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

    What you'll learn

    Implement real-time features using WebSockets (Socket IO) for live chat, friends, and more.

    Create a powerful authentication system with JWT, and protected routes.

    Optimize performance with infinite scrolling, pagination, and query caching using React Query.

    Implement likes, comments, friends, conversations, and other key social features.

    Manage global and per-page state cleanly with Redux and React Query

    Optimize user experience with optimistic updates, and loading states

    Requirements

    Basic knowledge of JavaScript and React

    Know how to build basic applications with React and TypeScript

    Basic experience with NextJS is helpful

    Some exposure to React Query & Redux is a plus

    Eagerness to learn and build a real-time app!

    Description

    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, notifications, and user presence 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 feedbackInfinite scrolling for dynamic feed loadingThis 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.
