App Shell
Service Workers
App Manifest
The application shell is a simple design
concept using minimal HTML, CSS, and
JavaScript to power the app user
interface. When the app shell is cached
offline, it ensures instant, smooth user
experience to users on repeat visits.
Service Worker is a powerful JavaScript
file that runs in the background of the
browser. It enables offline functionality,
push notifications, updating content in
the background, content caching,
content fetching, and a whole lot more.
App Manifest is a simple JSON file that
allows a user to install an app from the
browser and pin it to their device's
homescreen. It delivers app-like look and
feel while increasing user engagement
through push notifications.
