Build a modern social media app with Next.js, React Query & Socket IO – real-time chat, posts, likes & more.

Want to build a real-time social media app with modern tools like NextJS, React Query, and Socket IO? This course is for you.

In this hands-on project-based course, you’ll build the frontend of a full-featured social media platform from scratch. You’ll implement real-time features such as live chat, reactions, and friends using WebSockets (Socket IO). With React Query, you’ll master efficient data fetching, caching, pagination, and optimistic updates to provide a smooth user experience.

We’ll use NextJS App Router, Material UI, and TypeScript to build clean, scalable, and modern UI components. You’ll also implement core social media features like posts, likes, comments, and friends systems with a fully interactive UI.

Whether you’re an intermediate developer looking to build your portfolio or a React developer aiming to learn advanced tools and patterns — this course will guide you step by step.

Another major focus is React Query—one of the most powerful and widely-used libraries for handling server state in modern React apps. You’ll learn how to effectively use it for fetching, caching, and mutating data, along with advanced techniques like:

• Optimistic updates for instant UI feedback

• Infinite scrolling for dynamic feed loading

This course isn’t just about building a project—it’s about understanding when, why, and how to use the right tools for building fast, scalable, and real-time frontend applications.

Note: This course does not focus heavily on Server Components, as we are building a social media app—a type of application where data changes frequently and requires real-time updates. Instead, we prioritize the tools and techniques best suited for highly dynamic, interactive user experiences.
