how to subscribe to action success callback using ngrx and effects
You can subscribe to actions in components as well:
[...]import { Actions } from '@ngrx/effects';[...]@Component(...)class SomeComponent implements OnDestroy { destroyed$ = new Subject<boolean>(); constructor(updates$: Actions) { updates$.pipe( ofType(PostActions.SAVE_POST_SUCCESS), takeUntil(this.destroyed$) ) .subscribe(() => { /* hooray, success, show notification alert etc.. */ }); } ngOnDestroy() { this.destroyed$.next(true); this.destroyed$.complete(); }}
Based on this:https://netbasal.com/listening-for-actions-in-ngrx-store-a699206d2210 with some small modifications, as since ngrx 4 there is no Dispatcher
anymore, but instead ActionsSubject
:
import { ActionsSubject } from '@ngrx/store';import { ofType } from "@ngrx/effects";subsc = new Subscription();constructor(private actionsSubj: ActionsSubject, ....) { this.subsc = this.actionsSubj.pipe( ofType('SAVE_POST_SUCCESS') ).subscribe(data => { // do something... });}ngOnDestroy() { this.subsc.unsubscribe();}
you need to have a selector that give you the latest post
this.latestPost$ = this.store.select(fromRoot.getPost);
then you can subscribe to this.latestPost$
observable and redirect to your new route assuming you have declared latestPost$: Observable<Post>;
in your component.
