Async Storage is a persistent key-value storage system for React Native applications.
The tool solves the problem of storing data locally on a device in a way that persists across app sessions. It provides an asynchronous API compatible with the Web Storage API, allowing developers to read and write data without blocking the main thread. The implementation uses SQLite on Android, iOS, and macOS to handle persistence, IndexedDB on Web, and platform-specific fallbacks on visionOS and Windows. The tool supports batch operations and multi-database functionality, enabling more complex storage patterns than simple single-key access.
Async Storage suits any React Native project that needs local data persistence without encryption requirements. It works across mobile platforms and web, making it appropriate for cross-platform applications. The tool is unencrypted, so it should not be used for sensitive information like passwords or tokens. Developers should verify their React Native version meets the minimum requirements, which vary by platform: iOS and Android require version 0.76 or later, while macOS, visionOS, and Windows have higher minimums.
The project maintains active support across multiple platforms with regular updates to align with React Native releases. Development activity shows consistent engagement with platform-specific improvements and maintenance of compatibility across the supported ecosystem.
