Example: How to subscribe to my user orders
This example can be used with all types of streams to receive your user data.

import socketClusterClient from 'socketcluster-client';

const WS_URL = 'ws-pro.kuna.io';
const WS_PORT = 443;

const client = socketClusterClient.create({
    hostname: WS_URL,
    port: WS_PORT,
    secure: true,
});

void (async () => {
  	// authorization by apiKey
  	const apiKey = ""; // your apiKey 
  	await Promise.all([
    	client.invoke('login', apiKey),
    	client.listener('authenticate').once(),
    ]);

  	// subscribe to 'order' channel (stream)
    const orderChanel = client.subscribe('order');
  
    // consume user order events
    for await (const data of orderChanel) {
        console.log('Order:', data);
    }
    
  	// attach listener to channel events
    await orderChanel.listener('subscribe').once();
})();
