Keynote: Uncovering the secrets of Progressive Web Apps

on YouTube ↗44m

" summary

Progressive Web Apps claim offline installable apps via service workers and a web manifest, with current install support at about 50% now, 70% after Chrome 70, 75% when Mac support lands and ~95% on mobile; Android uses a web apk launcher that can silently update icons and capture all links in its scope; iOS limits per‑app storage (~50MB), can terminate PWAs on backgrounding causing two‑factor failures, and lacks shared storage for cross‑domain logins; tools to use include service workers, the beforeinstallprompt event, Chrome DevTools remote device port forwarding, and the Persistent Storage API.
