AMP to PWA
<amp-install-serviceworker>. This takes an AMP page and allows it to install a service worker so a user shifts to a PWA when they click. This gives the fast initial page load of an AMP page and prepares the browser to make the second page load just as fast.
Let’s say someone shares a PWA page with a friend. We’d want the friend to have a fast page load, but if they go to a PWA page as the first experience, they won’t get the acceleration via the service worker. So we could do some detection at the page load to see if the service worker is available, if not, move to the AMP experience of that page.
I just found out about the Dive Into HTML5 tutorial. It’s downright amazing. I wish all specs were so carefully described. Don’t miss the first chapter on the history of standards creation. It gives you a good understanding of why the HTML standards are quirky and why HTML5 is progressing the way it is.
I especially like the way they test your browser for its ability to handle the various components you are reading about. Take an hour or so to go through this tutorial. It’s the best read you’ll have for the week.
Another good tutorial is The Best HTML5 Slides Ever, but you’ll need to view it in Safari. It doesn’t work well in the standard Firefox and forget about IE.
