Express-session Req.user Is Undefined

I'm trying to use express session to login users. I'd like users to be able to go to a profile page and view their user data if they have logged in. I've been stuck here for days.

Solution 1:

You should define isLoginedIn funtion in routes.js as follow:

 // route middleware to ensure user is logged in
function isLoggedIn(req, res, next) {
    if (req.isAuthenticated())
        return next();

    res.redirect('/');
}

Then replace:

   app.route('/profile')
        .get(function(req, res){

            console.log('req.user', req.user)

            if(!req.user){
                res.render('profile', {user: "You're not logged in"})
            }   
            if(req.user){
                res.render('profile', {user: req.user})
            }
        })

by:

 // PROFILE SECTION =========================
    app.get('/profile', isLoggedIn, function(req, res) {
        res.render('profile.ejs', {
            user : req.user
        });
    });
