Angular Material 使用延迟加载模块

Angular Material with Lazy Loading Module

我已经找到了看起来相似但对我没有帮助的东西。

我的问题是,我有延迟加载模块。应用-routing.module.ts

const routes: Routes = [
  {path: '', redirectTo: '/home', pathMatch: 'full'},
  {path: 'home', loadChildren: () => import('./home/home-routing.module').then(m => m.HomeRoutingModule)},
  {path: '**', loadChildren: () => import('./error/error-routing.module').then(m => m.ErrorRoutingModule)}
];

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

家庭路由模块看起来像:

@NgModule({
  imports: [RouterModule.forChild(
    [
      {path: '', component: NavigationComponent},
    ]
  )]
})
export class HomeRoutingModule {
}

导航组件只是为 sidenav 生成的 material 架构。 https://material.angular.io/guide/schematics#navigation-schematic

但结果我得到:

Error: src/app/home/navigation/navigation.component.html:1:1 - error NG8001: 'mat-sidenav-container' is not a known element:

  1. If 'mat-sidenav-container' is an Angular component, then verify that it is part of this module.
  2. If 'mat-sidenav-container' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.

将 sidenav 代码移动到 app.component.html 一切正常。

我家模块是这样的

@NgModule({
  declarations: [NavigationComponent],
  imports: [
    CommonModule,
    HomeRoutingModule,
    LayoutModule,
    MatToolbarModule,
    MatButtonModule,
    MatSidenavModule,
    MatIconModule,
    MatListModule
  ]
})
export class HomeModule { }

不知道我哪里做错了吗?

谢谢

要导入延迟加载模块,您需要导入包含组件声明的主模块,以及这些组件所需的模块:

在您的应用中-routing.module

//home.module and HomeModule, instead of HomeRoutingModule
{path: 'home', loadChildren: () => import('./home/home.module').then(m => 
m.HomeModule)}

在你的homeRoutingModule中,你需要导出RouterModule:

 @NgModule({
 imports: [RouterModule.forChild(
   [
     {path: '', component: NavigationComponent},
   ]
 )],
 exports: [RouterModule]
 })

最后,在您的 HomeModule 中,导入您的 HomeRoutingModule:

imports: [
 ...
 HomeRoutingModule,
 ....

]
