Progressive what apps
summary
Demonstration solves a 45 MB video blackout by replacing it with a <6 KB SVG animation and wireframes the caching: a service worker install/fetch flow that opens a named cache, uses cache.addAll with requests in no-cors mode, and falls back to network and cache-matching. Where service workers aren’t available it injects an iframe as an appcache iframe fallback. Shows tooling: a web-manifest crawler generator, web workers for CPU offload (virtual DOM achieving ~60 fps on a 2011 phone), and IndexedDB for multi‑GB offline storage.
