocols. + +
+
+ +
+ + JSON Schema instances are correlated to their schema by the "describedby" + relation, where the schema is defined to be the target of the relation. + Instance representations may be of the "application/json" media type or + any other subtype. Consequently, dictating how an instance + representation should specify the relation to the schema is beyond the normative scope + of this document (since this document specifically defines the JSON + Schema media type, and no other), but it is recommended that instances + specify their schema so that user agents can interpret the instance + representation and messages may retain the self-descriptive + characteristic, avoiding the need for out-of-band information about + instance data. Two approaches are recommended for declaring the + relation to the schema that describes the meaning of a JSON instance's (or collection + of instances) structure. A MIME type parameter named + "profile" or a relation of "describedby" (which could be defined by a Link header) may be used: + +
+ + + +
+ + or if the content is being transferred by a protocol (such as HTTP) that + provides headers, a Link header can be used: + +
+ +; rel="describedby" +]]> + +
+ + Instances MAY specify multiple schemas, to indicate all the schemas that + are applicable to the data, and the data SHOULD be valid by all the schemas. + The instance data MAY have multiple schemas + that it is defined by (the instance data SHOULD be valid for those schemas). + Or if the document is a collection of instances, the collection MAY contain + instances from different schemas. When collections contain heterogeneous + instances, the "pathStart" attribute MAY be specified in the + schema to disambiguate which schema should be applied for each item in the + collection. However, ultimately, the mechanism for referencing a schema is up to the + media type of the instance documents (if they choose to specify that schemas + can be referenced). + + +
+ + JSON Schemas can themselves be described using JSON Schemas. + A self-describing JSON Schema for the core JSON Schema can + be found at http://json-schema.org/schema for the latest version or + http://json-schema.org/draft-03/schema for the draft-03 version. The hyper schema + self-description can be found at http://json-schema.org/hyper-schema + or http://json-schema.org/draft-03/hyper-schema. All schemas + used within a protocol with media type definitions + SHOULD include a MIME parameter that refers to the self-descriptive + hyper schema or another schema that extends this hyper schema: + +
+ + + +
+ +
+
+ +
+ + A JSON Schema is a JSON Object that defines various attributes + (including usage and valid values) of a JSON value. JSON + Schema has recursive capabilities; there are a number of elements + in the structure that allow for nested JSON Schemas. + + +
+ An example JSON Schema definition could look like: + + + +
+ + + A JSON Schema object may have any of the following properties, called schema + attributes (all attributes are optional): + + +
+ + This attribute defines what the primitive type or the schema of the instance MUST be in order to validate. + This attribute can take one of two forms: + + + + A string indicating a primitive or simple type. The following are acceptable string values: + + + Value MUST be a string. + Value MUST be a number, floating point numbers are allowed. + Value MUST be an integer, no floating point numbers are allowed. This is a subset of the number type. + Value MUST be a boolean. + Value MUST be an object. + Value MUST be an array. + Value MUST be null. Note this is mainly for purpose of being able use union types to define nullability. If this type is not included in a union, null values are not allowed (the primitives listed above do not allow nulls on their own). + Value MAY be of any type including null. + + + If the property is not defined or is not in this list, then any type of value is acceptable. + Other type values MAY be used for custom purposes, but minimal validators of the specification + implementation can allow any instance value on unknown type values. + + + + An array of two or more simple type definitions. Each item in the array MUST be a simple type definition or a schema. + The instance value is valid if it is of the same type as one of the simple type definitions, or valid by one of the schemas, in the array. + + + + +
+ For example, a schema that defines if an instance can be a string or a number would be: + + +
+
+ +
+ This attribute is an object with property definitions that define the valid values of instance object property values. When the instance value is an object, the property values of the instance object MUST conform to the property definitions in this object. In this object, each property definition's value MUST be a schema, and the property's name MUST be the name of the instance property that it defines. The instance property value MUST be valid according to the schema from the property definition. Properties are considered unordered, the order of the instance properties MAY be in any order. +
+ +
+ This attribute is an object that defines the schema for a set of property names of an object instance. The name of each property of this attribute's object is a regular expression pattern in the ECMA 262/Perl 5 format, while the value is a schema. If the pattern matches the name of a property on the instance object, the value of the instance's property MUST be valid against the pattern name's schema value. +
+ +
+ This attribute defines a schema for all properties that are not explicitly defined in an object type definition. If specified, the value MUST be a schema or a boolean. If false is provided, no additional properties are allowed beyond the properties defined in the schema. The default value is an empty schema which allows any value for additional properties. +
+ +
+ This attribute defines the allowed items in an instance array, and MUST be a schema or an array of schemas. The default value is an empty schema which allows any value for items in the instance array. + When this attribute value is a schema and the instance value is an array, then all the items in the array MUST be valid according to the schema. + When this attribute value is an array of schemas and the instance value is an array, each position in the instance array MUST conform to the schema in the corresponding position for this array. This called tuple typing. When tuple typing is used, additional items are allowed, disallowed, or constrained by the "additionalItems" attribute using the same rules as "additionalProperties" for objects. +
+ +
+ This provides a definition for additional items in an array instance when tuple definitions of the items is provided. This can be false to indicate additional items in the array are not allowed, or it can be a schema that defines the schema of the additional items. +
+ +
+ This attribute indicates if the instance must have a value, and not be undefined. This is false by default, making the instance optional. +
+ +
+ This attribute is an object that defines the requirements of a property on an instance object. If an object instance has a property with the same name as a property in this attribute's object, then the instance must be valid against the attribute's property value (hereafter referred to as the "dependency value"). + + The dependency value can take one of two forms: + + + + If the dependency value is a string, then the instance object MUST have a property with the same name as the dependency value. + If the dependency value is an array of strings, then the instance object MUST have a property with the same name as each string in the dependency value's array. + + + If the dependency value is a schema, then the instance object MUST be valid against the schema. + + + +
+ +
+ This attribute defines the minimum value of the instance property when the type of the instance value is a number. +
+ +
+ This attribute defines the maximum value of the instance property when the type of the instance value is a number. +
+ +
