Udemy – Building Video Call App with Javascript, Supabase and WebRTC 2025-5

Building Video Call App with Javascript, Supabase and WebRTC course. This comprehensive, project-based course teaches you how to develop a real-time video call app similar to Zoom and WhatsApp using Javascript, Supabase and WebRTC. First, you will learn the basic concepts of WebRTC, including its uses, limitations and key features. Then, you will learn the steps of building the app, from capturing user media and establishing a peer-to-peer connection to managing signaling and media streaming. Next, you will implement core project features such as user authentication, real-time audio and video communication, host-controlled call, and audio and video disconnection and reconnection. You will start by building the backend and integrating authentication with Supabase to ensure secure user access. Then, you will create a signaling system for seamless communication between users using Socket.IO. Next, you’ll set up a peer-to-peer connection with WebRTC so that users can communicate with minimal latency without the need for a central server. You’ll also add the ability to control audio and video during the call and design an attractive user interface with HTML and CSS. Finally, you’ll test the application with performance and functionality testing to ensure it works properly. This project will not only strengthen your understanding of real-time communications, but also teach you valuable skills such as managing peer-to-peer connections, signaling, and authentication, which are useful in developing chat platforms, live streaming, and online education.
