var express = require('express');
var app = express.createServer();
var socket = require('socket.io');
app.configure(function(){
  app.use(express.static(__dirname + '/'));
});
var server = app.listen(8081);
var io = socket.listen(server);
io.sockets.on('connection', function (socket) {
 console.log("connnect");
 socket.on('disconnect', function (socket) {
  console.log("disconnect");
 });
});

Client Code ( index.html )