+ This attribute indicates if the value of the instance (if the instance is a number) can not equal the number defined by the "minimum" attribute. This is false by default, meaning the instance value can be greater then or equal to the minimum value. +
+ +
+ This attribute indicates if the value of the instance (if the instance is a number) can not equal the number defined by the "maximum" attribute. This is false by default, meaning the instance value can be less then or equal to the maximum value. +
+ +
+ This attribute defines the minimum number of values in an array when the array is the instance value. +
+ +
+ This attribute defines the maximum number of values in an array when the array is the instance value. +
+ +
+ This attribute indicates that all items in an array instance MUST be unique (contains no two identical values). + + Two instance are consider equal if they are both of the same type and: + + + are null; or + are booleans/numbers/strings and have the same value; or + are arrays, contains the same number of items, and each item in the array is equal to the corresponding item in the other array; or + are objects, contains the same property names, and each property in the object is equal to the corresponding property in the other object. + + +
+ +
+ When the instance value is a string, this provides a regular expression that a string instance MUST match in order to be valid. Regular expressions SHOULD follow the regular expression specification from ECMA 262/Perl 5 +
+ +
+ When the instance value is a string, this defines the minimum length of the string. +
+ +
+ When the instance value is a string, this defines the maximum length of the string. +
+ +
+ This provides an enumeration of all possible values that are valid for the instance property. This MUST be an array, and each item in the array represents a possible value for the instance value. If this attribute is defined, the instance value MUST be one of the values in the array in order for the schema to be valid. Comparison of enum values uses the same algorithm as defined in "uniqueItems". +
+ +
+ This attribute defines the default value of the instance when the instance is undefined. +
+ +
+ This attribute is a string that provides a short description of the instance property. +
+ +
+ This attribute is a string that provides a full description of the of purpose the instance property. +
+ +
+ This property defines the type of data, content type, or microformat to be expected in the instance property values. A format attribute MAY be one of the values listed below, and if so, SHOULD adhere to the semantics describing for the format. A format SHOULD only be used to give meaning to primitive types (string, integer, number, or boolean). Validators MAY (but are not required to) validate that the instance values conform to a format. + + + The following formats are predefined: + + + This SHOULD be a date in ISO 8601 format of YYYY-MM-DDThh:mm:ssZ in UTC time. This is the recommended form of date/timestamp. + This SHOULD be a date in the format of YYYY-MM-DD. It is recommended that you use the "date-time" format instead of "date" unless you need to transfer only the date part. + This SHOULD be a time in the format of hh:mm:ss. It is recommended that you use the "date-time" format instead of "time" unless you need to transfer only the time part. + This SHOULD be the difference, measured in milliseconds, between the specified time and midnight, 00:00 of January 1, 1970 UTC. The value SHOULD be a number (integer or float). + A regular expression, following the regular expression specification from ECMA 262/Perl 5. + This is a CSS color (like "#FF0000" or "red"), based on CSS 2.1. + This is a CSS style definition (like "color: red; background-color:#FFF"), based on CSS 2.1. + This SHOULD be a phone number (format MAY follow E.123). + This value SHOULD be a URI. + This SHOULD be an email address. + This SHOULD be an ip version 4 address. + This SHOULD be an ip version 6 address. + This SHOULD be a host-name. + + + + Additional custom formats MAY be created. These custom formats MAY be expressed as an URI, and this URI MAY reference a schema of that format. +
+ +
+ This attribute defines what value the number instance must be divisible by with no remainder (the result of the division must be an integer.) The value of this attribute SHOULD NOT be 0. +
+ +
+ This attribute takes the same values as the "type" attribute, however if the instance matches the type or if this value is an array and the instance matches any type or schema in the array, then this instance is not valid. +
+ +
+ The value of this property MUST be another schema which will provide a base schema which the current schema will inherit from. The inheritance rules are such that any instance that is valid according to the current schema MUST be valid according to the referenced schema. This MAY also be an array, in which case, the instance MUST be valid for all the schemas in the array. A schema that extends another schema MAY define additional attributes, constrain existing attributes, or add other constraints. + + Conceptually, the behavior of extends can be seen as validating an + instance against all constraints in the extending schema as well as + the extended schema(s). More optimized implementations that merge + schemas are possible, but are not required. Some examples of using "extends": + +
+ + + +
+ +
+ + + +
+ +
+ +
+ + This attribute defines the current URI of this schema (this attribute is + effectively a "self" link). This URI MAY be relative or absolute. If + the URI is relative it is resolved against the current URI of the parent + schema it is contained in. If this schema is not contained in any + parent schema, the current URI of the parent schema is held to be the + URI under which this schema was addressed. If id is missing, the current URI of a schema is + defined to be that of the parent schema. The current URI of the schema + is also used to construct relative references such as for $ref. + +
+ +
+ + This attribute defines a URI of a schema that contains the full representation of this schema. + When a validator encounters this attribute, it SHOULD replace the current schema with the schema referenced by the value's URI (if known and available) and re-validate the instance. + This URI MAY be relative or absolute, and relative URIs SHOULD be resolved against the URI of the current schema. + +
+ +
+ + This attribute defines a URI of a JSON Schema that is the schema of the current schema. + When this attribute is defined, a validator SHOULD use the schema referenced by the value's URI (if known and available) when resolving Hyper Schemalinks. + + + + A validator MAY use this attribute's value to determine which version of JSON Schema the current schema is written in, and provide the appropriate validation features and behavior. + Therefore, it is RECOMMENDED that all schema authors include this attribute in their schemas to prevent conflicts with future JSON Schema specification changes. + +
+
+ +
+ + The following attributes are specified in addition to those + attributes that already provided by the core schema with the specific + purpose of informing user agents of relations between resources based + on JSON data. Just as with JSON + schema attributes, all the attributes in hyper schemas are optional. + Therefore, an empty object is a valid (non-informative) schema, and + essentially describes plain JSON (no constraints on the structures). + Addition of attributes provides additive information for user agents. + + +
+ + The value of the links property MUST be an array, where each item + in the array is a link description object which describes the link + relations of the instances. + + +
+ + A link description object is used to describe link relations. In + the context of a schema, it defines the link relations of the + instances of the schema, and can be parameterized by the instance + values. The link description format can be used on its own in + regular (non-schema documents), and use of this format can + be declared by referencing the normative link description + schema as the the schema for the data structure that uses the + links. The URI of the normative link description schema is: + http://json-schema.org/links (latest version) or + http://json-schema.org/draft-03/links (draft-03 version). + + +
