Description
Currently, FreshScan AI requires a stable internet connection to perform scans and log data to Supabase. In many real-world market environments (where this tool is intended to be used), cellular connectivity can be unreliable.
I propose implementing a robust offline-first synchronization strategy to ensure that scanning remains functional even when the user is offline.
Proposed Implementation
Local Data Persistence: Integrate IndexedDB (via a library like Dexie.js) to cache scan results and Market Map data locally on the device when the network is unavailable.
Background Sync API: Utilize the Service Worker Background Sync API to queue failed POST requests (scans) and automatically replay them once the user regains connectivity.
Conflict Resolution: Implement a "Sync Status" indicator in the UI that provides feedback to the user on whether their scan is "Pending Sync," "Synced," or "Sync Failed."
Data Integrity: Given that this app deals with freshness indices, we must implement a deduplication layer to ensure that if a scan is queued multiple times, it only records a single entry once the connection returns.
