The best way to store data locally in React Native depends on your needs: use AsyncStorage for simple key-value pairs, expo-sqlite for relational records, expo-secure-store for encrypted credentials, and react-native-mmkv for fast synchronous reads.

To securely store authentication tokens in Expo, use the expo-secure-store library. It provides encrypted storage specifically designed for sensitive secrets, ensuring that user credentials and tokens are kept safe on the device.

Use expo-sqlite instead of AsyncStorage when you need to store structured relational data, such as offline todo lists or complex caches. AsyncStorage is better suited for simple key-value settings and lightweight data caching.

Yes, react-native-mmkkv works with Expo and provides ultra-fast synchronous reads. It is ideal for managing feature flags and UI state where high performance and immediate data access are required in your React Native application.

Handling local storage migrations and cleanup in React Native involves using specific patterns for each storage type to satisfy security, size, and performance constraints. The Skill provides usage examples and cleanup procedures for safely removing outdated data.

Yes, you can persist offline data and user preferences in React Native without a backend. Use AsyncStorage for lightweight settings and expo-sqlite for offline relational records, ensuring data remains available on the device.
