Definition​

This ObservablePipe is a passthrough to log the state of an Observable. It is useful to debug your Observables and improve sometimes the performances.

Example​

Debug the state of on Observable​

const subscribe = pipe$$(interval(1000), [
  debug$$$('interval'),
  scan$$$(_ => (_ + 1), 0),
]);

const unsubscribe = subscribe(() => {

});

setTimeout(unsubscribe, 2500);

Output:

[ SUB ] interval
[VALUE] interval 0
[VALUE] interval 1
[UNSUB] interval
