Google Analytics Plugin: Clean URLs

A plugin for Google Analytics to remove UTM query strings from URLs

This plugin is heavily inspired by Wistia's Fresh URL library but I wanted something more minimal so I've implemented its core functionality as a Google Analytics plugin.

Before:

https://example.com/article/?utm_source=twitter&utm_medium=tweet&utm_campaign=website&foo=bar

After:

https://example.com/article/?foo=bar

Install

npm install --save ga-clean-urls

Usage

The plugin must be loaded after the 'pageview' send so the UTM parameters are tracked correctly.

<script>
	ga( 'create', 'UA-XXXXX-Y', 'auto' );
	ga( 'send', 'pageview' );

	// Require the plugin after 'pageview' send
	ga( 'require', 'cleanUrls' );
</script>

<script async src="/path/to/ga-clean-urls/index.min.js"></script>

Browser support

IE10+.

The plugin uses history.replaceState to manipulate the URL, if the browser does not support history.replaceState then it shouldn't cause any problems but the URL will remain unchanged.
See http://caniuse.com/#feat=history for detailed browser support.
