Node.js Textbook - From Basics to Project Practice

With the arrival of the AI era, the skills required of developers are becoming increasingly complex. You might have thought, "I just need to be good at frontend," but when you try to create your own service or integrate AI features, you eventually hit a massive wall called the backend. However, as you try to start backend development, are you overwhelmed by how much there is to learn—from database design and authentication (Auth) to storage management and complex infrastructure setup? Now, you can lay down that heavy burden. In this course, we use Supabase, which solves all these backend functions at once. We will guide you through the fastest shortcut to becoming a full-stack developer who can "instantly" complete a backend without complex server knowledge and bring ideas to life immediately.

You will learn about what a node is, the latest JavaScript grammar, the node API, npm, the module system, databases, testing, and more. You will create a project using five practical examples. You will also deploy a service to the cloud and convert a node project to TypeScript.

In this lecture, we will practice developing programming thinking skills using JavaScript. Let's start with the web game, the multiplication table, and then create a word game, number baseball, a reaction speed test, tic-tac-toe, a lottery machine, rock-paper-scissors, a card matching game, a text RPG, a minesweeper, a 2048 game, and a mole catching game.

Let's learn NestJS, which is called the Spring of Node.js, and experience the convenience of Dependency Injection. Let's learn everything from API development, comparison with Express, deployment, and testing.

Let's use React and TypeScript together by adding TypeScript to a web game made with React and React Router, Redux, and MobX.

Learn Vue.js and Vuex and Vue Router, which are used with Vue, by creating 8 simple web games.

Learn React through web games. Get familiar with Classes and Hooks, and learn additional things like Context API, React Router, Webpack, and Babel.

Build and deploy community applications using the MERN Stack (MongoDB, Express, React, Node + Firebase)

🔥 Build a customized platform for Hanja learning! Leverage Google Gemini AI and Firestore to directly implement your own Hanja vocabulary book, stroke order animation, and even handwriting recognition!

This is a lecture on creating a map service from start to finish using the MERN stack (feat. TypeScript). Let's create each part step by step by looking at the official API documentation.

For job seekers who have created a portfolio as a backend developer but have nothing to show but an API, we will provide the experience of adding a frontend to create a web service.

This is a practical course where you can learn how to build a company website yourself using React, Node.js, and MongoDB. Let's build a full-stack project together with a basic background in React and Node.js!

Traditional React development and Next.js development are completely different approaches. This course penetrates the core of the latest Next.js 16 and teaches you the 'real' Next.js way of development. Experience how to achieve both performance and efficiency, from job portfolio projects to real-world projects. Let's develop the Next.js way! The course is structured to help you learn by doing, creating actual examples to understand how to apply Next.js features. You'll learn faster through actual code rather than theory, focusing on Server Components and covering Server Actions and caching strategies. Since the goal of the course is to catch up with the Next.js vibe as quickly as possible, the lectures are conducted using JavaScript. However, each lecture's examples are additionally provided as course materials created in TypeScript. December 18, 2025 - Updated to Next.js 16

From theory to practice. You can learn the entire web development process by deploying your self-developed website to the cloud.

This course is designed to help students understand React deeply and apply it confidently in real-world projects. Through years of teaching and mentoring, I’ve noticed that many learners struggle with React because they jump between tutorials without understanding the fundamentals or how everything connects in a real application. In this course, I solve that problem by teaching React step by step, starting from the basics and gradually moving toward advanced concepts. Every topic is explained clearly, then applied immediately in practical projects. I focus on best practices, clean code, and real development workflows, so students don’t just learn React — they learn how to think like React developers. By the end of the course, students will have built three complete, production-style applications and will feel confident creating and deploying their own React projects.
