Features
REST API
⚠️
This is the documentation for the old GraphQL Yoga version 4. We recommend upgrading to the latest GraphQL Yoga version 5.

Migrate to GraphQL Yoga v5

Sofa API

Sofa takes your GraphQL Schema, looks for available queries, mutations and subscriptions and turns all of that into REST API.

Installation

npm i @graphql-yoga/plugin-sofa

Example

server.ts
import { createServer } from 'http'
import { createSchema, createYoga } from 'graphql-yoga'
import { useSofa } from '@graphql-yoga/plugin-sofa'
