Usage Examples

​
Basic Example

import { interval, fromEvent, skipUntil } from 'rxjs';

const intervalObservable = interval(1000);
const click = fromEvent(document, 'click');

const emitAfterClick = intervalObservable.pipe(
  skipUntil(click)
);

emitAfterClick.subscribe(value => console.log(value));
// Starts emitting after first click
  • skip - Skips first N values
  • skipLast - Skips last N values
  • skipWhile - Skips while condition is true
  • takeUntil - Takes values until another Observable emits
