Comprehensive Faqs Guide: Advanced Service Worker Techniques: Background Sync, Push Notifications, and Data Pre-caching
Service Worker Basics and Lifecycle What is a service worker, and how does it function within a Progressive Web App (PWA)? A service worker is a JavaScript file that runs in the background of a web application, separate from the main web page. It acts as a programmable proxy between the web application, the network, and the browser cache.
