Node.js, Express, Socket.io App Connection Error

I've got a simple app which uses socket.io module for node.js. When i run my server with node express_server.js command it works ok, but when i want to open my http://localhost:808

Solution 1:

There is no router defined. Try add this after creating the app (var app = express()):

app.get('/', function(req, res) {
    // res.send('hello world');
    res.sendfile('index.html');
});

Solution 2:

Express is a framework that amongst other stuff replaces the 'http' module. You appear to be trying to use both together. Try this:

var express = require('express'),
var app = express();

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

var port = Number(process.env.PORT || 8080);
app.listen(port, function() {
  console.log("Listening on " + port);
});

Credit to Ben for the nudge on the get method.
