This repository curates resources for understanding and utilizing service workers. Service workers enable progressive web apps (PWAs) to function offline, provide push notifications, and offer a more app-like experience. Service workers act as a programmable network proxy between the web app, browser, and network, enhancing performance and reliability. The primary technology is the Service Worker API, a JavaScript-based API supported by modern browsers.
