Udemy – NestJS: Build a Real-Time Social Media API (/w WebSockets) 2025-6

NestJS: Build a Real-Time Social Media API (/w WebSockets). This hands-on course shows you how to build a real-time social media API using NestJS and WebSockets (Socket.IO). This course goes beyond just learning syntax, but focuses on understanding the fundamental concepts of real-time communications. You’ll learn how sockets work, how to transfer data between a client and a server, and how to design scalable and responsive systems. Rather than providing ready-made code, this course focuses on developing your skills in reading documentation, critical thinking, and implementing independent projects. It first covers the basics of WebSockets, from the TCP handshake to upgrading HTTP to a persistent connection. It then builds a simple chat application with raw WebSockets to provide a solid foundation before moving on to libraries like Socket.IO. Once you’ve mastered the basics, you’ll explore Socket.IO concepts like custom events, rooms, and namespaces. Next, you’ll learn the basics of NestJS, including modules, controllers, services, and guards, and use them to build a real-time social media backend. This course is a project-based training that helps you think like a backend engineer. If you’re familiar with JavaScript/TypeScript, have experience with Node.js or NestJS, and want to advance your skills in real-time systems architecture, this course is designed for you.

What you will learn

Understand the basics of WebSockets: from TCP and HTTP handshakes to persistent connections.
Building a Real-Time Chat App: Using Raw WebSocket APIs to Gain Fundamental Knowledge.
Using Socket IO: To implement custom events, rooms, and namespaces for scalable communications.
Applying NestJS principles: (modules, services, controllers, gateways, guards) to a real API.
Integrate JWT authentication with WebSockets: for secure real-time communications.
Building real-time features: such as messaging, conversations, posts, and comments.
Designing a scalable real-time social media backend: from scratch.
Structuring WebSocket gateways and services: cleanly in a NestJS codebase.
Thinking from a front-end perspective: for effective shaping and presentation of real-time data.
