I have had an excuse for awhile that since I lack a recent Mac, that I can't create a mobile app for an iPhone. A friend pointed me at Service Workers as a solution to my problem but I did not get it at the time. Today the same guy pointed me at a talk by Jake Archibald and it all clicked. I get it now.
- Your First Progressive Web App
- Service Workers: An Introduction
- Service Worker - GitHub
- Service Worker API - MDN
- Service Workers - W3C Draft
I have much work to do.
