// app.module.ts
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    ContactsModule,
    UtilsModule.forRoot()
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

// ===============================
// app-routing.module.ts

const routes: Routes = [
  { path: 'home', loadChildren: () => import('./features/home/home.module').then(m => m.HomeModule) },
  { path: 'catalog', loadChildren: () => import('./features/catalog/catalog.module').then(m => m.CatalogModule) },
  // IL PROBLEMA È QUI! Non carica questa pagina
  { path: 'welcome', loadChildren: () => import('./features/welcome/welcome.module').then(m => m.WelcomeModule) },
  /*{ path: 'contacts', loadChildren: () => import('./features/contacts/contacts.module').then(m => m.ContactsModule) }*/
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }
