Install with npm:

npm install graphql-yoga --save

Install with yarn:

yarn add graphql-yoga


import { GraphQLServer } from 'graphql-yoga'
// ... or using `require()`
// const { GraphQLServer } = require('graphql-yoga')

const typeDefs = `
  type Query {
    hello(name: String): String!

const resolvers = {
  Query: {
    hello: (_, { name }) => `Hello ${name || 'World'}`,

const server = new GraphQLServer({ typeDefs, resolvers })
server.start(() => console.log('Server is running on localhost:4000'))

See here for more examples and use cases.


Once your graphql-yoga server is running, you can use GraphQL Playground out of the box – typically running on localhost:4000. (Read here for more information.)
