Компонент входа в систему занимает много времени, чтобы загрузить изначально в Angular 4

Question

Как вы видите, у вас есть 5 в основном модуле. Там, когда вы пытаетесь загрузить логин, загрузка занимает 14 секунд. Я думаю, что компонент входа ожидает компонент fulllayout.

Может ли кто-нибудь посоветовать, если я правильно обработал ленивую загрузку. Если нет, как это сделать здесь?

Это совсем не ленивая загрузка!

Вот пример, где модуль PagesModule имеет ленивую загрузку:

в вашем app-routing-module.ts:

const routes : Routes = [
  {
    path: 'pages',
    loadChildren: 'app/pages/pages.module#PagesModule',
  }, {
    path: 'auth',
    component: AuthComponent,
    children: [
      {
        path: '',
        component: LoginComponent,
      }, {
        path: 'login',
        component: LoginComponent,
      }, {
        path: 'register',
        component: RegisterComponent,
      }, {
        path: 'reset-password',
        component: ResetPasswordComponent,
      },
    ],
  },
]

в ваших страницах. модули:

@NgModule({
  imports: [
    PagesRoutingModule,  <----
    ...],
 declarations:[...]
})

и в ваших страницах-routing-module.ts:

const routes: Routes = [
   {
    path: '',
    canActivate: [AuthGuard],
    component: PagesComponent,
    children: [
      {
        path: 'dashboard',
        component: DashboardComponent,
      }, {
        path: 'ui-features',
        loadChildren: './ui-features/ui-features.module#UiFeaturesModule',
      }, {
        path: 'components',
        loadChildren: './components/components.module#ComponentsModule',
      }
   ]}
]
