How to get user session from passport.js? - node.js

Question

My problem is with 2 files in my project: server.js (where i'am going to use the user session) and route.js(define my routes).
I've managed to get the user session in routes.js with req.user() but not in app.js with
here is the code of route.js:
module.exports = function(app, passport) {
// LOGIN
// show the login form
app.get('/', function(req, res) {
// render the page and pass in any flash data if it exists
res.render('login.ejs', { message: req.flash('loginMessage') });
});
// process the login form
app.post('/login', passport.authenticate('local-login', {
successRedirect : '/profile', // redirect to the secure profile section
failureRedirect : '/', // redirect back to the signup page if there is an error
failureFlash : true // allow flash messages
}),
function(req, res) {
if (req.body.remember) {
req.session.cookie.maxAge = 1000 * 60 * 3;
} else {
req.session.cookie.expires = false;
}
res.redirect('/');
});
// PROFILE SECTION =========================
// we will want this protected so you have to be logged in to visit
// we will use route middleware to verify this (the isLoggedIn function)
app.get('/profile', isLoggedIn, function(req, res) {
var a = req.user.Email;
console.log(a);
res.render('profile.ejs', {
user : req.user // get the user out of session and pass to template
});
});
// =====================================
// LOGOUT ==============================
// =====================================
app.get('/logout', function(req, res) {
req.logout();
res.redirect('/');
});
};
// route middleware to make sure
function isLoggedIn(req, res, next) {
// if user is authenticated in the session, carry on
if (req.isAuthenticated())
return next();
// if they aren't redirect them to the home page
res.redirect('/');
}
and server.js :
var express = require('express');
var app = express();
var port = process.env.PORT || 8080;
var passport = require('passport');
var flash = require('connect-flash');
var server = require('http').createServer(app);
// configuration ===============================================================
require('./config/passport')(passport); // pass passport for configuration
app.configure(function() {
// set up our express application
app.use(express.logger('dev')); // log every request to the console
app.use(express.cookieParser()); // read cookies (needed for auth)
app.use(express.bodyParser()); // get information from html forms
// Make the files in the public folder available to the world
app.use(express.static(__dirname + '/public'));
// Tell express where it can find the templates
app.set('views', __dirname + '/views');
app.set('view engine', 'ejs'); // set up ejs for templating
// required for passport
app.use(express.session({ secret: 'chiftestisalwaysrunning' } )); // session secret
app.use(passport.initialize());
app.use(passport.session()); // persistent login sessions
app.use(flash()); // use connect-flash for flash messages stored in session
});
// routes ======================================================================
require('./app/routes.js')(app, passport); // load our routes and pass in our app and fully configured passport
/*i want to get the user session*/
// launch ======================================================================
server.listen(port);
console.log('The magic happens on port ' + port);
