Angular 5 模块和路由

Question

我知道如何配置路由来加载组件，如下所示：

//app.module.ts
const appRoutes: Routes = [
    {path: '', component: HomeComponent},
    {path: 'login', component: LoginComponent},
}

我只是想知道我们是否可以将路由关联到一个模块，该模块包含指向一组组件的子路由。类似于名为Dashboard 的模块，它在加载与其关联的组件之前执行某些检查。比如：

• 首页
• 登录
• 仪表板
  • 索引
  • 文章

然后做：

//dashboard.module.ts
const appRoutes: Routes = [
    {path: 'dashboard', component: DashboardIndexComponent},
    {path: 'dashboard/articles', component: DashboardArticleComponent},
}

我很想知道我对这个概念的理解是如何不正确的，或者如果我对这个概念的理解不正确，推荐的方法是什么？

谢谢。

Answer 1

是的，您可以构建所谓的功能模块并将该功能的路由添加到该模块。在您的示例中，它将是一个“仪表板”功能模块。然后，您可以选择延迟加载该模块。有关更多信息和示例，请参阅：angular.io/guide/feature-modules

我这里有一个更完整的例子：https://github.com/DeborahK/MovieHunter-routing

在我的示例中，“电影”是功能模块。

这里以电影模块的代码为例：

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';

import { SharedModule } from '../shared/shared.module';
import { ReactiveFormsModule } from '@angular/forms';

import { MovieListComponent } from './movie-list.component';
import { MovieDetailComponent } from './movie-detail.component';
import { MovieEditComponent } from './edit/movie-edit.component';
import { MovieEditInfoComponent } from './edit/movie-edit-info.component';
import { MovieEditTagsComponent } from './edit/movie-edit-tags.component';

import { MovieService } from './movie.service';
import { MovieParameterService } from './movie-parameter.service';
import { MovieResolver } from './movie-resolver.service';
import { MovieEditGuard } from './edit/movie-edit-guard.service';
import { MovieSearchComponent } from './search/movie-search.component';
import { MovieEditReactiveComponent } from './edit/movie-edit-reactive.component';

export const movieRoutes: Routes = [
  { path: '', component: MovieListComponent },
  { path: 'search', component: MovieSearchComponent },
  {
    path: ':id',
    resolve: { movie: MovieResolver },
    component: MovieDetailComponent
  },
  {
    path: ':id/editReactive',
    resolve: { movie: MovieResolver },
    component: MovieEditReactiveComponent
  },
  {
    path: ':id/edit',
    resolve: { movie: MovieResolver },
    canDeactivate: [ MovieEditGuard ],
    component: MovieEditComponent,
    children: [
      { path: '', redirectTo: 'info', pathMatch: 'full' },
      { path: 'info', component: MovieEditInfoComponent },
      { path: 'tags', component: MovieEditTagsComponent }
    ]
  }
];

@NgModule({
  imports: [
    SharedModule,
    ReactiveFormsModule,
    RouterModule // For lazy loading, use this instead: RouterModule.forChild(movieRoutes)
  ],
  declarations: [
    MovieListComponent,
    MovieDetailComponent,
    MovieEditComponent,
    MovieEditInfoComponent,
    MovieEditTagsComponent,
    MovieEditReactiveComponent,
    MovieSearchComponent
  ],
  providers: [
    MovieService,
    MovieParameterService,
    MovieResolver,
    MovieEditGuard
  ]
})
export class MovieModule { }
