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

Integration with Hapi
Hapi allows you to build powerful, scalable applications, with minimal overhead and full out-of-the-box functionality - your code, your way.
It continues to be the proven choice for enterprise-grade backend needs.
Installation
npm i @hapi/hapi graphql-yoga graphql
Example
import http from 'node:http'
import { Readable } from 'node:stream'
import { createSchema, createYoga } from 'graphql-yoga'
import Hapi from '@hapi/hapi'
import { schema } from './my-graphql-schema'
interface ServerContext {
req: Hapi.Request
h: Hapi.ResponseToolkit
}
const yoga = createYoga<ServerContext>({ schema })
const server = Hapi.server({ port: 4000 })
server.route({
method: '*',
path: yoga.graphqlEndpoint,
options: {
payload: {
// let yoga handle the parsing
output: 'stream'
}
},
handler: async (req, h) => {
const { status, headers, body } = await yoga.handleNodeRequest(req.raw.req, { req, h })
const res = h.response(
Readable.from(body, {
// hapi needs the stream not to be in object mode
objectMode: false
})
)
for (const [key, val] of headers) {
res.header(key, val)
}
return res.code(status)
}
})
server.start()
The GraphQL Yoga server should now be available at http://localhost:4000/graphql.