+ + The value of the "href" link description property + indicates the target URI of the related resource. The value + of the instance property SHOULD be resolved as a URI-Reference per RFC 3986 + and MAY be a relative URI. The base URI to be used for relative resolution + SHOULD be the URI used to retrieve the instance object (not the schema) + when used within a schema. Also, when links are used within a schema, the URI + SHOULD be parametrized by the property values of the instance + object, if property values exist for the corresponding variables + in the template (otherwise they MAY be provided from alternate sources, like user input). + + + + Instance property values SHOULD be substituted into the URIs where + matching braces ('{', '}') are found surrounding zero or more characters, + creating an expanded URI. Instance property value substitutions are resolved + by using the text between the braces to denote the property name + from the instance to get the value to substitute. + +
+ For example, if an href value is defined: + + + + Then it would be resolved by replace the value of the "id" property value from the instance object. +
+ +
+ If the value of the "id" property was "45", the expanded URI would be: + + + +
+ + If matching braces are found with the string "@" (no quotes) between the braces, then the + actual instance value SHOULD be used to replace the braces, rather than a property value. + This should only be used in situations where the instance is a scalar (string, + boolean, or number), and not for objects or arrays. + +
+ +
+ + The value of the "rel" property indicates the name of the + relation to the target resource. The relation to the target SHOULD be interpreted as specifically from the instance object that the schema (or sub-schema) applies to, not just the top level resource that contains the object within its hierarchy. If a resource JSON representation contains a sub object with a property interpreted as a link, that sub-object holds the relation with the target. A relation to target from the top level resource MUST be indicated with the schema describing the top level JSON representation. + + + + Relationship definitions SHOULD NOT be media type dependent, and users are encouraged to utilize existing accepted relation definitions, including those in existing relation registries (see RFC 4287). However, we define these relations here for clarity of normative interpretation within the context of JSON hyper schema defined relations: + + + + If the relation value is "self", when this property is encountered in + the instance object, the object represents a resource and the instance object is + treated as a full representation of the target resource identified by + the specified URI. + + + + This indicates that the target of the link is the full representation for the instance object. The object that contains this link possibly may not be the full representation. + + + + This indicates the target of the link is the schema for the instance object. This MAY be used to specifically denote the schemas of objects within a JSON object hierarchy, facilitating polymorphic type data structures. + + + + This relation indicates that the target of the link + SHOULD be treated as the root or the body of the representation for the + purposes of user agent interaction or fragment resolution. All other + properties of the instance objects can be regarded as meta-data + descriptions for the data. + + + + + + The following relations are applicable for schemas (the schema as the "from" resource in the relation): + + + This indicates the target resource that represents collection of instances of a schema. + This indicates a target to use for creating new instances of a schema. This link definition SHOULD be a submission link with a non-safe method (like POST). + + + + +
+ For example, if a schema is defined: + + + +
+ +
+ And if a collection of instance resource's JSON representation was retrieved: + + + +
+ + This would indicate that for the first item in the collection, its own + (self) URI would resolve to "/Resource/thing" and the first item's "up" + relation SHOULD be resolved to the resource at "/Resource/parent". + The "children" collection would be located at "/Resource/?upId=thing". + +
+ +
+ This property value is a schema that defines the expected structure of the JSON representation of the target of the link. +
+ +
+ + The following properties also apply to link definition objects, and + provide functionality analogous to HTML forms, in providing a + means for submitting extra (often user supplied) information to send to a server. + + +
+ + This attribute defines which method can be used to access the target resource. + In an HTTP environment, this would be "GET" or "POST" (other HTTP methods + such as "PUT" and "DELETE" have semantics that are clearly implied by + accessed resources, and do not need to be defined here). + This defaults to "GET". + +
+ +
+ + If present, this property indicates a query media type format that the server + supports for querying or posting to the collection of instances at the target + resource. The query can be + suffixed to the target URI to query the collection with + property-based constraints on the resources that SHOULD be returned from + the server or used to post data to the resource (depending on the method). + +
+ For example, with the following schema: + + + + This indicates that the client can query the server for instances that have a specific name. +
+ +
+ For example: + + + +
+ + If no enctype or method is specified, only the single URI specified by + the href property is defined. If the method is POST, "application/json" is + the default media type. + +
+ +
+ + This attribute contains a schema which defines the acceptable structure of the submitted + request (for a GET request, this schema would define the properties for the query string + and for a POST request, this would define the body). + +
+
+
+
+ +
+ + This property indicates the fragment resolution protocol to use for + resolving fragment identifiers in URIs within the instance + representations. This applies to the instance object URIs and all + children of the instance object's URIs. The default fragment resolution + protocol is "slash-delimited", which is defined below. Other fragment + resolution protocols MAY be used, but are not defined in this document. + + + + The fragment identifier is based on RFC 2396, Sec 5, and defines the + mechanism for resolving references to entities within a document. + + +
+ + With the slash-delimited fragment resolution protocol, the fragment + identifier is interpreted as a series of property reference tokens that start with and + are delimited by the "/" character (\x2F). Each property reference token + is a series of unreserved or escaped URI characters. Each property + reference token SHOULD be interpreted, starting from the beginning of + the fragment identifier, as a path reference in the target JSON + structure. The final target value of the fragment can be determined by + starting with the root of the JSON structure from the representation of + the resource identified by the pre-fragment URI. If the target is a JSON + object, then the new target is the value of the property with the name + identified by the next property reference token in the fragment. If the + target is a JSON array, then the target is determined by finding the + item in array the array with the index defined by the next property + reference token (which MUST be a number). The target is successively + updated for each property reference token, until the entire fragment has + been traversed. + + + + Property names SHOULD be URI-encoded. In particular, any "/" in a + property name MUST be encoded to avoid being interpreted as a property + delimiter. + + + +
+ For example, for the following JSON representation: + + + +
+ +
+ The following fragment identifiers would be resolved: + + + +
+ +
+ +
