Offline-First Edge Cache & Sync
Local-first storage with deferred cloud sync — keep transacting through every network outage
Offline-first persistence layer that commits every transaction to a local SQLite or IndexedDB store first, then queues and replays it to the cloud API once connectivity returns. Tracks per-record reconciliation state, retries failed pushes with idempotency keys, and surfaces a clear sync indicator so frontline staff keep working — even when WiFi or 4G drops mid-session.
Features
What's Included
Local-First Writes
Every create, update, and delete is committed to a local SQLite or IndexedDB store first and confirmed to the user instantly — no waiting on a server round-trip before staff can continue.
Outbound Sync Queue
Pending changes sit in a tamper-resistant outbox table and replay to the API in order once connectivity returns, with exponential-backoff retries and per-record state.
Idempotent Server Confirmation
Each queued record carries a client-generated idempotency key so duplicate retries are safely ignored, and local rows only transition to confirmed after the server acknowledges.
Conflict Resolution Strategies
Configurable last-write-wins, server-wins, or custom merge rules per table reconcile records that drifted in two places during the offline window.
Reference Data Pre-Cache
Read-mostly tables — catalogue, pricing, customer master, lookup lists — are version-stamped and pre-downloaded so reads run locally without ever hitting the network.
Sync Status & Recovery UI
Pending, synced, and failed badges per record plus an admin view to inspect stuck items, force a manual replay, or purge corrupt entries.
