Question 1

How do I install react-native-shared-preferences in React Native 0.60+?

Accepted Answer

For React Native 0.60 and above, you must manually link the module since auto-linking isn't supported. Follow the README steps to edit settings.gradle, build.gradle, and MainApplication.java, but be aware of potential compatibility issues with newer versions.

Question 2

Can I use react-native-shared-preferences on iOS?

Accepted Answer

No, this module is specific to Android's SharedPreferences. For iOS storage in React Native, you'll need alternatives like AsyncStorage or platform-specific libraries such as react-native-mmkv.

Question 3

react-native-shared-preferences vs AsyncStorage: which is better?

Accepted Answer

Use react-native-shared-preferences for Android-only apps needing native performance and reliability. AsyncStorage is cross-platform but may have slower performance; this module is ideal if you're prioritizing Android optimization.

Question 4

How to store JSON objects with react-native-shared-preferences?

Accepted Answer

You need to serialize JSON objects to strings before storage, as the module only handles strings. Use JSON.stringify() when setting items and JSON.parse() when retrieving them to manage complex data.

Question 5

Is react-native-shared-preferences secure for sensitive data like tokens?

Accepted Answer

No, SharedPreferences is not encrypted by default, so it's not secure for sensitive information. For better security, consider using libraries like react-native-keychain or implementing encryption before storage.

Question 6

Does react-native-shared-preferences work with Expo?

Accepted Answer

No, it requires native module linking, which is incompatible with Expo's managed workflow. You'd need to eject from Expo or use a different storage solution like AsyncStorage within Expo.
