react-native-onyx

Persistent state management library for React Native, wrapping pub/sub patterns around AsyncStorage-like backends. Current version 3.0.71, active development, with frequent releases. Key differentiators: automatic persistent storage, collection-oriented key design (e.g., report_1234), React hooks (useOnyx) and non-React subscribers (Onyx.connect). Requires idb-keyval, react-native-device-info, react-native-nitro-modules, and react-native-nitro-sqlite as peer dependencies. Ships TypeScript definitions, supports browser bundling via Webpack. Unlike Redux or MobX, Onyx is tailored for React Native's offline-first, persistent-storage needs with minimal boilerplate.
