AngularJS Include scripts based on current route

The AngularJS approach is to load them all beforehand. You could probably do something like

$routeProvider
  .when('/home',
    {
        templateUrl: '/app/views/home.html',
        resolve: resolveController('/app/controllers/homeController.js')
    });

And then resolveController would return a promise.It would load the scriptwith the controller and resolve the promise once the load is complete. Something like

app.config(['$routeProvider',
    function($routeProvider) {
        var resolveController = function(path) {
            var deferred = $q.defer();
            var script = document.createElement('script');
            script.src = path;
            script.onload = function() {
                $scope.$apply(deferred.resolve());
            };
            document.body.appendChild(script);
            return deferred.promise;
        };
        $routeProvider.when('/home', function() { /*...*/ } );
    }
);

There could be syntax errors as I haven't even tried this, but this is what I would probably try if I wanted to do it.
