Socket.io on Heroku: client-side code

Question

I've been having trouble loading the socket.io library for my JS client code on a Node.js app hosted on Heroku.

For now, I have this line at the end of my index.html file:

<script type="text/javascript" src="/socket.io/socket.io.js"></script> 

But then, when I do socket = io.connect('http://myherokuapp');in my JS client code, I get an expected 'io is not defined' error.

Any idea how to correctly load the library on Heroku?

Thanks!

Answer 1

Ok so I finally found my way through. I'm sharing in case it helps someone.

I load the script in index.html this way:

<script type="text/javascript" src="http://myapp.herokuapp.com/socket.io/socket.io.js"></script>

It makes sense because the client-side library is actually loaded from the node server and shouldn't be pushed manually.

In my client-side JS file, I instantiate the socket this way:

socket = io.connect('http://myapp.herokuapp.com/');

Also, and this goes beyond the scope of this question, but you can't use websocket on Heroku for now. They have a little note about that here.

Hope this helps!
