Summary

Build Progressive Web Apps that work offline, install like native apps, and deliver fast, reliable experiences.

  • Requires three core pillars: HTTPS (or localhost), a service worker with fetch handler, and a web app manifest with metadata and icons (192px, 512px, maskable)
  • Supports five caching strategies (Cache First, Network First, Stale While Revalidate, Network Only, Cache Only) matched to resource types; Workbox simplifies implementation with precaching, expiration, and background sync
  • Enables offline functionality through service worker registration, offline fallback pages, and background sync for queuing actions when disconnected
  • Includes app-like features: install prompts, standalone mode detection, push notifications, and share target integration for native-like behavior
