How to create a RxJS buffer that groups elements in NodeJS but that does not rely on forever running interval?

Question

I\'m capturing events from an application using Rx.Observable.fromEvent in a NodeJS. These are sent to another server using request (https://www.npmjs.com/pack

Answer 1

A proposed implementation, using the delay operator :

function emits(who){
  return function (x) { console.log([who, "emits"].join(" ") + " " + x + " click(s)");};
}

var source = Rx.Observable.fromEvent(document.body, 'click');
console.log("running");

var delayedSource$ = source.delay(1200);

var buffered$ = source
     .buffer(function () { return  delayedSource$;}).map(function(clickBuffer){return clickBuffer.length;})

buffered$.subscribe(emits("buffer"));
