# Service Worker Implementation

The [src/service-worker.ts](mdc:src/service-worker.ts) implements a Progressive Web App (PWA) service worker with the following features:

## Caching Strategy
- Caches all static assets (build files, static files, prerendered pages)
- Uses a network-first strategy for dynamic content
- Falls back to cached content when offline
- Cache versioning using build version

## Request Handling
- Only handles GET requests
- Caches successful (200) responses for non-extension URLs
- Implements skip waiting for immediate service worker updates

## Cache Management
- Automatically cleans up old caches during activation
- Creates new cache version on each deployment
- Efficiently manages static assets and dynamic content
