Import & export definitions in GraphQL SDL

graphql-import

Import & export definitions in GraphQL SDL (also refered to as GraphQL modules)

Install

yarn add graphql-import

Usage

import { importSchema } from 'graphql-import'
import { makeExecutableSchema } from 'graphql-tools'

const typeDefs = importSchema('schema.graphql')
const resolvers = {}

const schema = makeExecutableSchema({ typeDefs, resolvers })

Example

Assume the following directory structure:

.
├── a.graphql
├── b.graphql
└── c.graphql

a.graphql

# import B from "b.graphql"

type A {
  # test 1
  first: String
  second: Float
  b: B
}

b.graphql

# import C from 'c.graphql'

type B {
  c: C
  hello: String!
}

c.graphql

type C {
  id: ID!
}

Running console.log(importSchema('a.graphql')) procudes the following output:

type A {
  first: String
  second: Float
  b: B
}

type B {
  c: C
  hello: String!
}

type C {
  id: ID!
}

Please refer to src/index.test.ts for more examples.

Development

The implementation documentation documents how things are implemented under the hood. You can also use the VSCode test setup to debug your code/tests.