+ + The dot-delimited fragment resolution protocol is the same as + slash-delimited fragment resolution protocol except that the "." character + (\x2E) is used as the delimiter between property names (instead of "/") and + the path does not need to start with a ".". For example, #.foo and #foo are a valid fragment + identifiers for referencing the value of the foo propery. + +
+
+ +
+ This attribute indicates that the instance property SHOULD NOT be changed. Attempts by a user agent to modify the value of this property are expected to be rejected by a server. +
+ +
+ If the instance property value is a string, this attribute defines that the string SHOULD be interpreted as binary data and decoded using the encoding named by this schema property. RFC 2045, Sec 6.1 lists the possible values for this property. +
+ +
+ + This attribute is a URI that defines what the instance's URI MUST start with in order to validate. + The value of the "pathStart" attribute MUST be resolved as per RFC 3986, Sec 5, + and is relative to the instance's URI. + + + + When multiple schemas have been referenced for an instance, the user agent + can determine if this schema is applicable for a particular instance by + determining if the URI of the instance begins with the the value of the "pathStart" + attribute. If the URI of the instance does not start with this URI, + or if another schema specifies a starting URI that is longer and also matches the + instance, this schema SHOULD NOT be applied to the instance. Any schema + that does not have a pathStart attribute SHOULD be considered applicable + to all the instances for which it is referenced. + +
+ +
+ This attribute defines the media type of the instance representations that this schema is defining. +
+
+ +
+ + This specification is a sub-type of the JSON format, and + consequently the security considerations are generally the same as RFC 4627. + However, an additional issue is that when link relation of "self" + is used to denote a full representation of an object, the user agent + SHOULD NOT consider the representation to be the authoritative representation + of the resource denoted by the target URI if the target URI is not + equivalent to or a sub-path of the the URI used to request the resource + representation which contains the target URI with the "self" link. + +
+ For example, if a hyper schema was defined: + + + +
+ +
+ And a resource was requested from somesite.com: + + + +
+ +
+ With a response of: + + + +
+ +
+ +
+ The proposed MIME media type for JSON Schema is "application/schema+json". + Type name: application + Subtype name: schema+json + Required parameters: profile + + The value of the profile parameter SHOULD be a URI (relative or absolute) that + refers to the schema used to define the structure of this structure (the + meta-schema). Normally the value would be http://json-schema.org/draft-03/hyper-schema, + but it is allowable to use other schemas that extend the hyper schema's meta- + schema. + + Optional parameters: pretty + The value of the pretty parameter MAY be true or false to indicate if additional whitespace has been included to make the JSON representation easier to read. + +
+ + This registry is maintained by IANA per RFC 4287 and this specification adds + four values: "full", "create", "instances", "root". New + assignments are subject to IESG Approval, as outlined in RFC 5226. + Requests should be made by email to IANA, which will then forward the + request to the IESG, requesting approval. + +

+ + JSON (JavaScript Object Notation) Schema is a JSON media type for defining + the structure of JSON data. JSON Schema provides a contract for what JSON + data is required for a given application and how to interact with it. JSON + Schema is intended to define validation, documentation, hyperlink + navigation, and interaction control of JSON data. + +
+ +
+ + + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", + "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be + interpreted as described in RFC 2119. + + + + The terms "JSON", "JSON text", "JSON value", "member", "element", "object", + "array", "number", "string", "boolean", "true", "false", and "null" in this + document are to be interpreted as defined in RFC 4627. + + + + This specification also uses the following defined terms: + + + A JSON Schema object. + Equivalent to "JSON value" as defined in RFC 4627. + Equivalent to "member" as defined in RFC 4627. + Equivalent to "element" as defined in RFC 4627. + A property of a JSON Schema object. + + +
+ +
+ + JSON Schema defines the media type "application/schema+json" for + describing the structure of JSON text. JSON Schemas are also written in JSON and includes facilities + for describing the structure of JSON in terms of + allowable values, descriptions, and interpreting relations with other resources. + + + This document is organized into several separate definitions. The first + definition is the core schema specification. This definition is primary + concerned with describing a JSON structure and specifying valid elements + in the structure. The second definition is the Hyper Schema specification + which is intended to define elements in a structure that can be interpreted as + hyperlinks. + Hyper Schema builds on JSON Schema to describe the hyperlink structure of + JSON values. This allows user agents to be able to successfully navigate + documents containing JSON based on their schemas. + + + Cumulatively JSON Schema acts as meta-JSON that can be used to define the + required type and constraints on JSON values, as well as define the meaning + of the JSON values for the purpose of describing a resource and determining + hyperlinks within the representation. + +
+ An example JSON Schema that describes products might look like: + + + + + This schema defines the properties of the instance, + the required properties (id, name, and price), as well as an optional + property (tags). This also defines the link relations of the instance. + +
+ +
+ + The JSON Schema media type does not attempt to dictate the structure of JSON + values that contain data, but rather provides a separate format + for flexibly communicating how a JSON value should be + interpreted and validated, such that user agents can properly understand + acceptable structures and extrapolate hyperlink information + from the JSON. It is acknowledged that JSON values come + in a variety of structures, and JSON is unique in that the structure + of stored data structures often prescribes a non-ambiguous definite + JSON representation. Attempting to force a specific structure is generally + not viable, and therefore JSON Schema allows for a great flexibility + in the structure of the JSON data that it describes. + + + This specification is protocol agnostic. + The underlying protocol (such as HTTP) should sufficiently define the + semantics of the client-server interface, the retrieval of resource + representations linked to by JSON representations, and modification of + those resources. The goal of this + format is to sufficiently describe JSON structures such that one can + utilize existing information available in existing JSON + representations from a large variety of services that leverage a representational state transfer + architecture using existing protocols. + +
+
+ +
+ + JSON values are correlated to their schema by the "describedby" + relation, where the schema is the target of the relation. + JSON values MUST be of the "application/json" media type or + any other subtype. Consequently, dictating how a JSON value should + specify the relation to the schema is beyond the normative scope + of this document since this document specifically defines the JSON + Schema media type, and no other. It is RECOMMNENDED that JSON values + specify their schema so that user agents can interpret the instance + and retain the self-descriptive characteristics. This avoides the need for out-of-band information about + instance data. Two approaches are recommended for declaring the + relation to the schema that describes the meaning of a JSON instance's (or collection + of instances) structure. A MIME type parameter named + "profile" or a relation of "describedby" (which could be specified by a Link header) may be used: + +
+ + + +
