Additional functionality: Adding and/or updating user info in database.

Here is the /register post route code which will take the user's information and insert it into Mongo. The User.create method is used to create a new user in the database.

// POST /register
router.post('/register', function(req, res, next) {
    if (req.body.email &&
        req.body.name &&
        req.body.favoriteBook &&
        req.body.password &&
        req.body.confirmPassword) {

        // confirm that user typed the same password twice
        if (req.body.password !== req.body.confirmPassword) {
            var err = new Error('Passwords do not match.');
            err.status = 400;
            return next(err);
        }

        //create object with form input
        var userData = {
            email: req.body.email,
            name: req.body.name,
            favoriteBook: req.body.favoriteBook,
            password: req.body.password
        };

        // use schema's 'create' method to insert document into Mongo
        User.create(userData, function (error, user) {
            if (error) {
                return next(error);
            } else {
                req.session.userId = user._id;
                return res.redirect('/profile');
            }
        })  

    } else {
        var err = new Error('All fields required.');
        err.status = 400;
        return next(err);
    }
});

After the user is registered and logged in, I want to update his information in the database. As an example, let's say I want to record the number of times the user has visited the 'Contact' page of the website. So the first time he visits the Contact page, a new field will be created in the database for the user with the value of 1. Every time he visits the 'Contact page afterwards, the value will be updated. (Would I need to make any modifications to the UserSchema?) Any help would be greatly appreciated.

Code for /contact route:

// GET /contact
router.get('/contact', function(req, res, next) {
  return res.render('contact', { title: 'Contact' });
});
