Question 1

How to implement auto-sync with a backend in react-native-storage?

Accepted Answer

Define sync methods in the storage.sync object for each key, which are invoked when data is missing or expired. For example, create a user function that fetches from an API and saves the response locally using storage.save.

Question 2

react-native-storage vs AsyncStorage directly: which is better?

Accepted Answer

React-native-storage adds features like expiration, sync, and batch operations on top of AsyncStorage. Use it if you need these advanced capabilities; otherwise, AsyncStorage alone is lighter for basic storage.

Question 3

Does react-native-storage support data encryption?

Accepted Answer

No, it does not include built-in encryption. Data is stored as-is using the underlying backend, so you must implement encryption separately before saving if security is a concern.

Question 4

How to set up react-native-storage for both React Native and web?

Accepted Answer

Configure storageBackend as AsyncStorage for React Native or window.localStorage for web in the constructor. This ensures the same API works across platforms, but you need to handle environment-specific imports.

Question 5

Is react-native-storage still actively maintained?

Accepted Answer

The README suggests using TanStack Query as a modern alternative, and while it has contributors, activity may be limited. Check GitHub issues and recent commits for current maintenance status.

Question 6

How to handle batch data loading with multiple keys?

Accepted Answer

Use getBatchData with an array of load parameters to fetch data for different keys in one call. This improves efficiency by reducing promise chains and allows control over syncInBackground settings.
