module.run() equivalent in Angular 2

I wonder if there’s something like angular.module().run() in Angular 2. Angular 2 doesn’t have config() and run() anymore (which is good), but I think there are still some cases where we want to execute some code, once everything inside a component is compiled. Something that is only initially executed.

I’m currently playing with the instance of ComponentRef that we get from bootstrap() a la:

bootstrap(MyComponent).then((ref) => {
  let app = ref.instance;

  app.run();
});

Whereas run() is a method that needs to be executed once everything inside MyComponent is compiled. I also tried using onAllChangesDone but it seems this is executed several times per second and not only once.

You can put work into the constructor of the module.

Use of then on ComponentRef should be the right approach.

bootstrap(MyComponent).then((ref) => {
  let app = ref.instance;

  app.run();
});

What specifically is not working?
