RAII Pattern For API Controllers on Node.js

function HomeController (config, server) {
 this.config = config;
 this.server = server;

 server.get( // restify style route logic
 {
 'name': 'Home',
 'path': '/',
 'version': '0.0.1'
 },
 this.getHomePage.bind(this)
 );
}

HomeController.prototype.getHomePage = function (req, res, next) {
 res.json({'message': 'This is just a quick test'});
 next();
};

module.exports = exports = HomeController;

The controller's constructor accepts a configuration and server object (adapt to Express & Restify as needed), and uses them to wire up the controller's routes to handler methods defined on the controller class.
