expo-storage

A persistent key-value storage library for Expo and React Native apps that removes the size limitations of react-native AsyncStorage by using expo-file-system. Version 55.0.5 requires Expo SDK 54+, React 19+, and expo-file-system 19+. The library provides a simple, Promise-based API with TypeScript support, automatic JSON serialization for non-string values, and built-in security features like key validation and path traversal prevention. It stores data in the app's private document directory, ensuring persistence across restarts without size constraints.
