Can a Progressive Web App work offline?

Yes, a Progressive Web App (PWA) can work offline by utilizing various techniques such as caching, service workers, and the app shell model. PWAs are designed to be resilient and provide a seamless user experience even when there is limited or no network connectivity. By caching the app’s assets and data, a PWA can be accessed and interacted with offline. Service workers play a crucial role in enabling this functionality by intercepting network requests and providing cached responses. The app shell model allows for the quick loading of essential elements, making the PWA usable even in offline mode.