+ + or if the content is being transferred by a protocol (such as HTTP) that + provides headers, a Link header can be used: + +
+ +; rel="describedby" +]]> + +
+ + Instances MAY specify multiple schemas, to indicate all the schemas that + are applicable to the data, and the data SHOULD be valid by all the schemas. + The instance data MAY have multiple schemas + that it is described by (the instance data SHOULD be valid for those schemas). + Or if the document is a collection of instances, the collection MAY contain + instances from different schemas. The mechanism for referencing a schema is + determined by the media type of the instance (if it provides a method for + referencing schemas). + + +
+ + JSON Schemas can themselves be described using JSON Schemas. + A self-describing JSON Schema for the core JSON Schema can + be found at http://json-schema.org/schema for the latest version or + http://json-schema.org/draft-04/schema for the draft-04 version. The hyper schema + self-description can be found at http://json-schema.org/hyper-schema + or http://json-schema.org/draft-04/hyper-schema. All schemas + used within a protocol with a media type specified SHOULD include a MIME parameter that refers to the self-descriptive + hyper schema or another schema that extends this hyper schema: + +
+ + + +
+ +
+
+ +
+ + A JSON Schema is a JSON object that defines various attributes + (including usage and valid values) of a JSON value. JSON + Schema has recursive capabilities; there are a number of elements + in the structure that allow for nested JSON Schemas. + + +
+ An example JSON Schema could look like: + + + +
+ + + A JSON Schema object MAY have any of the following optional properties: + + + + + +
+ + This attribute defines what the primitive type or the schema of the instance MUST be in order to validate. + This attribute can take one of two forms: + + + + A string indicating a primitive or simple type. The string MUST be one of the following values: + + + Instance MUST be an object. + Instance MUST be an array. + Instance MUST be a string. + Instance MUST be a number, including floating point numbers. + Instance MUST be the JSON literal "true" or "false". + Instance MUST be the JSON literal "null". Note that without this type, null values are not allowed. + Instance MAY be of any type, including null. + + + + + An array of one or more simple or schema types. + The instance value is valid if it is of the same type as one of the simple types, or valid by one of the schemas, in the array. + + + + If this attribute is not specified, then all value types are accepted. + + +
+ For example, a schema that defines if an instance can be a string or a number would be: + + +
+
+ +
+ + This attribute is an object with properties that specify the schemas for the properties of the instance object. + In this attribute's object, each property value MUST be a schema. + When the instance value is an object, the value of the instance's properties MUST be valid according to the schemas with the same property names specified in this attribute. + Objects are unordered, so therefore the order of the instance properties or attribute properties MUST NOT determine validation success. + +
+ +
+ + This attribute is an object that defines the schema for a set of property names of an object instance. + The name of each property of this attribute's object is a regular expression pattern in the ECMA 262/Perl 5 format, while the value is a schema. + If the pattern matches the name of a property on the instance object, the value of the instance's property MUST be valid against the pattern name's schema value. + +
+ +
+ This attribute specifies how any instance property that is not explicitly defined by either the "properties" or "patternProperties" attributes (hereafter referred to as "additional properties") is handled. If specified, the value MUST be a schema or a boolean. + If a schema is provided, then all additional properties MUST be valid according to the schema. + If false is provided, then no additional properties are allowed. + The default value is an empty schema, which allows any value for additional properties. +
+ +
+ This attribute provides the allowed items in an array instance. If specified, this attribute MUST be a schema or an array of schemas. + When this attribute value is a schema and the instance value is an array, then all the items in the array MUST be valid according to the schema. + When this attribute value is an array of schemas and the instance value is an array, each position in the instance array MUST be valid according to the schema in the corresponding position for this array. This called tuple typing. When tuple typing is used, additional items are allowed, disallowed, or constrained by the "additionalItems" attribute the same way as "additionalProperties" for objects is. +
+ +
+ This attribute specifies how any item in the array instance that is not explicitly defined by "items" (hereafter referred to as "additional items") is handled. If specified, the value MUST be a schema or a boolean. + If a schema is provided: + + If the "items" attribute is unspecified, then all items in the array instance must be valid against this schema. + If the "items" attribute is a schema, then this attribute is ignored. + If the "items" attribute is an array (during tuple typing), then any additional items MUST be valid against this schema. + + + If false is provided, then any additional items in the array are not allowed. + The default value is an empty schema, which allows any value for additional items. +
+ +
+ This attribute is an array of strings that defines all the property names that must exist on the object instance. +
+ +
+ This attribute is an object that specifies the requirements of a property on an object instance. If an object instance has a property with the same name as a property in this attribute's object, then the instance must be valid against the attribute's property value (hereafter referred to as the "dependency value"). + + The dependency value can take one of two forms: + + + + If the dependency value is a string, then the instance object MUST have a property with the same name as the dependency value. + If the dependency value is an array of strings, then the instance object MUST have a property with the same name as each string in the dependency value's array. + + + If the dependency value is a schema, then the instance object MUST be valid against the schema. + + + +
+ +
+ This attribute defines the minimum value of the instance property when the type of the instance value is a number. +
+ +
+ This attribute defines the maximum value of the instance property when the type of the instance value is a number. +
+ +
+ This attribute indicates if the value of the instance (if the instance is a number) can not equal the number defined by the "minimum" attribute. This is false by default, meaning the instance value can be greater then or equal to the minimum value. +
+ +
+ This attribute indicates if the value of the instance (if the instance is a number) can not equal the number defined by the "maximum" attribute. This is false by default, meaning the instance value can be less then or equal to the maximum value. +
+ +
+ This attribute defines the minimum number of values in an array when the array is the instance value. +
+ +
+ This attribute defines the maximum number of values in an array when the array is the instance value. +
+ +
+ This attribute defines the minimum number of properties required on an object instance. +
+ +
+ This attribute defines the maximum number of properties the object instance can have. +
+ +
+ This attribute indicates that all items in an array instance MUST be unique (contains no two identical values). + + Two instance are consider equal if they are both of the same type and: + + + are null; or + are booleans/numbers/strings and have the same value; or + are arrays, contains the same number of items, and each item in the array is equal to the item at the corresponding index in the other array; or + are objects, contains the same property names, and each property in the object is equal to the corresponding property in the other object. + + +
+ +
