Creatingg Serverless Functions

exports.handler = async (event) => {
 const payload = JSON.parse(event.body);
 const { collection, action, data } = payload;

 if (action === 'update' && collection === 'orders') {
 const notification = {
 userId: data.customer_id,
 title: 'Order Updated',
 body: `Your order #${data.id} is now ${data.status}`
 };
 // Send to messaging service (e.g., Firebase, WebSocket)
 await sendFCMNotification(notification);
 }

 return { statusCode: 200 };
};

Conclusion

Implementing real-time notifications with serverless services offers a compelling combination of scalability, cost control, and developer productivity. By leveraging event sources like Directus webhooks, serverless functions to process and format notifications, and robust messaging platforms such as WebSocket APIs or Firebase Cloud Messaging, you can deliver instant updates to users with minimal infrastructure overhead. The key to success lies in careful component design—ensuring idempotency, handling failures gracefully, and monitoring performance. As serverless technology matures, solutions like AWS Lambda SnapStart and Cloudflare Workers are reducing cold start times, making serverless even more viable for latency-Sistim sensitificetic syemos.
