Embark on an exciting journey to master the MERN Stack alongside WebRTC and SocketIO. This course guides you step-by-step to develop an application equipped with group call functionality, leveraging WebRTC with simple-peer for seamless development. You'll employ SocketIO as a signaling server to facilitate real-time communication. By the end of this course, you'll be empowered to create your own WebRTC applications.

Course Objectives

Your newfound knowledge will transcend simple applications, enabling you to develop anything from real-time communication games to video chat platforms. You will learn to establish connections between peers (users) and integrate efficient communication systems.

Technologies Used

This course integrates the MERN Stack—comprising MongoDB, Express, React, and Node—with WebRTC and SocketIO for real-time communication capabilities.

What You Will Build

Throughout the course, you will construct a project from the ground up. Key functionalities include:

  • Login / Registration: Manage authentication using JWT Tokens.
  • Friends / Friends Invitation System: Establish and manage connections.
  • Realtime Chat Functionality: Utilize SocketIO and MongoDB for real-time interactions.
  • Creating Video Group Call Rooms: Develop rooms for video conferencing.

Course Requirements

This course is designed for learners with:

  • Basic knowledge of React
  • Basic understanding of Node
  • Some experience with websockets (SocketIO) is beneficial, but not mandatory; it will aid in comprehending the chat and video chat functionalities.

About the Author: Udemy

Udemy thumbnail

Udemy is the largest open marketplace for online courses on the internet. Founded in 2010 by Eren Bali, Oktay Caglar, and Gagan Biyani and headquartered in San Francisco, the company went public on the Nasdaq in 2021 under the ticker UDMY. The platform hosts well over two hundred thousand courses across software development, IT and cloud, data science, design, business, marketing, and creative skills, taught by tens of thousands of independent instructors. Roughly seventy million learners use it worldwide, and the corporate arm — Udemy Business — supplies a curated subset of that catalog to enterprise customers.

Because Udemy is a marketplace rather than a single editorial publisher, the catalog is uneven by design. The strongest material lives in the long-form, project-based courses authored by working engineers — full-stack JavaScript, React, Node.js, Python data science, AWS, Docker and Kubernetes, mobile development with Flutter and React Native, and cloud certification preparation. The CourseFlix listing under this source is the slice of that catalog that has been mirrored here for offline-friendly viewing, organized by topic and updated as new releases land. Pricing on Udemy itself swings dramatically with the site's near-permanent sales, which is why the platform is best treated as a deep reference catalog: pick instructors with strong reviews and a track record of updating their material rather than buying on the headline price alone.
