Capturing every event can get chatty. Batching events with a throttled buffer in RxJS lets you capture all of those events and use them responsibly without overloading a subscriber downstream.
var Observable = Rx.Observable; var button = document.getElementById('btn'); var clicks = Observable.fromEvent(button,'click'); var source = clicks.scan(0, function(x){ return x+1; }) .buffer(clicks.debounce(1000)) .forEach(function(x){ sendValues(x); }); function sendValues(arr) { var pre = document.createElement('pre'); pre.innerHTML = JSON.stringify(arr); document.querySelector('#results') .appendChild(pre); }
