Persisting Zustand State with AsyncStorage
Wrap a Zustand store with the persist middleware backed by AsyncStorage so state survives app restarts, and handle rehydration timing.
Why Persist State?
By default, Zustand state lives only in memory and is lost when the app closes. Persisting state means saving it to the device's local storage so it survives app restarts. This is essential for user preferences, authentication tokens, shopping carts, or any data the user expects to still be there when they reopen the app.
Installing AsyncStorage
AsyncStorage is the standard key-value storage API for React Native. In Expo managed workflow, install the community package @react-native-async-storage/async-storage. Zustand's built-in persist middleware works with any storage adapter, and AsyncStorage is the most common choice for mobile apps.
