Example of embedding Apollo GraphQL server inside next.js

index.ts

import * as express from 'express'
import * as next from 'next'
import { ApolloServer, gql } from 'apollo-server-express'

const port = parseInt(process.env.PORT, 10) || 3000
const dev = process.env.NODE_ENV !== 'production';

const app = next({ dev, quiet: false })
const handle = app.getRequestHandler()

const typeDefs = gql`
 type Query {
   status: String
 }
`

const resolvers = {
 Query: {
   status: () => 'ok'
 }
}

const apollo = new ApolloServer({typeDefs, resolvers})

app.prepare().then(() => {
  const server = express()
  apollo.applyMiddleware({ app: server })

  server.get('*', (req, res) => {
    return handle(req, res)
  })

  server.listen(port, (err) => {
    if (err) throw err
    console.log(`> Ready on http://localhost:${port}`)
  })
})
