 > :warning: **This plugin will stop receiving feature requests. I will only spend time for important bug fixes**. Google moved from analytics.js to its new gtag.js library and I've created a new plugin called [vue-gtag](https://github.com/MatteoGabriele/vue-gtag). I suggest you to start using that one if you are about to create a new project.

 # vue-analytics
 
 Vue plugin for Google Analytics

 ## Why should I use it?
