The benefits of an app shell architecture with a service worker include:
- Reliable performance that is consistently fast. Repeat visits are extremely quick. Static assets and the UI (e.g. HTML, JavaScript, images and CSS) are cached on the first visit so that they load instantly on repeat visits. Content may be cached on the first visit, but is typically loaded when it is needed.
- Native-like interactions. By adopting the app shell model, you can create experiences with instant, native-application-like navigation and interactions, complete with offline support.
- Economical use of data. Design for minimal data usage and be judicious in what you cache because listing files that are non-essential (large images that are not shown on every page, for instance) result in browsers downloading more data than is strictly necessary. Even though data is relatively cheap in western countries, this is not the case in emerging markets where connectivity is expensive and data is costly.
