Run it

$ node -r index.js
> ArticlesController.hello();

  static hello() {
    return 'Hello Fred!';
  }
}

And call again

$ node -r index.js
> ArticlesController.hello();
Hi!
> ArticlesController.hello();
Hello Fred!

Cache classes

You can set cache_classes with true to cache classes. It will cause no class will be autoloaded

Name scope

You can also specify a name scope e.g.

$ mkdir app/controllers/my_scope
$ touch app/controllers/my_scope/one_class.js

MyScope.OneClass // will cause autoload one_class.js

Eager load

Set cache_classes and eager_loader with true, classes will be autoloaded before call it
