Veet Video Calling App
Project Overview
A serverless video calling application built using Cloudflare's Durable Objects and WebRTC technology. This project demonstrates the power of stateful serverless architecture while exploring modern JavaScript and real-time communication patterns. The implementation showcases how to maintain state in a serverless environment using Durable Objects for coordinating WebRTC connections.
