Leverage Express 4 Router api

[gabzim]

Currently, routes.js exports a function that receives an app parameter, then it adds all the routes on this express app.

Express 4 now exports the router api, that way, you can do something like this:

In routes.js:

var api = express.Router();

api.route('/users')
    .post(users.create)
    .put(users.changePassword);

module.exports = api;

Why? Because then in server.js you can do:

app.use('/api', require('./lib/routes'))

This will respond to:

/api/users

Then say you want to upgrade your api. So you add v2.0. All you do is take that little line of code and change it to:

app.use('/api/v1', require('./lib/routes'))

And that's it. All your routes are now prefixed that way. It's more reusable. You can easily group your apis and then move them around as you see fit.
