Dynamically tracks mutations and listens for click and seen events.
DOM Event Tracker uses IntersectionObserver and MutationObserver for tracking click and seen events.
Whenever an element is visible in the users screen it fires seen event.
Whenever user clicks an item, it fies click event.
npm install dom-event-tracker
You can also clone repository and build.
git clone [email protected]:Trendyol/dom-event-tracker.git && cd dom-event-tracker
npm install
npm run build
- Add
data-tracker-rootattribute to root element. Root element is being tracked for mutations. - Add tracking attributes to elements that you want to track
data-tracker="seen:seenEventName click:clickEventName". - Start Tracker
window.Tracker.init((eventName, eventType, element) => {
//Report your event
GoogleAnalytics.fireEvent(eventName);
});<html>

</html>Whenever an element is visible in the users screen it fires seen event. IntersectionObserver without threshold.
Whenever callback returns
true, seen event won't be fired for that element. Otherwise it will always fire seen event. This means almost each scroll
Whenever user clicks an item, it fires click event.
Uses event bubbling for listening click events.
Whenever user clicks an item, it fires click event.
Uses event capturing for listening click events.
You can provide root callback for async initialize.
<div data-tracker-root="onTrackerLoaded">
<div data-tracker="seen:seenItem"></div>
</div>
<script>
function onTrackerLoaded(e){
GoogleAnalytics.event(e);
}
</script>
<script src="cdn://tracker.min.js" defer></script>You can also call init manually
<div data-tracker-root="">
<div data-tracker="seen:seenItem"></div>
</div>
<script src="cdn://tracker.min.js"></script>
<script>
window.Tracker.init((e) => GoogleAnalytics.event(e));
</script>function callbackHandler(eventName, eventType, element){
}
