How it works
Dexie wraps the browser's IndexedDB in a promise-based API: declare tables and indexes once, then query with calls such as where('age').above(18). Its liveQuery and React hooks re-run a query whenever the data underneath changes, which suits offline-first apps.
The library is open source. Dexie Cloud is an optional service from the same team that adds sync between devices, sign-in and sharing.
