const ws = new WebSocket('wss://example.com/orderbook');
ws.on('open', () => {
console.log('WebSocket connection established');
ws.send(JSON.stringify({ action: 'subscribe', channel: 'orderbook' }));
});
ws.on('message', (data) => {
const orderBook = JSON.parse(data);
console.log('Updated Order Book:', orderBook);
});
ws.on('error', (error) => {
console.error('WebSocket error:', error);
});
