I am working on backbone.js application with node.js as backend server. the application is based on twitter API. When requesting to localhost:8080 I got the error "Cannot GET /" in the browser and I do not know what is the matter. My code is as follows:

server.js

var express = require('express'); var app = express(); var Twit = require('twit') var client = null; function connectToTwitter(){ client = new Twit({ consumer_key: 'xxx' , consumer_secret: 'xxx' , access_token: 'xxx' , access_token_secret: 'xxx' }); } //get the app to connect to twitter. connectToTwitter(); var allowCrossDomain = function(req, response, next) { response.header('Access-Control-Allow-Origin', ""); response.header('Access-Control-Allow-Methods', 'OPTIONS, GET,PUT,POST,DELETE'); response.header('Access-Control-Allow-Headers', 'Content-Type'); if ('OPTIONS' == req.method) { response.send(200); } else { next(); } }; app.configure(function() { app.use(allowCrossDomain); //Parses the JSON object given in the body request app.use(express.bodyParser()); }); //Start server var port = 8080; app.listen( port, function() { console.log( 'Express server listening on port %d in %s mode', port, app.settings.env ); });

Directory structure in general:

C:\Users\eva\Desktop\twitter application\server\server.js \client\index.html \js

Can someone tell me why this error occur?

You need to implement what server must response on / requests. For example:

app.get('/', function(req, res, next) { res.send("Hello world"); });

Without it, express doesn't know how to handle /.