+ When the instance value is a string, this provides a regular expression that a string instance MUST match in order to be valid. Regular expressions SHOULD follow the regular expression specification from ECMA 262/Perl 5 +
+ +
+ When the instance value is a string, this defines the minimum length of the string. +
+ +
+ When the instance value is a string, this defines the maximum length of the string. +
+ +
+ This provides an enumeration of all possible values that are valid for the instance property. This MUST be an array, and each item in the array represents a possible value for the instance value. If this attribute is defined, the instance value MUST be one of the values in the array in order for the schema to be valid. Comparison of enum values uses the same algorithm as defined in "uniqueItems". +
+ +
+ This attribute defines the default value of the instance when the instance is undefined. +
+ +
+ This attribute is a string that provides a short description of the instance property. +
+ +
+ This attribute is a string that provides a full description of the of purpose the instance property. +
+ +
+ This attribute defines what value the number instance must be divisible by with no remainder (the result of the division must be an integer.) The value of this attribute SHOULD NOT be 0. +
+ +
+ This attribute takes the same values as the "type" attribute, however if the instance matches the type or if this value is an array and the instance matches any type or schema in the array, then this instance is not valid. +
+ +
+ The value of this property MUST be another schema which will provide a base schema which the current schema will inherit from. The inheritance rules are such that any instance that is valid according to the current schema MUST be valid according to the referenced schema. This MAY also be an array, in which case, the instance MUST be valid for all the schemas in the array. A schema that extends another schema MAY define additional attributes, constrain existing attributes, or add other constraints. + + Conceptually, the behavior of extends can be seen as validating an + instance against all constraints in the extending schema as well as + the extended schema(s). More optimized implementations that merge + schemas are possible, but are not required. Some examples of using "extends": + +
+ + + +
+ +
+ + + +
+ +
+ +
+ + This attribute defines the current URI of this schema (this attribute is + effectively a "self" link). This URI MAY be relative or absolute. If + the URI is relative it is resolved against the current URI of the parent + schema it is contained in. If this schema is not contained in any + parent schema, the current URI of the parent schema is held to be the + URI under which this schema was addressed. If id is missing, the current URI of a schema is + defined to be that of the parent schema. The current URI of the schema + is also used to construct relative references such as for $ref. + +
+ +
+ + This attribute defines a URI of a schema that contains the full representation of this schema. + When a validator encounters this attribute, it SHOULD replace the current schema with the schema referenced by the value's URI (if known and available) and re-validate the instance. + This URI MAY be relative or absolute, and relative URIs SHOULD be resolved against the URI of the current schema. + +
+ +
+ + This attribute defines a URI of a JSON Schema that is the schema of the current schema. + When this attribute is defined, a validator SHOULD use the schema referenced by the value's URI (if known and available) when resolving Hyper Schemalinks. + + + + A validator MAY use this attribute's value to determine which version of JSON Schema the current schema is written in, and provide the appropriate validation features and behavior. + Therefore, it is RECOMMENDED that all schema authors include this attribute in their schemas to prevent conflicts with future JSON Schema specification changes. + +
+
+ +
+ + The following attributes are specified in addition to those + attributes that already provided by the core schema with the specific + purpose of informing user agents of relations between resources based + on JSON data. Just as with JSON + schema attributes, all the attributes in hyper schemas are optional. + Therefore, an empty object is a valid (non-informative) schema, and + essentially describes plain JSON (no constraints on the structures). + Addition of attributes provides additive information for user agents. + + +
+ + The value of the links property MUST be an array, where each item + in the array is a link description object which describes the link + relations of the instances. + + + + +
+ + A link description object is used to describe link relations. In + the context of a schema, it defines the link relations of the + instances of the schema, and can be parameterized by the instance + values. The link description format can be used without JSON Schema, + and use of this format can + be declared by referencing the normative link description + schema as the the schema for the data structure that uses the + links. The URI of the normative link description schema is: + http://json-schema.org/links (latest version) or + http://json-schema.org/draft-04/links (draft-04 version). + + +
+ + The value of the "href" link description property + indicates the target URI of the related resource. The value + of the instance property SHOULD be resolved as a URI-Reference per RFC 3986 + and MAY be a relative URI. The base URI to be used for relative resolution + SHOULD be the URI used to retrieve the instance object (not the schema) + when used within a schema. Also, when links are used within a schema, the URI + SHOULD be parametrized by the property values of the instance + object, if property values exist for the corresponding variables + in the template (otherwise they MAY be provided from alternate sources, like user input). + + + + Instance property values SHOULD be substituted into the URIs where + matching braces ('{', '}') are found surrounding zero or more characters, + creating an expanded URI. Instance property value substitutions are resolved + by using the text between the braces to denote the property name + from the instance to get the value to substitute. + +
+ For example, if an href value is defined: + + + + Then it would be resolved by replace the value of the "id" property value from the instance object. +
+ +
+ If the value of the "id" property was "45", the expanded URI would be: + + + +
+ + If matching braces are found with the string "@" (no quotes) between the braces, then the + actual instance value SHOULD be used to replace the braces, rather than a property value. + This should only be used in situations where the instance is a scalar (string, + boolean, or number), and not for objects or arrays. + +
+ +
+ + The value of the "rel" property indicates the name of the + relation to the target resource. The relation to the target SHOULD be interpreted as specifically from the instance object that the schema (or sub-schema) applies to, not just the top level resource that contains the object within its hierarchy. If a resource JSON representation contains a sub object with a property interpreted as a link, that sub-object holds the relation with the target. A relation to target from the top level resource MUST be indicated with the schema describing the top level JSON representation. + + + + Relationship definitions SHOULD NOT be media type dependent, and users are encouraged to utilize existing accepted relation definitions, including those in existing relation registries (see RFC 4287). However, we define these relations here for clarity of normative interpretation within the context of JSON hyper schema defined relations: + + + + If the relation value is "self", when this property is encountered in + the instance object, the object represents a resource and the instance object is + treated as a full representation of the target resource identified by + the specified URI. + + + + This indicates that the target of the link is the full representation for the instance object. The object that contains this link possibly may not be the full representation. + + + + This indicates the target of the link is the schema for the instance object. This MAY be used to specifically denote the schemas of objects within a JSON object hierarchy, facilitating polymorphic type data structures. + + + + This relation indicates that the target of the link + SHOULD be treated as the root or the body of the representation for the + purposes of user agent interaction or fragment resolution. All other + properties of the instance objects can be regarded as meta-data + descriptions for the data. + + + + + + The following relations are applicable for schemas (the schema as the "from" resource in the relation): + + + This indicates the target resource that represents collection of instances of a schema. + This indicates a target to use for creating new instances of a schema. This link definition SHOULD be a submission link with a non-safe method (like POST). + + + + +
