A demo and reference implementation of the Application Shell architecture, using Service Workers to offline-cache an app's UI shell and populate content via JavaScript. It serves as an educational example of progressive web app instant-loading patterns, with graceful degradation to server-side rendering.
Use cases
- learn how to implement an application shell with service workers
- cache app shell for offline-first progressive web apps
- achieve sub-second first paint on repeat visits
- gracefully degrade to server-side rendering when service workers are unsupported
- reference architecture for instant-loading web apps
When to choose
- you want a working example of the app shell pattern for PWAs
- you need to understand service worker caching strategies for UI shells
- you are teaching or learning progressive web app performance techniques
When to avoid
- you need a maintained production framework - the project is unmaintained since 2018
- you need broad browser support including iOS service workers
- you want a turnkey PWA solution rather than a reference demo
