Node.JS socket io connection

Question

How can I put the server IP address when I connect to the server in the frontend?

var socket = io.connect('http://localhost:3000/panel');

So instead localhost put the correspondent server IP address for the production environment.

Thanks.

So, it is not possible to detect automatically the IP or the hostname? — Gorka

In a production environment, you would typically refer to a DNS hostname such as http://www.google.com though you would of course use your own registered DNS name. — jfriend00

Since this Javascript is executing in the client, you can just do the following:

document.location.hostname contains the hostname, and document.location.port the port. It's as easy as that.
