I am building a registration form (passport-local as authentication, forms as form helper).

Because the registration only knows GET and POST I would like to do the whole handling in one function.

With other words I am searching after something like:

```
exports.register = function(req, res){
    if (req.isPost) {
       // do form handling
    }
    res.render('user/registration.html.swig', { form: form.toHTML() });
};

```
