ANALYZE_FOR_ENTRY_COMPONENTS

This token can be used to create a virtual provider that will populate the entryComponents fields of components and ng modules based on its useValue. All components that are referenced in the useValue value (either directly or in a nested array or map) will be added to the entryComponents property.

const ANALYZE_FOR_ENTRY_COMPONENTS: InjectionToken<any>;

使用说明

Example

The following example shows how the router can populate the entryComponents field of an NgModule based on the router configuration which refers to components.

// helper function inside the router function provideRoutes(routes) { return [ {provide: ROUTES, useValue: routes}, {provide: ANALYZE_FOR_ENTRY_COMPONENTS, useValue: routes, multi: true} ]; } // user code let routes = [ {path: '/root', component: RootComp}, {path: '/teams', component: TeamsComp} ]; @NgModule({ providers: [provideRoutes(routes)] }) class ModuleWithRoutes {}
