NgStoreReferenceAsyncSignalGroupfinish

finish Property Readonly

An emitter that triggers when the asynchronous action’s entire lifecycle is completed, whether it ends in success or failure. This emitter does not carry any payload (void), as it simply serves as a notification that the process is fully complete

API

readonly finish: Emitter<void>;

Example

import {switchMap} from 'rxjs';
import {transmit} from '@bitfiber/rx';
import {asyncSignalGroup} from '@bitfiber/ng/rx';
 
// Creates an asynchronous group
const group = asyncSignalGroup<number, string[], Error>((group, {launch, finish}) => {
  launch
    // Sets an effect to be triggered on new launch emissions
    .effect(
      switchMap(page => apiService.get(`api/get?page=${page}`)
        // 'transmit' operator takes either data or an error and transmits it to the `success`
        // or `fail` emitter of the group, respectively
        .pipe(transmit(group))),
    );
 
  finish
    // Performs a tap callback each time the request either fails or succeeds
    .tap(() => console.log('Request has been finished'));
});
