Using something like Mixpanel, you should be able to track anything that happens in your JavaScript code. However, it's not just a insert-a-script-and-sit-back solution; you have to be diligent about the actions you want to track and actually add code to track them as they happen.
I find mixpanel to be really good here also. Unfortunately, I quickly surpassed Mixpanel's 500 user free tier and it's been less useful ever since, but it still tracks events and has a lot of really helpful views on your data.
Recently, I've started homebrewing my own solution using Firebase (www.firebase.com). I've found it extremely straightforward and am enjoying having more control over my analytics data.
