Angular2 lazy loaded event

Question

I am using lazy loading with Angular2 and the PreloadAllStrategy .

I'm just wondering, is there any way to detect when all modules are preloaded and to preform an action when everything is preloaded?

I imagined there would be a router event similar to NavigationStart for this, such as RouteLoaded, but there is not.

Any ideas how this can be done?

The solution is to implement a SelectivePreloadingStrategy and to inject it to the component that needs to detect when a module is lazy loaded. This is described in the guide:
