GraphQL Tag Pluck

graphql-tag-pluck will take JavaScript code as an input and will pluck all template literals provided to graphql-tag.

Input:

import gql from 'graphql-tag'

const fragment = gql`
  fragment Foo on FooType {
    id
  }
`

const doc = gql`
  query foo {
    foo {
      ...Foo
    }
  }

  ${fragment}
`

Output:

fragment Foo on FooType {
  id
}

query foo {
  foo {
    ...Foo
  }
}

Originally created because of https://graphql-code-generator.com/.

Usage

graphql-tag-pluck is installable via NPM (or Yarn):

$ npm install graphql-tag-pluck

Once installed you can pluck GraphQL template literals using one of the following methods:

import gqlPluck, {
  gqlPluckFromFile,
  gqlPluckFromCodeString,
} from 'graphql-tag-pluck'

// Returns promise
gqlPluck.fromFile(filePath, {
  useSync: true, // Optional, will return string if so
})

// Returns string
gqlPluck.fromFile.sync(filePath)

// Returns string
gqlPluck.fromCodeString(codeString, {
  fileExt: '.ts', // Optional, defaults to '.js'
})

Template literals leaded by magic comments will also be extracted :-)

/* GraphQL */ `
  enum MessageTypes {
    text
    media
    draftjs
  }
`

supported file extensions are: .js, .jsx, .ts, .tsx, .flow, .flow.js, .flow.jsx, .graphqls, .graphql, .gqls, .gql.

Options

I recommend you to look at the source code for a clearer understanding of the transformation options.

• gqlMagicComment

  The magic comment anchor to look for when parsing GraphQL strings. Defaults to graphql, which may be translated into /* GraphQL */ in code.

• globalGqlIdentifierName

  Allows to use a global identifier instead of a module import.

  // `graphql` is a global function
  export const usersQuery = graphql`
    {
      users {
        id
        name
      }
    }
  `

• modules

  An array of packages that are responsible for exporting the GraphQL string parser function. The following modules are supported by default:

  {
      modules: [
          {
            // import gql from 'graphql-tag'
            name: 'graphql-tag',
          },
          {
            name: 'graphql-tag.macro',
          },
          {
            // import { graphql } from 'gatsby'
            name: 'gatsby',
            identifier: 'graphql',
          },
          {
            name: 'apollo-server-express',
            identifier: 'gql'
          },
          {
            name: 'apollo-server',
            identifier: 'gql'
          },
          {
            name: 'react-relay',
            identifier: 'graphql'
          },
          {
            name: 'apollo-boost',
            identifier: 'gql'
          },
          {
            name: 'apollo-server-koa',
            identifier: 'gql',
          },
          {
            name: 'apollo-server-hapi',
            identifier: 'gql',
          },
          {
            name: 'apollo-server-fastify',
            identifier: 'gql',
          },
          {
            name: ' apollo-server-lambda',
            identifier: 'gql',
          },
          {
            name: 'apollo-server-micro',
            identifier: 'gql',
          },
          {
            name: 'apollo-server-azure-functions',
            identifier: 'gql',
          },
          {
            name: 'apollo-server-cloud-functions',
            identifier: 'gql',
          },
          {
            name: 'apollo-server-cloudflare',
            identifier: 'gql',
          }
      ]
  }
