RouterPreloader

The preloader optimistically loads all router configurations to make navigations into lazily-loaded sections of the application faster.

class RouterPreloader implements OnDestroy { setUpPreloading(): void preload(): Observable<any> ngOnDestroy(): void }

说明

The preloader runs in the background. When the router bootstraps, the preloader starts listening to all navigation events. After every such event, the preloader will check if any configurations can be loaded lazily.

If a route is protected by canLoad guards, the preloaded will not load it.
