When you want to share some provider for app the children component, for example, NgrxStore:

export default const ROUTES = [
  // make an empty parent route
    {
        path: '', 
        providers: [
           importProvidersFrom(NgrxStore.forFeature(...))     
        ],
                               
        children: [
           {path: '', component: HomeCmp}, {path: 'admin', component: AdminCmp, providers: [{provide: AuthService, useClass: AdminAuthService}]}
        ]
    }
