Authentication via Passport (Node.js, Express) immediately after user registration

Question

Node.js

Friends,
You need to make a transition to another page immediately after registering a new user.
I took this code from an open project https://github.com/linnovate/mean/blob/master/app/...

exports.create = function(req, res) {
    var user = new User(req.body);
    var message = null;

    user.provider = 'local';
    user.save(function(err) {
        if (err) {
            switch(err.code){
                case 11000:
                case 11001:
                    message = 'Username already exists';
                    break;
                default: 
                    message = 'Please fill all the required fields';
            }

            return res.render('users/signup', {
                message: message,
                user: user
            });
        }
        req.logIn(user, function(err) {
            if (err) return next(err);
            return res.redirect('/');
        });
    });
};

I can’t understand why when I use this piece in my project, I get a TypeError, saying that there are no render and logIn methods (in theory, Passport should give it). The above method is made for a POST request.
Has anyone implemented something like this? Where should the render and logIn methods come from?
