Heroku handles the proxy between your app to port 80 (or SSL port when applicable) for you. But the port for your app is not fixed, it is potentially variable but always available as an Environment Variable PORT.

So in your node.js app, you should listen to process.env.PORT instead of a fixed value. Further, to make the app run both locally and on Heroku environment, you can do process.env.PORT || 3000 assuming 3000 is your choice of the port number for local development purposes.

See https://devcenter.heroku.com/articles/dynos#local-environment-variables for further details.

Thanks for the answer, to handle static files Heroku will handle it alone?
@airsoftFreak can you elaborate on what you mean by handle static files? If you mean creating a server just to serve static HTML/CSS/JavaScript then you still have to go through the same process but just use the technique described here expressjs.com/en/starter/static-files.html if you use express.js
I read online that node.js isn't that good handling static files like images, and so on. While nginx is good for handling this kind of stuff.
@airsoftFreak with heroku the most "front-line" proxy is not in your hand to control. If you insist on utilizing Nginx or Apache and configure them yourself, then you better start with a VPS like digital ocean.
@airsoftFreak you don't need to configure the value of process.env.PORT, simply use it like what the answer has. And load balancing is handled for you, provided that you use more than one workers (dynos)
