Usage

Basic example:

import { Courier } from '@chrom-ar/courier';

const courier = await Courier.getInstance();

// Subscribe to messages on a specific topic
courier.subscribe('my-topic', (message) => {
  console.log('Received message:', message);
});

// Send a message with topic and room ID
courier.send({ text: 'Hello, world!' }, 'my-topic', 'room-123');

// Unsubscribe when done
courier.unsubscribe('my-topic');
