How do I manage relationships in Realm with TypeScript?

To manage relationships in Realm with TypeScript, you can define your models with references to other models. For example, if you have a User model and a Post model, you can create a relationship by adding a property in the Post model that references the User model.

Can you show me a code example of that?

Sure! Here's a simple example:

class User extends Realm.Object {
  name!: string;
  posts!: Realm.List<Post>;
}

class Post extends Realm.Object {
  title!: string;
  user!: User;
}

In this example, each Post has a reference to a User, and a User can have multiple Posts.

What if I want to query posts by a specific user?

You can query posts by a specific user using Realm's query syntax. For example:

const userPosts = realm.objects(Post).filtered('user == $0', specificUser);

This will return all posts associated with the specified user.

Is there a way to handle cascading deletes?

Yes, you can handle cascading deletes by overriding the delete method in your model. You can manually delete related objects when a parent object is deleted.
