How do I update Realm in my React Native app?

To update Realm in your React Native app, you need to follow these steps: 1. Update the Realm package in your project. 2. Run the migration if your schema has changed. 3. Test your app to ensure everything works correctly.

What command do I use to update the Realm package?

You can use npm or yarn to update the Realm package. For npm, run npm install realm@latest, and for yarn, run yarn add realm@latest.

Do I need to handle migrations manually?

Yes, if your schema has changed, you will need to handle migrations manually. You can define a migration function in your Realm configuration.

Can you give me an example of a migration function?

Sure! Here's a simple example:

const migration = (oldRealm, newRealm) => {
  const oldObjects = oldRealm.objects('YourObject');
  const newObjects = newRealm.objects('YourObject');

  for (let i = 0; i < oldObjects.length; i++) {
    newObjects[i].newProperty = oldObjects[i].oldProperty;
  }
};

This function copies data from an old property to a new one.
