graphql

GraphQL.js provides a reference implementation for the GraphQL specification but is also a useful utility for operating on GraphQL files and building sophisticated tools.

This primary module exports a general purpose function for fulfilling all steps of the GraphQL specification in a single operation, but also includes utilities for every part of the GraphQL specification:

  • Parsing the GraphQL language.
  • Building a GraphQL type schema.
  • Validating a GraphQL request against a type schema.
  • Executing a GraphQL request against a type schema.

This also includes utility functions for operating on GraphQL types and GraphQL documents to facilitate building tools.

You may also import from each sub-directory directly. For example, the following two import statements are equivalent:

import { parse } from 'graphql';
import { parse } from 'graphql/language';
