How to implement RouteReuseStrategy shouldDetach for specific routes in Angular 2

In Angular 2, the RouteReuseStrategy interface allows developers to control the behavior of route caching and reuse. By implementing this interface, you can customize which routes should be cached and when they should be re-rendered.

To achieve your goal of storing the "documents" route but not the "documents/:id" route, you will need to implement the shouldDetach method in your RouteReuseStrategy class. This method takes an ActivatedRouteSnapshot as input and returns a boolean indicating whether or not the route should be stored for future reuse.

Here's an example implementation of shouldDetach that stores only the "documents" route and discards all other routes:

<code class="typescript">import { RouteReuseStrategy, ActivatedRouteSnapshot } from '@angular/router';

export class CustomRouteReuseStrategy implements RouteReuseStrategy {
  shouldDetach(route: ActivatedRouteSnapshot): boolean {
    return route.routeConfig?.path === 'documents';
  }

  // Other implementation details omitted for brevity
}</code>

Remember to provide your custom strategy in your app's module:

<code class="typescript">@NgModule({
  // ...
  providers: [
    { provide: RouteReuseStrategy, useClass: CustomRouteReuseStrategy },
  ],
})
export class AppModule {}</code>

With this strategy in place, Angular will cache the "documents" route when navigating away from it. When you navigate back, it will use the cached route component instead of recreating a new instance, ensuring a faster and more seamless transition.
