This Skill provides a robust service worker implementation to enable offline capability and reliable caching for Progressive Web Apps, improving reliability and performance in unreliable networks.
Register and load the service worker in your application startup: navigator.serviceWorker.register('/service-worker.js') Ensure the worker is included in the build and served at the correct path.

Offline caching for a Progressive Web App is implemented using a service worker that caches static assets and prerendered pages. It automatically handles cache versioning and cleanup during activation to ensure reliable content delivery.
Service worker cache versioning and updates are managed by enabling skip-waiting for immediate activation and performing automatic cache cleanup on activation. This approach minimizes downtime and removes outdated cached resources.
Dynamic content is handled differently from static assets by applying a network-first strategy. This balances content freshness with resilience, falling back to cached responses only when the network fails.
This service worker cannot be used for non-GET requests or extension URLs. It enforces GET-only requests and specifically caches 200 responses for non-extension URLs to ensure reliable offline behavior.
To register a service worker for PWA offline support, include it in your build and call navigator.serviceWorker.register('/service-worker.js') in your application startup. Ensure it is served at the correct root path.
You need an offline fallback in your web application to improve reliability and performance in unreliable networks. It ensures users can still access cached static assets and prerendered pages when connectivity drops.
