Reading Resilient Web Design
A must-read book by Jeremy Keith for all Web Workers: https://resilientwebdesign.com
I found out about this book through Marc Thiele when he mentioned it in his latest Beyond Tellerrand newsletter.
At the time of writing this I'm still reading through the first chapters and after finishing only the introduction I was already convinced that this book is highly recommended for everyone working in the Web industry.
The website itself is also an interesting example of a Progressive Web App with offline support and all the features a modern web app should have today.
So go read Resilient Web Design right now.
