Interface: CachedScan

Defined in: types/scans/Scan.ts:217

Cached version of Scan with local-only fields for IndexedDB persistence.

Remarks​

Extends the base Scan type with fields that are only relevant for local caching and hydration. These fields are not stored in Azure.

Cache Strategy:

  • Scans are cached in IndexedDB for fast initial page load
  • Background sync fetches fresh data from Azure
  • cachedAt tracks cache freshness for stale-while-revalidate pattern

Example​

const cachedScan: CachedScan = {
  ...scan,
  cachedAt: new Date(),
};
