realm for React Native

Realm is a mobile-first database designed as a drop-in replacement for SQLite and AsyncStorage in React Native apps. It stores objects natively — no SQL, no ORM, no serialization overhead — making reads and writes dramatically faster than traditional key-value stores.

Realm supports live objects, meaning your UI automatically reflects database changes without manual re-fetching, and its Atlas Device Sync integration lets you sync data with MongoDB Atlas in real time with conflict resolution built in.

How realm will help you grow and be more successful?

1. Replace AsyncStorage with a real database in hours. Realm's React Native SDK gives you typed, queryable collections that persist across app restarts — upgrade from ad-hoc JSON storage to a proper data layer without rewriting your app architecture.
2. Build offline-first apps without extra infrastructure. Realm works entirely on-device with no network required, then syncs automatically to MongoDB Atlas when connectivity returns — giving your users a seamless experience regardless of connection quality.
3. Keep your UI in sync with zero boilerplate. Live objects and reactive queries mean your components re-render automatically when data changes, eliminating the polling loops and manual cache invalidation that slow down React Native development.
