🚀 Dom Event Tracker!
Dynamically tracks mutations and listens for click and seen events.
DOM Event Tracker uses IntersectionObserver and MutationObserver for tracking click and seen events.

});Example
<html>
<head></head>
<body>
<div class="container" data-tracker-root>
<div>
<div class="info-box" data-tracker="seen:infoBoxSeen"></div>
</div>
<div class="help-button" data-tracker="click:helpButtonClicked"></div>
<div class="info-button" data-tracker="click-capture:infoButtonClicked"></div>
</div>
<script>

</script>
</body>
</html>Event Types
Seen (seen:eventName)
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
Click (click:eventName)
Whenever user clicks an item, it fires click event.
Uses event bubbling for listening click events.
ClickCapture (click-capture:eventName)
Whenever user clicks an item, it fires click event.
Uses event capturing for listening click events.
