Service Workers & Progressive Web Apps

How should you handle Service Worker updates?

self.addEventListener('activate', event => {
  event.waitUntil(
    caches.keys().then(cacheNames => {
      return Promise.all(
        cacheNames.map(cacheName => {
          if (cacheName !== CACHE_VERSION) {
            return caches.delete(cacheName);
          }
        })
      );
    })
  );
});

Force update on every page load
Implement version control and clean old caches
Proper Service Worker update handling involves: 1) Implementing version control for cache names, 2) Cleaning up old caches during the 'activate' event, 3) Properly managing the cache update process to avoid serving stale content, and 4) Optionally notifying users about available updates. This ensures smooth updates without breaking the application's functionality.
