⚠️
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
Migrate to GraphQL Yoga v5
Migration from Express GraphQL
Installation
You can start by installing graphql-yoga package.
Terminal
yarn add @graphql-yoga/nodeReplace Express GraphQL’s Middleware
You should replace Express GraphQL’s middleware with GraphQL Yoga’s;
const express = require('express')
- const { graphqlHTTP } = require('express-graphql')
+ const { createServer } = require('@graphql-yoga/node')
const { schema } = require('./schema')
const app = express()
- app.use('/graphql', graphqlHTTP(req => ({
- schema: schema,
- context: {
- token: req.headers.authorization
- },
- graphiql: true
- })))
+ const yoga = createServer({
+ schema,
+ context: (req) => ({ // Context factory gets called for every request
+ myToken: req.headers.get('authorization')
+ }),
+ graphiql: true
+ })
+
+ app.use('/graphql', yoga)
app.listen(4000)
console.log('Running a GraphQL API server at http://localhost:4000/graphql')💡
schema, context and other parameters can be passed dynamically per HTTP
request. context parameter of GraphQL Yoga can be a factory function but
schema cannot. So you should use
@envelop/use-lazy-loaded-schema
for the same behavior.
