capacitor-offline-first

To build an offline-first Capacitor app, you use local storage like SQLite or IndexedDB for persistent data, network detection to monitor connectivity, and a sync manager to synchronize data automatically when the network is restored.

Conflict resolution during background sync is handled by implementing a structured strategy within the sync manager. This ensures data consistency across unreliable connections when synchronizing the local SQLite or IndexedDB repository with the server.

Yes, you can use service worker caching to store assets and apply optimistic UI updates to keep the app responsive. This allows the interface to reflect user actions immediately while data syncs in the background.

You test offline data synchronization by wiring up the offline repository and sync manager, then simulating network outages to verify network-aware services and automatic data synchronization function correctly across unreliable connections.

Yes, you need SQLite or IndexedDB for local storage in an offline-first app. These local databases provide the persistent storage required to retain data locally and support a sync-oriented workflow when the network is unavailable.
