Cannot run Next.js app on localhost with nx serve

[tavvy]

Current Behavior

In production mode. When running a next.js app with a custom hostname (--hostname=localhost or set the option in project.json) then the process will eventually error after roughly 120s.

This is because the nx executor next:server is waiting for the server response on port 3000 and always 127.0.0.1.
https://github.com/nrwl/nx/blob/master/packages/next/src/executors/server/server.impl.ts#L85 because we are not forwarding the custom hostname. Next.js will not respond on localhost by default: vercel/next.js#51378 and so we will retry 120 times before exiting with an unhandled exception error.

node:internal/process/promises:288
            triggerUncaughtException(err, true /* fromPromise */);
            ^
Error: connect ECONNREFUSED 127.0.0.1:3000
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1494:16) {
  errno: -61,
  code: 'ECONNREFUSED',
  syscall: 'connect',
  address: '127.0.0.1',
  port: 3000
}

This simple change would fix it:

await waitForPortOpen(port, { host: options.hostname });

Expected Behavior

I should be able to start my next application with the next:server executor on a custom hostname
