`importProvidersFrom` provides a bridge from the world of NgModule-based DI configuration to the new, "standalone" world of direct providers and environment injectors. Early user feedback suggested some confusion around where this function was supposed to be used, particularly around importing NgModule-based providers into standalone component `providers` arrays, which is not the intended use. This confusion is exacerbated by the fact that due to the unified `Provider` type, this kind of misconfiguration was happily accepted by the type system. This commit changes the return type of `importProvidersFrom` to wrap the returned providers in an opaque type that prevents them from being used in component provider contexts. This, together with stronger documentation around the purpose and functionality of `importProvidersFrom`, should address some of the above confusion. PR Close #45838
Angular Router
Managing state transitions is one of the hardest parts of building applications. This is especially true on the web, where you also need to ensure that the state is reflected in the URL. In addition, we often want to split applications into multiple bundles and load them on demand. Doing this transparently isn’t trivial.
The Angular router is designed to solve these problems. Using the router, you can declaratively specify application state, manage state transitions while taking care of the URL, and load components on demand.
