Step 1 of 3
Lose signal
Picture a driver inside a warehouse with no signal. Tap Go offline and this app loses its connection to the server, for real.
What's happening behind the scenes
- • A service worker saved this app on your device, so it opens even with no connection.
- • Every tap is written to IndexedDB, a small database inside your browser.
- • Changes wait in an outbox and send in order when the signal returns. Each one has a unique ID, so a retry never creates a duplicate.
Outbox
Empty. Changes will show up here.

Up to dateFerrowind Cargo is a made-up company for this demo. The offline part is real: the app is cached by a service worker, your changes are stored in your browser, and they are sent to a real server when you go back online.
