How do I migrate from Async Storage to a different storage solution?

How do I migrate from Async Storage to a different storage solution?

To migrate from Async Storage, you can follow these steps: 1. Choose a new storage solution (like SQLite or Realm). 2. Install the necessary libraries. 3. Write a migration script to transfer data from Async Storage to the new solution.

What are the benefits of using SQLite over Async Storage?

SQLite offers better performance for complex queries, supports transactions, and can handle larger datasets more efficiently than Async Storage.

Can you provide a sample migration script?

Sure! Here's a basic example:

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

const migrateData = async () => {
  const db = SQLite.openDatabase({name: 'mydb.db'});
  const keys = await AsyncStorage.getAllKeys();
  const data = await AsyncStorage.multiGet(keys);

  data.forEach(([key, value]) => {
    db.transaction(tx => {
      tx.executeSql('INSERT INTO myTable (key, value) VALUES (?, ?)', [key, value]);
    });
  });
};

This script retrieves all keys from Async Storage and inserts them into an SQLite database.

Are there any common pitfalls I should be aware of during migration?

Yes, some common pitfalls include not handling data types correctly, forgetting to clean up Async Storage after migration, and not testing the migration process thoroughly.
