PWA Fundamentals: websites with superpowers
summary
Claims that browser support is excellent since 2015 and that PWAs can feel native get tested with concrete code: a demo PWA uses a Manifest File, an npm icon generator (npm run generate), registered Service Workers with install/activate/fetch handlers, static v1→v2 cache versioning, dynamic cache plus an indexDB store for JSON, and an offline.html fallback. Measured load drops from ~145ms to ~59ms. Add‑to‑home handling, skipWaiting update flow, and periodic/background sync notes are implemented or shown as working or experimental.
