react-native-mmkv-storage

A fast and reliable key-value storage library for React Native, wrapping Tencent's MMKV (used by WeChat). Version 12.0.1 is current, with updates driven by RN breaking changes. It uses JSI for synchronous C++ operations (no async gaps), supports multiple encrypted instances, and ships TypeScript types. Unlike async-storage or simple MMKV wrappers, it offers React hooks (useMMKVStorage, useIndex) and 0.0002s read/write. Released under MIT, maintained on GitHub.
