Not sure where the down vote came from, it's definitely one of the better universal layouts I've seen...

A few points, would add in jest and tests for everything... would wrap the main server entry point so that it only runs when `!module.parent` and can be fully tested.

Thanks brother. Can you tell me more about what you mean by:

"would wrap the main server entry point so that it only runs when `!module.parent` and can be fully tested."

Here's an example:

    // server/index.js
    async function main(skip) {
      if (skip) return;

      ... rest of main ...
    export default main;

module.parent exists when you require in a module, in this case index, say for testing... but not when you execute the module directly `node server/index` for example.

by wrapping your main logic in a function with a skip parameter, if you load the `./index.js` inside `index.test.js` it won't start your server process... in this way you can override whatever modules are used, and test that logic.

So it's another way to accomplish what you might do with supertest right:

export default function startServer() {
  const app = express()

  // ... regular app.use stuff etc

  const server = http.createServer(app)

  if (process.env.NODE_ENV !== 'test') {
    server.listen(process.env.PORT || 80, () => {
      console.log('Listening on %j', server.address())

  return server

import request from 'supertest'
import startServer from '../server'

it('REQUEST: /', async () => {
    const server = startServer()
    const path = '/'
    const res = await request(server).get(path)

No, it's a way to do unit tests without actually starting a server.  but could work for your supertest example for more integration like testing.
