Maintaining end & README.md update

[kornfleks]

Hello,

As graphql-let is not actively maintains anymore, I think a disclaimer should be add at the start of the README file.

Two years ago I add the opportunity to use this tool and it has been the greatest dev experience I had with GraphQL & React. I really want to thanks @piglovesyou and others maintainers for producing this tool.

As today, I again have to use GraphQL with React (nextjs) in a monorepo, I am facing the same tooling hell where you don't know what to choose and how to configures it.

I have ended up using GraphqlCodegen and succeed to mimic the experience of graphql-let.

Here is how I did it:

For each .graphql files generate a .graphql.ts.
codegen.ts:

const config: IGraphQLConfig = {
  // using projects to support multiple GraphQL schema
  projects: {
    admin: {
      schema:  'http://localhost:8080/v1/graphql',
      extensions: {
        codegen: {
          generates: {
            './src/admin.ts': {
              config: generateConfig,
              plugins: ['typescript'],
            },
            admin: {
              preset: 'near-operation-file',
              presetConfig: {
                extension: '.graphql.ts',
                baseTypesPath: '~@foo-bar/graphql-codegen/src/admin',
              },
              documents: [
                '../../apps/**/src/pages/api/**/*.graphql',
              ],
              plugins: ['typescript-operations', 'typed-document-node'],
              config: generateConfig,
            },
          },
        }
      },
    },
    // ...
  }
}

To be able to do import like import { MyDocument } from './foo.graphql' we have to resolves the alias in the webpack config.
webpack.config.js:

{
  resolve: {
    extensionAlias: {
      '.graphql': ['.graphql.ts'],
    },
  }
}

You can also hide the .graphql.ts files from your editor so you don't even thinks about the code generation.

Best regards.