+ For example, if a schema is defined: + + + +
+ +
+ And if a collection of instance resource's JSON representation was retrieved: + + + +
+ + This would indicate that for the first item in the collection, its own + (self) URI would resolve to "/Resource/thing" and the first item's "up" + relation SHOULD be resolved to the resource at "/Resource/parent". + The "children" collection would be located at "/Resource/?upId=thing". + +
+ +
+ This property value is a string that defines the templating language used in the "href" attribute. If no templating language is defined, then the default Link Description Object templating langauge is used. +
+ +
+ This property value is a schema that defines the expected structure of the JSON representation of the target of the link. +
+ +
+ + The following properties also apply to link definition objects, and + provide functionality analogous to HTML forms, in providing a + means for submitting extra (often user supplied) information to send to a server. + + +
+ + This attribute defines which method can be used to access the target resource. + In an HTTP environment, this would be "GET" or "POST" (other HTTP methods + such as "PUT" and "DELETE" have semantics that are clearly implied by + accessed resources, and do not need to be defined here). + This defaults to "GET". + +
+ +
+ + If present, this property indicates a query media type format that the server + supports for querying or posting to the collection of instances at the target + resource. The query can be + suffixed to the target URI to query the collection with + property-based constraints on the resources that SHOULD be returned from + the server or used to post data to the resource (depending on the method). + +
+ For example, with the following schema: + + + + This indicates that the client can query the server for instances that have a specific name. +
+ +
+ For example: + + + +
+ + If no enctype or method is specified, only the single URI specified by + the href property is defined. If the method is POST, "application/json" is + the default media type. + +
+ +
+ + This attribute contains a schema which defines the acceptable structure of the submitted + request (for a GET request, this schema would define the properties for the query string + and for a POST request, this would define the body). + +
+
+
+
+ +
+ + This property indicates the fragment resolution protocol to use for + resolving fragment identifiers in URIs within the instance + representations. This applies to the instance object URIs and all + children of the instance object's URIs. The default fragment resolution + protocol is "json-pointer", which is defined below. Other fragment + resolution protocols MAY be used, but are not defined in this document. + + + + The fragment identifier is based on RFC 3986, Sec 5, and defines the + mechanism for resolving references to entities within a document. + + +
+ The "json-pointer" fragment resolution protocol uses a JSON Pointer to resolve fragment identifiers in URIs within instance representations. +
+
+ + + +
+ This attribute indicates that the instance value SHOULD NOT be changed. Attempts by a user agent to modify the value of this property are expected to be rejected by a server. +
+ +
+ If the instance property value is a string, this attribute defines that the string SHOULD be interpreted as binary data and decoded using the encoding named by this schema property. RFC 2045, Sec 6.1 lists the possible values for this property. +
+ +
+ + This attribute is a URI that defines what the instance's URI MUST start with in order to validate. + The value of the "pathStart" attribute MUST be resolved as per RFC 3986, Sec 5, + and is relative to the instance's URI. + + + + When multiple schemas have been referenced for an instance, the user agent + can determine if this schema is applicable for a particular instance by + determining if the URI of the instance begins with the the value of the "pathStart" + attribute. If the URI of the instance does not start with this URI, + or if another schema specifies a starting URI that is longer and also matches the + instance, this schema SHOULD NOT be applied to the instance. Any schema + that does not have a pathStart attribute SHOULD be considered applicable + to all the instances for which it is referenced. + +
+ +
+ This attribute defines the media type of the instance representations that this schema is defining. +
+
+ +
+ + This specification is a sub-type of the JSON format, and + consequently the security considerations are generally the same as RFC 4627. + However, an additional issue is that when link relation of "self" + is used to denote a full representation of an object, the user agent + SHOULD NOT consider the representation to be the authoritative representation + of the resource denoted by the target URI if the target URI is not + equivalent to or a sub-path of the the URI used to request the resource + representation which contains the target URI with the "self" link. + +
+ For example, if a hyper schema was defined: + + + +
+ +
+ And a resource was requested from somesite.com: + + + +
+ +
+ With a response of: + + + +
+ +
+ +
+ The proposed MIME media type for JSON Schema is "application/schema+json". + Type name: application + Subtype name: schema+json + Required parameters: profile + + The value of the profile parameter SHOULD be a URI (relative or absolute) that + refers to the schema used to define the structure of this structure (the + meta-schema). Normally the value would be http://json-schema.org/draft-04/hyper-schema, + but it is allowable to use other schemas that extend the hyper schema's meta- + schema. + + Optional parameters: pretty + The value of the pretty parameter MAY be true or false to indicate if additional whitespace has been included to make the JSON representation easier to read. + +
+ + This registry is maintained by IANA per RFC 4287 and this specification adds + four values: "full", "create", "instances", "root". New + assignments are subject to IESG Approval, as outlined in RFC 5226. + Requests should be made by email to IANA, which will then forward the + request to the IESG, requesting approval. + +

