PWA with React
summary
Step-by-step build with React covers installation, generating a manifest, and wiring a service worker caching strategy with concrete choices (cache‑first for assets, network‑first for API) and how that affects offline behavior. Implements push via VAPID / web‑push (or Firebase) with the subscription flow and server endpoint examples, shows update handling (skipWaiting, clients.claim, prompt UI) and measures improvements with Lighthouse scores and debugging tips so the demo actually registers, caches, receives a push, and updates live.
