  • ✅ Native app installation on iOS, Android, and Windows
  • ✅ Advanced caching strategies
  • ✅ Platform-specific optimizations

1. SERVICE WORKER CONFIGURATION ✅

Active Service Worker

File: /public/sw.js
Status: Active with Workbox integration

Key Features:

- skipWaiting: true         // Activate immediately
- clientsClaim: true        // Control all pages immediately
- precacheAndRoute: true    // Pre-cache all assets
- Offline fallback: enabled // Shows offline page when needed

Service Worker Registration

Registration Method: Automatic via Next.js PWA plugin
Register Option: register: true

2. CACHING STRATEGIES ✅

Cache Configuration

Resource Type Strategy Cache Name Max Age Max Entries
Google Fonts CacheFirst google-fonts 365 days 4
Fonts (static) StaleWhileRevalidate static-font-assets 7 days 4
Images StaleWhileRevalidate static-image-assets 24 hours 64
Next.js JS CacheFirst next-static-js 24 hours 64
API Routes NetworkFirst apis 24 hours 16
Document (fallback) Custom - - offline.html

Caching Behavior

Network First (APIs):

1. Serve cached version immediately
2. Fetch fresh version in background
3. Always get latest on refresh
