So I did npm install express and npm install socket.io and I brought the node_modules folders to my server folder where I am using WAMP.
Using this as server.js:
var app = require('express').createServer();
var io = require('socket.io').listen(app);
io.sockets.on('connection', function (socket) {
console.log('Someone connected!');
socket.on('set nickname' , function (nickname) {
socket.nickname = nickname;
console.log(nickname + ' just connected!');
});
});
app.listen(8080);
and using this as client.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" ".dtd">

<head>
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1" />
<title>Untitled 4</title>
<script src=".io.js"></script>
<script>
var socket = io.connect('http://localhost:8080');
socket.on('connect', function () {
console.log('We are connected!');
var name = prompt('What is your name?');
this.emit('set namename', name, function (success) {
console.log('The server got the message!');
if (!success) {
console.log('Nickname is in use!');
}
});
});
</script>
</head>
<body>
</body>
</html>
the error I get is Uncaught TypeError: Object #<Object> has no method 'connect'
I know I used a different than socket.io.js becase I don't know where to get the /socket.io/socket.io.js. I tried doing node_modules/socket.io/lib/socket.io.js which is another one I found i my node_modules folder, but that isn't it.
I also started my server and I got socket.io started so I know that works.

Reset to default 4The error you got is because the source of socket.io script (into index.html) is wrong. So change this:
<script src="http://cdn.socket.io/stable/socket.io.js"></script>
in this:
<script src="http://localhost:3000/socket.io/socket.io.js"> </script>
And yes, socket.io is a folder into the root server directory and my server-side socket is listening on port 3000.
