Unable to receive events in SOCKET.IO client - node.js

Question

I am new to socket.io and i am trying out the examples mentioned on their site. I am going good with it but problem occurs when i try to use io.emit on the server side and try to receive on client side.
Here is my server code
var io=require("socket.io").listen(8888);
io.set('log level',1);
io.on('connection',function(socket){
socket.emit('hi');
console.log("Connected");
});
And my client's code
<script src="http://localhost:8888/socket.io/socket.io.js"></script>
<script>
var socket=io.connect("http://localhost:8888");
socket.set('log_level',1);
socket.on('hi',function(){
console.log('received');
});
</script>
The problem is i don't see the message 'received' in the console! The answer may be trivial but i tried experimenting but failed everytime. Please guide....
I am on ubuntu firefox. node version: 0.8.7

Answer 1

So you should have this on the serve side:
var io = require('socket.io').listen(88888);
io.set('log level',1);
io.sockets.on('connection', function (socket) {
socket.emit('hi);
console.log("Connected");
});
});
And you should have this on the client side:
<script src="http://localhost:8888/socket.io/socket.io.js"></script>
<script>
var socket = io.connect('http://localhost:8888/');
socket.set('log_level',1);
socket.on('hi', function () {
console.log(data);
socket.emit('my other event', { my: 'data' });
});
</script>
WebSockets like many html5 features does not work in a non webserver environment. I mean It won't work if you are accessing your client with the file protocol.
You need to have a http server.
What I do to get things done easily, I use python built-in web-server. It does the job.
Just spawn it in you client folder like this:
python -m SimpleHTTPServer
And then point your browser to port 8000 (default).
I've made a boiler plate socket.io app that you can clone and even push directly to dotCloud.com
This is a simple example and could help you to get started with socket.io.

Answer 2

Look for examples on the soket.io GitHub page.
You wrote: io.on('connection' instead io.sockets.on('connection'
This code should work fine:
var io = require('socket.io').listen(8888);
io.set('log level', 1);
io.sockets.on('connection', function(socket){
socket.emit('hi');
console.log("Connected");
});
