Integration with Hapi

💡

This page is currently under construction and expected to change. Please feel free to reach out to us directly in case you are having any troubles.

Hapi allows you to build powerful, scalable applications, with minimal overhead and full out-of-the-box functionality.

GraphQL Mesh can be integrated easily as a route to the existing Hapi application with a few lines of code.

Example

import http from 'node:http'
import { Readable } from 'node:stream'
import { createServeRuntime } from '@graphql-mesh/serve-runtime'
import Hapi from '@hapi/hapi'
import { schema } from './my-graphql-schema'
 
interface ServerContext {
  req: Hapi.Request
  h: Hapi.ResponseToolkit
}
 
const mesh = createServeRuntime<ServerContext>(/* Your configuration */)
 
const server = Hapi.server({ port: 4000 })
 
server.route({
  method: '*',
  path: mesh.graphqlEndpoint,
  options: {
    payload: {
      // let mesh handle the parsing
      output: 'stream'
    }
  },
  handler: async (req, h) => {
    const { status, headers, body } = await mesh.handleNodeRequestAndResponse(
      req.raw.req,
      req.raw.res,
      {
        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 Mesh server should now be available at http://localhost:4000/graphql.
