Offline-first mutation queue keeps Expo apps working when the network drops
Mobile networks lie. A request that works on office wifi stalls in a tunnel, times out in an elevator, and half-completes on a congested cell tower. If your Expo app fires mutations directly at the API and hopes for the best, every one of those moments becomes lost user data or a duplicated order. The fix is an offline-first mutation queue: an outbox that persists every write locally, retries it in order, and survives app restarts.
This pattern borrows from email clients and message brokers. The UI never talks to the network directly. It appends an intent to a durable outbox, renders the optimistic result immediately, and a background processor drains the outbox when connectivity allows. The app feels instant on good networks and stays correct on bad ones.
