PWA, Hidden Stories about future of the Web - II
summary
Only ~3% of sites run a service worker (2021) despite ~95% browser support, and about 85% of installs happen from browsers versus 67% via app stores, so adoption lags capability. Practical tools are service workers plus a web manifest, Web Vitals and the purple pattern (precache plus lazy load) to be fast and reliable. Platform APIs that actually work today include SMS Receiver, Contact Picker, File System Access, Web Bluetooth/USB and WASM; TWA packaging (Google Maps Go) and Starbucks/Twitter Lite prove PWAs can shrink install size and succeed.
