Welcome to the second issue of PWA newsletter!

This issue is all about diving deep.

First, Dean Hume guides us through an assortment of advanced PWA tips. Then, Matt Gaunt picks up where he leaves off and takes us through the ins and outs of testing service workers (even going as far as emulating certain events, such as fetching files).

Our last link is to, a fantastic collection of progressive web apps, from hobby projects to production builds. Many have source code available—if I ever need PWA inspiration (or, more likely, a little help), this is my first stop.

If you have any questions, comments, or just general musings, hit the reply button above and let me know. And if you're reading this online, enter your email above to stay up to date on the world of PWA's.
