Quick start

Start

Make a schema, create Yoga and start a Node server:

import { createSchema, createYoga } from 'graphql-yoga'
import { createServer } from 'node:http'

const yoga = createYoga({
  schema: createSchema({
    typeDefs: /* GraphQL */ `
      type Query {
        hello: String
      }
    `,
    resolvers: {
      Query: {
        hello: () => 'Hello from Yoga!'
      }
    }
  })
})

const server = createServer(yoga)

server.listen(4000, () => {
  console.info('Server is running on http://localhost:4000/graphql')
})

Overview

• Easiest way to run a GraphQL server: Sensible defaults & includes everything you need with minimal setup (we also export a platform/env-agnostic handler so you can build your own wrappers easily).
• Includes Subscriptions: Built-in support for GraphQL subscriptions using Server-Sent Events.
• Compatible: Works with all GraphQL clients (Apollo, Relay, Urql...) and fits seamless in your GraphQL workflow.
• WHATWG Fetch API: the core package depends on WHATWG Fetch API so it can run and deploy on any environment (Serverless, Workers, Deno, Node).
• Easily Extendable: New GraphQL-Yoga support all envelop plugins.
