GraphQL Tag Pluck

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

$ npm install @graphql-tools/graphql-tag-pluck

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

import gqlPluck, { gqlPluckFromFile, gqlPluckFromCodeString } from '@graphql-tools/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',
    },
  ];
}
