How can I manage data storage in React Native?

How can I manage data storage in React Native?

You can use AsyncStorage for simple key-value storage, or libraries like Realm and SQLite for more complex data.

What are the differences between AsyncStorage and SQLite?

AsyncStorage is great for lightweight data, while SQLite is better for structured data and complex queries.

Can you show me a code example using AsyncStorage?

Sure! Here's a simple example:

import AsyncStorage from '@react-native-async-storage/async-storage';

const storeData = async (value) => {
  try {
    await AsyncStorage.setItem('@storage_Key', value);
  } catch (e) {
    // saving error
  }
};

const getData = async () => {
  try {
    const value = await AsyncStorage.getItem('@storage_Key');
    if(value !== null) {
      // value previously stored
    }
  } catch(e) {
    // error reading value
  }
};

This stores and retrieves a value using AsyncStorage.

Are there any limitations to using AsyncStorage?

Yes, AsyncStorage is not suitable for large amounts of data or complex queries. For those, consider using SQLite or Realm.
