⚠️

This is the documentation for the old GraphQL Yoga version 3. We recommend upgrading to the latest GraphQL Yoga version 5.

Migrate to GraphQL Yoga v5

Integration with SvelteKit

SvelteKit is the fastest way to build svelte apps. It is very simple, and let you build 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 for example!

Installation

In a SvelteKit project:

Terminal

yarn add graphql-yoga graphql

Example

Create your graphql endpoint

Create the file src/routes/api/graphql.ts:

src/routes/api/graphql.ts

import { createYoga, createSchema } from 'graphql-yoga'
import type { RequestEvent } from '@sveltejs/kit'
 
const yogaApp = createYoga<RequestEvent>({
  schema: createSchema({
    typeDefs: `
			type Query {
				hello: String
			}
		`,
    resolvers: {
      Query: {
        hello: () => 'SvelteKit - GraphQL Yoga'
      }
    }
  }),
  // Needed to be defined explicitly because our endpoint lives at a different path other than `/graphql`
  graphqlEndpoint: '/api/graphql'
})
 
export { yogaApp as get, yogaApp as post }
