Configures initial navigation to start before the root component is created.

The bootstrap is blocked until the initial navigation is complete. This should be set in case you use server-side rendering, but do not enable hydration for your application.

Basic example of how you can enable this navigation behavior:

const appRoutes: Routes = [];
bootstrapApplication(AppComponent,
  {
    providers: [
      provideRouter(appRoutes, withEnabledBlockingInitialNavigation())
    ]
  }
);