Importantly, this +version never constructs the full array. Its memory usage is O(depth) rather +than O(n) (where `n` is the number of flattened elements). + +There's another difference between `flattenObject` and `flattenIter` that's +related to the special case where `depth === 0`. In this case, `flattenObject` +omits the array wrapping `obj` (which is regrettable). + + +### pluck(obj, key) + +Fetch nested property "key" from object "obj", traversing objects as needed. +For example, `pluck(obj, "foo.bar.baz")` is roughly equivalent to +`obj.foo.bar.baz`, except that: + +1. If traversal fails, the resulting value is undefined, and no error is + thrown. For example, `pluck({}, "foo.bar")` is just undefined. +2. If "obj" has property "key" directly (without traversing), the + corresponding property is returned. For example, + `pluck({ 'foo.bar': 1 }, 'foo.bar')` is 1, not undefined. This is also + true recursively, so `pluck({ 'a': { 'foo.bar': 1 } }, 'a.foo.bar')` is + also 1, not undefined. + + +### randElt(array) + +Returns an element from "array" selected uniformly at random. If "array" is +empty, throws an Error. + + +### startsWith(str, prefix) + +Returns true if the given string starts with the given prefix and false +otherwise. + + +### endsWith(str, suffix) + +Returns true if the given string ends with the given suffix and false +otherwise. + + +### parseInteger(str, options) + +Parses the contents of `str` (a string) as an integer. On success, the integer +value is returned (as a number). On failure, an error is **returned** describing +why parsing failed. + +By default, leading and trailing whitespace characters are not allowed, nor are +trailing characters that are not part of the numeric representation. This +behaviour can be toggled by using the options below. The empty string (`''`) is +not considered valid input. If the return value cannot be precisely represented +as a number (i.e., is smaller than `Number.MIN_SAFE_INTEGER` or larger than +`Number.MAX_SAFE_INTEGER`), an error is returned. Additionally, the string +`'-0'` will be parsed as the integer `0`, instead of as the IEEE floating point +value `-0`. + +This function accepts both upper and lowercase characters for digits, similar to +`parseInt()`, `Number()`, and [strtol(3C)](https://illumos.org/man/3C/strtol). + +The following may be specified in `options`: + +Option | Type | Default | Meaning +------------------ | ------- | ------- | --------------------------- +base | number | 10 | numeric base (radix) to use, in the range 2 to 36 +allowSign | boolean | true | whether to interpret any leading `+` (positive) and `-` (negative) characters +allowImprecise | boolean | false | whether to accept values that may have lost precision (past `MAX_SAFE_INTEGER` or below `MIN_SAFE_INTEGER`) +allowPrefix | boolean | false | whether to interpret the prefixes `0b` (base 2), `0o` (base 8), `0t` (base 10), or `0x` (base 16) +allowTrailing | boolean | false | whether to ignore trailing characters +trimWhitespace | boolean | false | whether to trim any leading or trailing whitespace/line terminators +leadingZeroIsOctal | boolean | false | whether a leading zero indicates octal + +Note that if `base` is unspecified, and `allowPrefix` or `leadingZeroIsOctal` +are, then the leading characters can change the default base from 10. If `base` +is explicitly specified and `allowPrefix` is true, then the prefix will only be +accepted if it matches the specified base. `base` and `leadingZeroIsOctal` +cannot be used together. + +**Context:** It's tricky to parse integers with JavaScript's built-in facilities +for several reasons: + +- `parseInt()` and `Number()` by default allow the base to be specified in the + input string by a prefix (e.g., `0x` for hex). +- `parseInt()` allows trailing nonnumeric characters. +- `Number(str)` returns 0 when `str` is the empty string (`''`). +- Both functions return incorrect values when the input string represents a + valid integer outside the range of integers that can be represented precisely. + Specifically, `parseInt('9007199254740993')` returns 9007199254740992. +- Both functions always accept `-` and `+` signs before the digit. +- Some older JavaScript engines always interpret a leading 0 as indicating + octal, which can be surprising when parsing input from users who expect a + leading zero to be insignificant. + +While each of these may be desirable in some contexts, there are also times when +none of them are wanted. `parseInteger()` grants greater control over what +input's permissible. + +### iso8601(date) + +Converts a Date object to an ISO8601 date string of the form +"YYYY-MM-DDTHH:MM:SS.sssZ". This format is not customizable. + + +### parseDateTime(str) + +Parses a date expressed as a string, as either a number of milliseconds since +the epoch or any string format that Date accepts, giving preference to the +former where these two sets overlap (e.g., strings containing small numbers). + + +### hrtimeDiff(timeA, timeB) + +Given two hrtime readings (as from Node's `process.hrtime()`), where timeA is +later than timeB, compute the difference and return that as an hrtime. It is +illegal to invoke this for a pair of times where timeB is newer than timeA. + +### hrtimeAdd(timeA, timeB) + +Add two hrtime intervals (as from Node's `process.hrtime()`), returning a new +hrtime interval array. This function does not modify either input argument. + + +### hrtimeAccum(timeA, timeB) + +Add two hrtime intervals (as from Node's `process.hrtime()`), storing the +result in `timeA`. This function overwrites (and returns) the first argument +passed in. + + +### hrtimeNanosec(timeA), hrtimeMicrosec(timeA), hrtimeMillisec(timeA) + +This suite of functions converts a hrtime interval (as from Node's +`process.hrtime()`) into a scalar number of nanoseconds, microseconds or +milliseconds. Results are truncated, as with `Math.floor()`. + + +### validateJsonObject(schema, object) + +Uses JSON validation (via JSV) to validate the given object against the given +schema. On success, returns null. On failure, *returns* (does not throw) a +useful Error object. + + +### extraProperties(object, allowed) + +Check an object for unexpected properties. Accepts the object to check, and an +array of allowed property name strings. If extra properties are detected, an +array of extra property names is returned. If no properties other than those +in the allowed list are present on the object, the returned array will be of +zero length. + +### mergeObjects(provided, overrides, defaults) + +Merge properties from objects "provided", "overrides", and "defaults". The +intended use case is for functions that accept named arguments in an "args" +object, but want to provide some default values and override other values. In +that case, "provided" is what the caller specified, "overrides" are what the +function wants to override, and "defaults" contains default values. + +The function starts with the values in "defaults", overrides them with the +values in "provided", and then overrides those with the values in "overrides". +For convenience, any of these objects may be falsey, in which case they will be +ignored. The input objects are never modified, but properties in the returned +object are not deep-copied. + +For example: + + mergeObjects(undefined, { 'objectMode': true }, { 'highWaterMark': 0 }) + +returns: + + { 'objectMode': true, 'highWaterMark': 0 } + +For another example: + + mergeObjects( + { 'highWaterMark': 16, 'objectMode': 7 }, /* from caller */ + { 'objectMode': true }, /* overrides */ + { 'highWaterMark': 0 }); /* default */ + +returns: + + { 'objectMode': true, 'highWaterMark': 16 } + + +# Contributing + +See separate [contribution guidelines](CONTRIBUTING.md). diff --git a/node_modules/jsprim/lib/jsprim.js b/node_modules/jsprim/lib/jsprim.js new file mode 100644 index 0000000000..f7d0d81c3f --- /dev/null +++ b/node_modules/jsprim/lib/jsprim.js @@ -0,0 +1,735 @@ +/* + * lib/jsprim.js: utilities for primitive JavaScript types + */ + +var mod_assert = require('assert-plus'); +var mod_util = require('util'); + +var mod_extsprintf = require('extsprintf'); +var mod_verror = require('verror'); +var mod_jsonschema = require('json-schema'); + +/* + * Public interface + */ +exports.deepCopy = deepCopy; +exports.deepEqual = deepEqual; +exports.isEmpty = isEmpty; +exports.hasKey = hasKey; +exports.forEachKey = forEachKey; +exports.pluck = pluck; +exports.flattenObject = flattenObject; +exports.flattenIter = flattenIter; +exports.validateJsonObject = validateJsonObjectJS; +exports.validateJsonObjectJS = validateJsonObjectJS; +exports.randElt = randElt; +exports.extraProperties = extraProperties; +exports.mergeObjects = mergeObjects; + +exports.startsWith = startsWith; +exports.endsWith = endsWith; + +exports.parseInteger = parseInteger; + +exports.iso8601 = iso8601; +exports.rfc1123 = rfc1123; +exports.parseDateTime = parseDateTime; + +exports.hrtimediff = hrtimeDiff; +exports.hrtimeDiff = hrtimeDiff; +exports.hrtimeAccum = hrtimeAccum; +exports.hrtimeAdd = hrtimeAdd; +exports.hrtimeNanosec = hrtimeNanosec; +exports.hrtimeMicrosec = hrtimeMicrosec; +exports.hrtimeMillisec = hrtimeMillisec; + + +/* + * Deep copy an acyclic *basic* Javascript object.
