You recommend using service worker as a cache for the app's ui shell. For that, the classic http cache is also an option, even in pretty old browsers and absence or failure of js. Maybe a box which discusses pros and cons of both would be helpful. For a static ui shell I would go for classic caching, but stand to be convinced why service worker is better.

Hi - thank you for your question!

I agree with you, the classic http cache is a great option for browsers that don't support Service Workers. In fact, HTTP cache and Service Workers go hand in hand.

I highly recommend reading this article by Jake Archibald about caching best practices.

It does a much better job of explaining this than I could in a single post.

Hope that helps - please let me know if you have any other questions!
