How do you test a service worker, anyway?

https://jeffy.info/2022/08/25/testing-a-service-worker.html

if you're writing a service worker from scratch, if you're using one of Workbox's more exotic plugins or custom strategies, or if your service worker's behavior is particularly important to your overall user experience, developing a test suite dedicated to your service worker can give you an important peace of mind.

   Who still thinks writing a Service Worker for basic features (performance with cache, offline fallback) is cumbersome?

   Using #Workbox recipes make it so easy!

   Here's the Service Worker for https://pack11ty.dev 😍

   Tried to write a fresh new Service Worker with #Workbox 5 and #Rollup (first time ever), almost copy/pasted from what @jeffposnick did in https://github.com/GoogleChromeLabs/so-pwa but I get a strange error reporting mixed content… 😥

3. How much data should my Service Worker put upfront in the offline cache?

   I love when Web site/apps work even when I'm offline. I've made my SVG game esviji work offline thanks to appcache just after attending Jake Archibald conference about why Application Cache is a Douchebag during the 2012 edition of the Paris Web conference. Fortunately, we have now Service Workers (in some browsers), which gives us more control over this kind of cache for offline browsing. But as Uncle Ben says, “With Great Power Comes Great Responsibility”.
