Question 1

How to set up redux-persist with React Native?

Accepted Answer

Install @react-native-async-storage/async-storage, then explicitly pass it as the storage engine in your persistConfig, as shown in the v6 upgrade example. Use PersistGate to delay UI rendering until state is rehydrated, similar to web setups.

Question 2

redux-persist vs manual localStorage for Redux state

Accepted Answer

Redux-persist integrates seamlessly with Redux middleware, offering features like selective persistence, transforms, and migration tools, while manual localStorage requires custom logic for serialization and rehydration, making it better for simple cases only.

Question 3

How to handle state migration in redux-persist?

Accepted Answer

Use the createMigrate function to define synchronous migrations that transform old state versions to new ones. This is essential for app updates where state schemas change, preventing data loss or corruption.

Question 4

Does redux-persist work with server-side rendering?

Accepted Answer

Redux-persist is designed for client-side persistence and can cause issues in SSR, such as state mismatch or flicker. You may need to disable persistence during SSR or use custom hydration logic to sync server and client state.

Question 5

How to encrypt state with redux-persist?

Accepted Answer

Use the community library redux-persist-transform-encrypt. Add it as a transform in your persistConfig to automatically encrypt state before storage and decrypt it on rehydration, ensuring sensitive data like tokens are secure.

Question 6

Why is my redux-persist state not rehydrating properly?

Accepted Answer

Common causes include incorrect storage configuration, mismatched state reconcilers, or transform errors. Check the browser console for warnings, ensure your persistConfig key matches, and verify that transforms handle data types correctly.
