return-reply.mjs

import Fastify from 'fastify'

const app = Fastify({ logger: true })

app.get('/', async (request, reply) => {
  setImmediate(() => {
    reply.send({ hello: 'world' })
  })
  // return reply is needed to tell Fastify we will call
  // reply.send() in the future.
  return reply
})

await app.listen({ port: 3000 })

What about point-of-view, will it be:

app.get('/', async (request, reply) => {
  reply.view('tempalte')
  return reply
});

like this?

yes
