The `tap` operator is designed solely for such side-effects to - * help you remove side-effects from other operations. - * - * For any notification, next, error, or complete, `tap` will call the appropriate callback you have provided to it, via a function - * reference, or a partial observer, then pass that notification down the stream. - * - * The observable returned by `tap` is an exact mirror of the source, with one exception: Any error that occurs -- synchronously -- in a handler - * provided to `tap` will be emitted as an error from the returned observable. - * - * > Be careful! You can mutate objects as they pass through the `tap` operator's handlers. - * - * The most common use of `tap` is actually for debugging. You can place a `tap(console.log)` anywhere - * in your observable `pipe`, log out the notifications as they are emitted by the source returned by the previous - * operation. - * - * ## Examples - * - * Check a random number before it is handled. Below is an observable that will use a random number between 0 and 1, - * and emit `'big'` or `'small'` depending on the size of that number. But we wanted to log what the original number - * was, so we have added a `tap(console.log)`. - * - * ```ts - * import { of, tap, map } from 'rxjs'; - * - * of(Math.random()).pipe( - * tap(console.log), - * map(n => n > 0.5 ? 'big' : 'small') - * ).subscribe(console.log); - * ``` - * - * Using `tap` to analyze a value and force an error. Below is an observable where in our system we only - * want to emit numbers 3 or less we get from another source. We can force our observable to error - * using `tap`. - * - * ```ts - * import { of, tap } from 'rxjs'; - * - * const source = of(1, 2, 3, 4, 5); - * - * source.pipe( - * tap(n => { - * if (n > 3) { - * throw new TypeError(`Value ${ n } is greater than 3`); - * } - * }) - * ) - * .subscribe({ next: console.log, error: err => console.log(err.message) }); - * ``` - * - * We want to know when an observable completes before moving on to the next observable. The system - * below will emit a random series of `'X'` characters from 3 different observables in sequence. The - * only way we know when one observable completes and moves to the next one, in this case, is because - * we have added a `tap` with the side effect of logging to console. - * - * ```ts - * import { of, concatMap, interval, take, map, tap } from 'rxjs'; - * - * of(1, 2, 3).pipe( - * concatMap(n => interval(1000).pipe( - * take(Math.round(Math.random() * 10)), - * map(() => 'X'), - * tap({ complete: () => console.log(`Done with ${ n }`) }) - * )) - * ) - * .subscribe(console.log); - * ``` - * - * @see {@link finalize} - * @see {@link TapObserver} - * - * @param observerOrNext A next handler or partial observer - * @param error An error handler - * @param complete A completion handler - * @return A function that returns an Observable identical to the source, but - * runs the specified Observer or callback(s) for each item. - */ -export function tap( - observerOrNext?: Partial> | ((value: T) => void) | null, - error?: ((e: any) => void) | null, - complete?: (() => void) | null -): MonoTypeOperatorFunction { - // We have to check to see not only if next is a function, - // but if error or complete were passed.
