NB: You can use the canLoad guard to prevent feature module from loading if the user is not authorized to access a route. You can use canLoad guard alongside canActivate and canActivateChild guards which prevent
在路由模块中导入并配置 import{PreloadingStrategyService}from'../preloading-strategy.service';// ...{path:'',loadChildren:()=>import('./user/user.module').then(m=>m.UserModule),data:{preload:false}},// ...{preloadingStrategy:PreloadingStrategyService,relativeLinkResolution:'legacy'}// ... 其...
To tell which modue should be preloaded. Then provide a custom loading strategy: import {PreloadingStrategy, Route} from "@angular/router"; import {Observable} from"rxjs"; export classPreloadSelectedModuledsListimplements PreloadingStrategy { preload(route: Route, load: Function): Observable<any>{re...
UpgradeModule 将在每一次离开 Angular zone 时调用 AngularJS 的 $rootScope.$apply()。这样也就同样会在每个事件之后触发 AngularJS 的变更检测。 在实践中,你不用在自己的代码中调用 $apply(),而不用管这段代码是在 AngularJS 还是 Angular 中。 UpgradeModule 都替你做了。你仍然可以调用$apply(),也就是...
Preloading all modulesis quite an extreme approach and might not always be desirable. For instance, you don't want to preload lazy routes a user might not even have access to. Therefore, in this lesson we're going to have a look at how to define a custom preloading strategy in Angular....
// "moduleResolution": "node", /* Specify module resolution strategy: 'node' (Node.js) or 'classic' (TypeScript pre-1.6). */ // "baseUrl": "./", /* Base directory to resolve non-absolute module names. */ // "paths": {}, /* A series of entries which re-map imports to lo...
创建特性模块:使用Angular CLI创建特性模块,例如ng generate module featureName --route featureName。 配置路由:在app-routing.module.ts中,使用loadChildren属性来指定懒加载的模块。 typescript // app-routing.module.ts const routes: Routes = [ { path: 'featureName', loadChildren: () => import('./fea...
在loading写入根组件,这里有两点注意。 ChangeDetectionStrategy 组建变化的检查策略,以上述代码为例,当为ChangeDetectionStrategy设置OnPush时,组件就不会一直进行脏检查了,而是当输入属性变化时,才会启动检查策略,这里值的注意的是,这个输入的对象需要变化成一个新对象时,组件才会进行检查,而不是仅仅是改变属性的值,或者...
Lazy loading routes Now the current way our routes are setup makes it so they are included in the same chunk as the root app.module, which is not ideal. Instead, the router has a setup that allows the components to be isolated to their own chunks. ...
- `urlHandlingStrategy` has been removed from the Router public API. This should instead be configured through the provideRouter or RouterModule.forRoot APIs. - The following Router properties have been removed from the public API: - canceledNavigationResolution ...
