Service workers - beyond the cache

on YouTube ↗58m

" summary

Service workers power push notifications, background sync and more beyond simple caching, with concrete demos: a web SMS inbox uses VAPID keys and web-push libraries to subscribe and deliver pushes (Chrome/Firefox/Edge support ~75% of users), and an offline write is stored in IndexedDB then replayed by background sync (global support ~67%) — demo shows the queued message is sent when connectivity returns. Workbox is recommended for declarative queues; background fetch remains experimental.
