Tracking page views on regular websites is pretty easy: you just add a tracking code to every page and done! Every time a visitor clicks an internal link, a browser window refreshes, and a new page view hit is caught by the Google Analytics.

But when it comes to single page websites (or web applications), the default tracking stops working. Regardless of what does the user/visitor does on your website, only one page view is tracked.
