// index.js file var app = require('express')(); var http = require('http').server(app); var io = require('socket.io')(http); app.get('/', function(req, res){ res.sendfile('index.html'); }); io.on('connection', function(socket){ socket.on('chat message', function(msg){ console.log('message: ' + msg); }); }); http.listen(3000, function(){ console.log('listening on *:3000'); });

the error getting is:
