Analytics 
This is a simple helper for triggering analytics events in the browser. It supports sending events to Google Analytics and Optimizely (via their official snippets). It's super tiny (510 bytes gzipped)!
Installation
You can get your own copy of Analytics using npm:
npm install @dosomething/analytics
Include the bundled dist/Analytics.js in your page, or require it using a module bundler.
Usage
You can manually send an event with Analytics.analyze('category', 'action', 'label').
You can also trigger events by setting data attributes on clickable items, or by using the global analyze() helper method in an inline script anytime after running Analytics.init():
<script src="dist/analytics.js"></script>
<script type="text/javascript">
Analytics.init();
</script>
<!-- Any click on this link will trigger a 'Link:Clicked:Click Me' event. -->
<a href="#" data-track-category="Link" data-track-action="Clicked" data-track-label="Click Me">Click Me!</a>
<!-- Any page load will trigger a 'Page:Loaded:Demo' event. -->
<script type="text/javascript">
analyze('Page:Loaded:Demo');
