I use the node.js and socket.io.

My application runs on the port 3000. The application starts from from the url: mydomain.com:3000/

I want to run the application from mydomain.com – I want to remove the port from the url.

Where and how can I set this setting?

    Find your server.listen call and change the port from 3000 to 80. Don’t forget that you have to run the program with the CAP_NET_BIND_SERVICE capability (see capabilities(7) for details) in order to bind to ports less than 1024 on Linux systems. root privilege will contain this, and other, privileges.
