I've used express-generator to create my app skeleton and since my file that creates the server and my routes are separated, I don't know where to setup the socket.io code. The tutorials usually have the server code, the socket.io code and the routes in 1 file.
app.js contains:
var routes = require('./routes/'); var express = require('express'); var path = require('path'); var logger = require('morgan'); var cookieParser = require('cookie-parser'); var bodyParser = require('body-parser'); var expressSession = require('express-session'); var app = express(); // view engine setup app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'ejs'); // uncomment after placing your favicon in /public //app.use(favicon(path.join(__dirname, 'public', 'favicon.ico'))); app.use(logger('dev')); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: false })); app.use(cookieParser()); app.use(expressSession({ secret: 'secretText', saveUninitialized: true, resave: true })) app.use(express.static(path.join(__dirname, 'public'))); app.use('/', routes.home); // catch 404 and forward to error handler app.use(function(req, res, next) { var err = new Error('Not Found'); err.status = 404; next(err); }); // error handler app.use(function(err, req, res, next) { // set locals, only providing error in development res.locals.message = err.message; res.locals.error = req.app.get('env') === 'development' ? err : {}; // render the error page res.status(err.status || 500); res.render('error'); }); module.exports = app; www contains:

var express = require('express'); var router = express.Router(); var db = require('../helpers/db'); router.get('/', function(req, res, next) { res.send("Hello"); }); module.exports = router; index.js
var home = require('./home'); module.exports = { home };
