title: Angular reload page when new version is deployed
body: <p>I have a SPA written in angular js. The problem now is that when I deploy a new version clients that already have the page open in the browser doesn't get the new version until they reload the browser.</p>
  
  <p>What I'm looking for is a way for the angular app to see that new files exist on disk and reload the page. Or show the user a toast that reload is needed.</p>
  
  <p>What is the best practice for this?</p>
  
  <p>Also, this is not a cache issue. I have a build tool that names all files with a hash. Like app-32ab432bb.js etc.</p>
