Package Exports

@rxjs-ninja/rxjs-utility

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@rxjs-ninja/rxjs-utility) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

import { fromEvent } from 'rxjs';
import { startWithTap, tapIf, tapOnSubscribe } from '@rxjs-ninja/rxjs-utility';

const inputObs$ = fromEvent(document, 'click').pipe(
  startWithTap(() => console.log('This will only fire once')),
  tapOnSubscribe(() => console.log('This will tab on every subscribe')),
  tapIf(
    (event) => event.target.id === 'some-div',
    () => console.log('This will tap if the user clicks on the target element'),
  ),
);

inputObs$.subscribe(); // This will only fire once, This will tab on every subscribe
inputObs$.subscribe(); // This will tab on every subscribe
