Heroku + node.js error (Web process failed to bind to $PORT within 60 seconds of launch)

Question

I have my first node.js app (runs fine locally) - but I am unable to deploy it via heroku (first time w/ heroku as well). The code is below. SO doesn\'t let me write so much

Answer 1

Heroku dynamically assigns your app a port, so you can't set the port to a fixed number. Heroku adds the port to the env, so you can pull it from there. Switch your listen to this:

.listen(process.env.PORT || 5000)

That way it'll still listen to port 5000 when you test locally, but it will also work on Heroku.

You can check out the Heroku docs on Node.js here.
