This one area where using something like ngrx/store for state management can really become powerful, because most components can adopt an OnPush strategy, and ngrx will dispatch new references when data changes. Angular Preloading Strategy is yet another way to speed up the load time of the Angular Apps. The Angular router is a marvel of software engineering. 3 min read.
