Docs

Installation

npm i @graphql-yoga/node graphql

Quickstart

You will need to provide 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()

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.
