AsyncStorage

AsyncStorage is a simple, unencrypted, asynchronous, persistent, key-value storage system for React Native applications. It allows developers to store data locally on a user's device, persisting across app restarts and device reboots. It is commonly used for caching data, storing user preferences, or saving application state.

Also known as: Async Storage, asyncstorage, async-storage, React Native AsyncStorage, RN AsyncStorage

Why learn AsyncStorage?

Developers should use AsyncStorage when building React Native apps that need to persist small amounts of data locally, such as user authentication tokens, app settings, or cached API responses. It is ideal for scenarios where data does not require encryption or complex querying, and when a lightweight, built-in solution is preferred over more heavy-duty databases like SQLite.
