  secret: process.env.PUSHER_SECRET!,
  cluster: 'us2',
  useTLS: true,
});

await pusher.trigger('my-channel', 'my-event', { message: 'Hello!' });

import Pusher from 'pusher-js';
const client = new Pusher(process.env.NEXT_PUBLIC_PUSHER_KEY!, { cluster: 'us2' });
const channel = client.subscribe('my-channel');
channel.bind('my-event', (data: any) => console.log(data));
Ably
import * as Ably from 'ably';

const client = new Ably.Realtime(process.env.ABLY_API_KEY!);

// Subscribe to a channel
const channel = client.channels.get('my-channel');
await channel.subscribe('greeting', (message) => {
