Sockets Connecting

Question

I have been trying to get my WAMP Webserver run with socket.io but I just cannot seem to get it to work.

My socket server is on port 3000 and the WAMP on port 80. I know that both servers work.

Web Server Client Code:

<script src="/socket.io/socket.io.js"></script>
<script>
    var socket = io('http://[ip address]:3000');
    socket.on('buzz', function (data) {
    console.log(data);
});
</script>

Console Error:

Uncaught ReferenceError: io is not defined
at (index):97

UPDATE I was missing the socket.io.js file. But now I am getting

GET http://[[IP]]:3000/socket.io/?EIO=3&transport=polling&t=LxfQwpE
net::ERR_CONNECTION_TIMED_OUT

In the console every few seconds.

Does your web developer console in your web browser tell you anything? Suggests socket.io.js has not been included when you try and instantiate the `io` object. — ficuscr, Oct 04 '17 at 21:49
Cool. Easy fix. Can also use CDN with ease for client includes. ``... just plugin correct version numbers. — ficuscr, Oct 04 '17 at 22:05
@ficuscr Thanks! That worked but I am now getting the above (edited OP) error msg. — Samyok Nepal, Oct 04 '17 at 22:07
What happens when you ping your server? I know you said "both servers work", but your socket server might not be receiving the request. — TinkerTenorSoftwareGuy, Oct 04 '17 at 22:23
When I go to localhost:3000, the server responds with index.html (node server) — Samyok Nepal, Oct 04 '17 at 22:30

As I recall, this problem was solved by installing a NGINX reverse proxy -- I believe I followed the instructions here: Socket.io with nginx

This was one of my first projects, but I thought I would point people in the right direction in case other students wish to use a WAMP backend and Socket.io.
