node.JS Express passport routing - node.js

Question

I've created a simple project, with 3 pages: Home, Contact and About.
Everything was working, then I wanted to add users registration with mongo.
So I followed this tutorial
But, when I add somes new routes, I can't acces any more pages.
This was my index.js when I can acces my 3 pages
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res) {
res.render('index', { title: 'Express' });
});
/* GET contact page. */
router.get('/contact', function(req, res) {
res.render('contact');
});
/* POST contact page (submit). */
router.post('/contact', function(req, res) {
res.render('contact', { name: req.param('name') });
});
/* GET home page. */
router.get('/home', function(req, res) {
res.render('home');
});
/* POST home page (submit). */
router.post('/home', function(req, res) {
res.render('home', { comm: req.param('comm') });
});
/* GET about page. */
router.get('/about', function(req, res) {
res.render('about');
});
module.exports = router;
all simple and working.
and now, it's like that :
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res) {
res.render('index', { title: 'Express' });
});
/* GET contact page. */
router.get('/contact', function(req, res) {
res.render('contact');
});
/* POST contact page (submit). */
router.post('/contact', function(req, res) {
res.render('contact', { name: req.param('name') });
});
/* GET home page. */
router.get('/home', function(req, res) {
res.render('home');
});
/* POST home page (submit). */
router.post('/home', function(req, res) {
res.render('home', { comm: req.param('comm') });
});
/* GET about page. */
router.get('/about', function(req, res) {
res.render('about');
});
module.exports = router;
module.exports = function(passport){
// /* GET login page. */
// router.get('/', function(req, res) {
// // Display the Login page with any flash message, if any
// res.render('index', { message: req.flash('message') });
// });
/* Handle Login POST */
router.post('/login', passport.authenticate('login', {
successRedirect: '/home',
failureRedirect: '/',
failureFlash : true
}));
/* GET Registration Page */
router.get('/signup', function(req, res){
res.render('register',{message: req.flash('message')});
});
/* Handle Registration POST */
router.post('/signup', passport.authenticate('signup', {
successRedirect: '/home',
failureRedirect: '/signup',
failureFlash : true
}));
return router;
}
and now, no routes are showed.
Any ideas ?
thanks !

Answer 1

Your module expects a passport object
module.exports = function(passport){
but you're not calling it with a passport object in app.js
var routes = require('./routes/index');
also, you'll need to defined passport before calling the routes module. So in the end you'll need to modify your app.js to look something like this:
var passport = require('passport');
var expressSession = require('express-session');
app.use(expressSession({secret: 'mySecretKey'}));
app.use(passport.initialize());
app.use(passport.session());
...
var routes = require('./routes/index')(passport);
...
app.use('/', routes);
