ngrx-effects

I'm creating an Ngrx Angular 2 app and was trying to get my http calls to continue polling after a time interval. I have seen the use of the interval() function, but in case of Ngrx, when service calls are done inside @Effect() , it gives an error. Please advise: @Injectable() export class TasksEffects { constructor( private actions$: Actions, private TS: TaskService ){} @Effect() onLoadTasksLoadTasks$: Observable<Action> = this.actions$.ofType(tasksActions.ActionTypes.LOAD_TASKS) .switchMap(() => { return this.TS.index() .map((res) => new tasksActions.LoadTasksSuccessAction(res.json()))

I am using @ngrx/effects 4.1.1. I have an effect that returns an empty observable like this: @Effect() showDialog$: Observable<Action> = this .actions$ .ofType( ActionTypes.DIALOG_SHOW ) .map( ( action: DialogAction ) => action.payload ) .switchMap( payload => { this.dialogsService.showDialog( payload.className ); return empty(); } ); I am trying to write a unit test following these guidelines that will test that the effect yields an empty observable. I have this: describe( 'DialogEffects', () => { let effects: DialogEffects; let actions: Observable<any>; const mockDialogService = { showDialog

Before lettable operator, I did a helper to modify debounceTime method, so it uses a TestScheduler: export function mockDebounceTime( scheduler: TestScheduler, overrideTime: number, ): void { const originalDebounce = Observable.prototype.debounceTime; spyOn(Observable.prototype, 'debounceTime').and.callFake(function( time: number, ): void { return originalDebounce.call( this, overrideTime, scheduler, ); }); } So the test of the following Observable was easy: @Effect() public filterUpdated$ = this.actions$ .ofType(UPDATE_FILTERS) .debounceTime(DEFAULT_DEBOUNCE_TIME) .mergeMap(action => [...])
