We will implement a more practical example with liveblocks and Yjs.

import { createClient } from '@liveblocks/client';
import { getYjsProviderForRoom } from '@liveblocks/yjs';

const client = createClient({
    publicApiKey: 'pk_dev...',
});
const { room, leave } = client.enterRoom('my-room-id', {});

const yProvider = getYjsProviderForRoom(room);
const yDoc = yProvider.getYDoc();

You can open this example in multiple browser windows.
