UpUp is a tiny JavaScript library that uses service workers to let websites serve content to users even when they are offline. With a single command, developers define the content and assets users see when their connection drops.
Use cases
- make my website work offline
- show fallback content when users lose connection
- add offline-first support to a site with service workers
- build a progressive web app that caches content
- serve cached pages to users on planes or subways
When to choose
- you want a dead-simple, one-command way to add offline content to a site
- you need a lightweight service worker wrapper without a full PWA framework
- your site is served over HTTPS and targets Chrome, Firefox, or Opera
When to avoid
- you need fine-grained control over service worker caching strategies
- you require broad browser support including Safari or older browsers
- your site cannot be served over HTTPS
