Angular 2 - Lifecycle hooks for lazy loaded modules
The constructor of the lazy loaded module should do that
@NgModule({...})export class MyLazyModule { constructor(/* service injection here if required */) { console.log('lazy module loaded'); }}
There are two router events that you can use: RouteConfigLoadStart
and RouteConfigLoadEnd
. Also you can use LoadChildrenCallback
. These might not do exactly what you want, but still can be helpful.
Also you can use the following trick:
@NgModule({ imports : [BrowserModule, FormsModule, RouterModule, ROUTING], providers : [ {provide: CustomService, useClass: CustomService}, ... ]})export class AppModule implements OnInit{ //force CustomService service creation or inject other app service, // so use can use it to fire event or do smth. constructor(handler:CustomService) { console.log('handler', handler); handler.fire('module created'); }}
