Build an amazing full-stack web application...

Twitch logoNike logoNetflix logo

Next.js is the most popular React framework right now. It's used by big companies like Twitch, Nike, and Netflix, because it optimizes React apps for speed and SEO (search engine optimization). It comes with amazing features like server-side rendering, an integrated routing system, and automatic image optimization.

Express.js is one of the most popular backend frameworks, with a huge ecosystem of popular packages that stood the test of time. Combine this with the power of TypeScript, and you get amazing full-stack web apps that are both fast and robust.

You will build your own blog website a la But this is just an example project. You can build any website you want with the knowledge you'll get from this course.

...and learn how to implement these impressive features

  • User accounts & profiles. Sign up either via email & password or social providers (Google/GitHub)
  • Users can create and update blog posts via a markdown editor
  • Upload images & resize them on your own backend server
  • A fully-fledged comment system with sub-comments and edit/delete functionality
  • Pagination with both page numbers and infinite loading
  • A fully mobile-responsive layout & custom theme based on Bootstrap
  • A complete backend server built with Express.js and MongoDB

Why? Because web developers are in high demand.

Add this project to your portfolio to impress employers and clients, charge higher rates, or build your very own startup.

In the process, you will learn these important concepts

  • Server-side rendering and caching in Next.js, including advanced techniques like on-demand revalidation
  • Client-side request caching & revalidation using SWR (Next.js' React-Query alternative)
  • Advanced React concepts like context providers, custom hooks, and effect cleanup
  • Form handling with React-Hook-Form and Yup
  • Security best practices like validation of user input & file uploads, and rate-limiting
  • User email verification and password reset without expensive backend services like Firebase
  • Redis as a local session storage for super fast access
  • (Bonus) Deploy everything to a real web hosting and learn how to protect your server from hackers
  • and much more...

Frequently Asked Questions

    Q: Is this a beginner course?

    A: No. You will need some (beginner) knowledge in React or a similar declarative UI framework like Android's Jetpack Compose or SwiftUI. I will also not explain the fundamentals of JavaScript. You don't need any preknowledge of Next.js or TypeScript.
    If you have never worked with React before, my free MERN course on Youtube is the perfect prerequisite.

    Q: How is this course better than your free tutorials on Youtube?

    A: This course is more detailed and comprehensive than my Youtube tutorials. We really go in-depth to build a complete full-stack application with all important features.

    Q: Other courses are much cheaper. Why should I buy this course instead?

    A: The majority of courses and tutorials out there are poorly prepared and important points are often swept under the rug, especially when they are not obvious. This course is more expensive because it is thoroughly researched, comprehensive, and structured in a logical & understandable way.

    Q: Why doesn't this project use Next.js' API routes instead of an Express backend?

    A: Next.js API routes are serverless functions, which means they can't do everything a real server, like Express, can do. Also, the ecosystem of available tools & middlewares is much greater for Express, because it has been around for so long. Thirdly, many developers prefer to have frontend and backend code separated. That being said, we will also implement one API route in this course, so you will learn how this works as well.

    Q: Does this course use Next 13's new app directory?

    A: Yes and yes! You will build the project in the pages directory first, and then migrate it to the new app router. This way, you learn both approaches and are equipped to work on any Next.js project you encounter in the future. Lots of legacy codebases will still use the pages directory for a long time, so it's important to know both.

    Q: Does this course teach Next.js 14?

    A: Next.js 14 didn't bring any new APIs or significant changes, except for performance improvements that are hidden from you. This course is fresh and just as relevant for Next.js 14.

    Q: Does this project use a state management library like Redux?

    A: Nope. Complicated state management libraries are overkill unless you're working on a really big project. They also make it harder to learn other concepts because they overcomplicate the code. Instead, you will use SWR which caches data from the backend and makes it available across the app. You will also use React Context to avoid prop-drilling.

    Q: Isn't stack XYZ better to build a blog?

    A: The blog we're building in this course is just an example project. It's a great way of learning full-stack development. The point of this course is not that everyone builds a blog. You can create (and work on) completely different kinds of projects with the knowledge you learn here.

    Q: Do I get lifetime access to the videos?

    A: Yes, you can watch these videos whenever you want, forever.

    Q: Do I get updates to this course for free?

    A: Yes. If you buy this course, you'll get any future updates for free.
