Showing what I added for Express Authentication course

Hello Treehouse, I've done the Express Authentication and it was absolutely perfect but there was one thing I desired to do and that was be able to search for a users profile based on the given id in the url so I am here to share the snippet if anyone else wants to try it out :)

// GET /profile/:id
router.get('/profile/:id?', function(req, res, next){
  var id = req.params.id;
  User.findById(id)
    .exec(function(err, user){{
      if (err) {
        return next(err);
      } else {
        return res.render('profile',{
          title: user.name,
          name: user.name,
          favorite: user.favoriteBook
        })
      }
    }});
});

Basically I am taking the :id and putting it into a variable. You can name :id anything but the req.params.name must be the name you set for the :name. Now all you do is grab a users id and put it into the url after the /profile/ID and it will show the results on that user whether you are signed in or not :)
