var app = express();

var controllers = [
  {
    method: 'get',
    path: '/',
    exec: function(req, res) {
      res.send('hola mundo');
    }
  },
  {
    method: 'get',
    path: '/hola',
    exec: function(req, res) {
      res.send('mundo');
    }
  }
]

controllers.forEach(function(controller) {
  app[controller.method](controller.path, controller.exec)
});


http.createServer(app).listen(3000);
