Question

I have seen some post on this forum regarding Socket.IO and node.js. But still isn’t working optimally.

port 80 and port 8080 are used by my webserver for different applications. So in App.js and my socket connection I added port 8081 instead of 8080.

I’m getting the websocket connection invalid message. After 10 seconds or so it has created the websocket and i’m able to use it perfectly well.

But 10 seconds is a too long. Any ideas how to fix this?

script.js:

 <script>
var socket = io.connect('http://domainname.nl:8081');


socket.on('connect', function(){

socket.emit('adduser', "<?php echo $user->first_name; ?>");
});

app.js

var app = require('express').createServer()
var io = require('socket.io').listen(8081);

app.listen(8081);

// routing
app.get('/', function (req, res) {
  res.sendfile(__dirname + '/index.html');
});

UPDATE:

When I have changed it. I still got the problem. The sockets works but takes 10 seconds to get connected

You’re effectively trying to start two different servers, one for your app and one for socket.io, both using the same port, 8081:

var app = require('express').createServer()
var io = require('socket.io').listen(8081);

app.listen(8081);

You can pass a port number to socket.io like this, but if you’re going to run it with a node http server you should pass that (i.e., app) to listen, like so:

var app = require('express').createServer()
var io = require('socket.io').listen(app);

app.listen(8081);
