v2
Quick Start
⚠️
This is the documentation for the old GraphQL Yoga version 2. We recommend upgrading to the latest GraphQL Yoga version 5.

Migrate to GraphQL Yoga v5

Quick Start

GraphQL Yoga is a batteries-included cross-platform GraphQL over HTTP spec-compliant GraphQL Server using Envelop, and GraphQL Tools that runs anywhere.

Installation

Terminal
yarn add @graphql-yoga/node graphql

Usage

You will need to provide a schema to Yoga, either by an existing executable schema or by providing your type definitions and resolver map.

import { createServer } from '@graphql-yoga/node'
 
const server = createServer({
  schema: {
    typeDefs: /* GraphQL */ `
      type Query {
        hello: String
      }
    `,
    resolvers: {
      Query: {
        hello: () => 'Hello from Yoga!'
      }
    }
  }
})
 
server.start()
💡

Yoga uses GraphQL Tools under the hood so you’ll want to follow the makeExecutableSchema pattern.

That is it!

Now visit http://localhost:4000/graphql to execute the following query operation:

query HelloWorld {
  hello
}

Using Existing Schema

You can also pass an existing GraphQLSchema instance to createServer.

If you’re using a library such as Pothos, GraphQL Nexus, gqtx, or vanilla graphql-js, you simply can pass the GraphQLSchema to schema:

import { createServer } from '@graphql-yoga/node'
import { schema } from './schema'
 
const server = createServer({ schema })
 
server.start()
