Linting a single file is super slow

[kevinbarabash]

It takes about 45 seconds to lint a single file.

Here's a paired down version of my config:

module.exports = {
    parserOptions: {
        schema: pathToSchemaFile,
        schemaOptions: {
            assumeValid: true,
        },
        operations: "javascript/**/*.{ts,tsx}",
    },
    overrides: [
        {
            files: ["*.ts", "*.tsx"],
            processor: "@graphql-eslint/graphql",
        },
        {
            files: ["*.graphql"],
            parser: "@graphql-eslint/eslint-plugin",
            plugins: ["@graphql-eslint"],
            rules: {
                "@graphql-eslint/known-type-names": "error",
                // "@graphql-eslint/unique-operation-name": "error",
                "@graphql-eslint/require-id-when-available": [
                    "error",
                    {fieldName: ["id", "cacheId"]},
                ],
                "prettier/prettier": "off",
            },
        },
    ],
}

I'm running eslint using the following command:

eslint --debug --ext .js --ext .jsx --ext .ts --ext .tsx --ext .graphql --quiet javascript/cp-shared-package/revision-history-modal.tsx

I'm seeing the following output:

followed by thousands of lines of similar output. It looks like it's parsing every single .ts(x) file in my project. Is there a way to keep it from doing this?

it can be slow because graphql-eslint loads all operations provided by parserOptions.operations
