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

Integration with SvelteKit

SvelteKit (opens in a new tab) is the fastest way to build svelte apps. It is very simple and lets you build the frontend & backend in a single place.

You can add GraphQL Yoga with a few lines of code and get the benefits of GraphQL & SvelteKit at the same time. Envelop ecosystem (opens in a new tab) for example!


In a SvelteKit project:

yarn add @graphql-yoga/common graphql


Create your GraphQL Endpoint

Create the following file:

import { createServer } from '@graphql-yoga/common'
import type { RequestEvent } from '@sveltejs/kit'
const yogaApp = createServer<RequestEvent>({
  schema: {
    typeDefs: /* GraphQL */ `
      type Query {
        hello: String
    resolvers: {
      Query: {
        hello: () => 'SvelteKit - GraphQL Yoga'
  graphiql: {
    endpoint: '/api/graphql'
export { yogaApp as get, yogaApp as post }
