What are Service Workers?
Service Workers are JavaScript files that run in the background, separate from your web page. They enable features like offline functionality, push notifications, and background sync.
Key capabilities include:
- Offline Support: Cache resources to work without network
- Fetch Interception: Intercept and modify network requests
- Background Sync: Defer actions until connectivity returns
- Push Notifications: Receive messages even when page is closed
