Keynote: Progressive Web Apps
summary
Progressive Web Apps claim to combine web distribution with native features by using an HTTPS-hosted JSON manifest and a controllable service worker to enable offline caching, background refresh and push. Tools shown include PWA Builder, Google Workbox, Mozilla’s ServiceWorker Cookbook and Lighthouse; measured wins: Forbes cuts mobile load from 6.5s to 2.5s with +10% impressions, Twitter Lite uses ~90% less data than the native app. PWAs install by use, update atomically, and work on low-end devices and flaky networks.
