In Angular 14, we introduced the `loadComponent` API for a `Route` to allow lazy loading of a routed component in addition to the existing `loadChildren` which allows lazy loading of child routes. As a result, the `preload` method of the `PreloadingStrategy` needs to sometimes be called even when there is a `canLoad` guard on the `Route`. `CanLoad` guards block loading of child routes but _do not_ block loading of the component. This change updates the conditional checks in the internal preloader to skip calling the `PreloadingStrategy.preload` when there is only a `loadChildren` callback with a `canLoad` guard an no `loadComponent`. In this case, the callback passed to the `preload` method is already effectively a no-op so it's not necessary to call it at all. resolves angular#47003

In Angular 14, we introduced the
loadComponent
API for aRoute
toallow lazy loading of a routed component in addition to the existing
loadChildren
which allows lazy loading of child routes. As a result,the
preload
method of thePreloadingStrategy
needs to sometimes becalled even when there is a
canLoad
guard on theRoute
.CanLoad
guards block loading of child routes but do not block loading of the
component.
This change updates the conditional checks in the internal preloader to
skip calling the
PreloadingStrategy.preload
when there is only aloadChildren
callback with acanLoad
guard an noloadComponent
.In this case, the callback passed to the
preload
method is alreadyeffectively a no-op so it's not necessary to call it at all.
