TypeScript in Bite-Sized Pieces

The third installment in the One Bite series! This is the kindest and most detailed Next.js course in the world. We’ll explore not only the App Router but also the Pages Router through hands-on projects.

Now it’s time to take on a real-world project 🔥 Together, we’ll build a production-grade social networking service with React.js + TypeScript + Supabase, implementing features such as authentication & authorization, infinite scrolling, image uploads, likes, infinitely nested comments, and dark mode. Along the way, we’ll also explore server and global state management techniques using Zustand and Tanstack Query.

In this course, you will learn about TypeScript.

Quickly learn TypeScript's syntax and usage with the easiest explanations.

This is the practical application section of "Introduction to TypeScript - From Basics to Practice". If you haven't taken the introductory course, please start with the introductory section first 😄

This is a TypeScript course designed to help you become a top-tier web developer through in-depth lessons. By completing this course, you will gain a profound understanding of the essence of TypeScript, enabling you to master React, Next.js, NestJS, and more.

We will develop a mobile portrait-oriented idle RPG game from start to finish using Claude Code, Vite, TypeScript, and HTML5 Canvas. This is a practical web game development project that implements core game systems such as auto-battle, gacha systems, and equipment enhancement step-by-step, with the goal of being ready for a future Google Play Store release.

If you’ve learned React, it’s time to apply TypeScript to a real-world project. Build a TodoList app from scratch, applying types to components and state, and gain practical React + TypeScript development skills by implementing CRUD functionality, storing data in LocalStorage, and deploying the app.

This course is a practical, hands-on guide for those who want to learn how to maximize development productivity in the AI era. Beyond simply learning how to use AI, we focus on how to utilize Claude Code in a real-world development environment and how to produce "proper results." Many developers use AI but still face issues such as: ❌ Inconsistent results ❌ Poor code quality ❌ Increasing project complexity To solve these problems, this course teaches you how to utilize AI as a "development partner" rather than just a tool through: ✔ Spec-based workflows ✔ Structured command systems ✔ Sub-agent and automation strategies Furthermore, you will gain the experience of completing and deploying a full application from start to finish by integrating with real-world services such as Firebase, Figma, GitHub, and Vercel.

In this course, you will be able to create a Reddit website from scratch, step by step.

I recommend this to those who want to learn how to easily create and distribute Android apps, Windows apps, and iOS apps. We will teach you the basics of TypeScript rather than JavaScript and Angular!

A course to learn the latest Node.js backend REST API using fastify, a Node.js framework boasting high speed, ORM Prisma, and Typescript.

Let's apply TypeScript to Node.js, add typings to existing npm packages, or create your own TypeScript library.

JavaScript, TypeScript Next is backend development! You will be able to develop REST API backends using NestJS, develop and deploy Socket IO.

"Why did the AI write this code?" or "Why can't it remember what I just said?" The frustration you encounter when using AI tools like Claude Code stems from not knowing how the tool actually works. This course flings open that black box. Over 25 lessons, we will build our own Coding Agent from scratch that functions exactly like real-world professional tools—giving the LLM 'eyes' to see files (Read), 'hands' to fix code (Edit), and 'feet' to execute commands (Bash). This isn't just about learning how to use a library. You will gain hands-on experience by implementing code to understand how AI perceives project structures, why it loses its memory during long conversations, and how to solve those issues technically (Sliding Window, Summary). Through this process, you will evolve from being a mere 'user' of AI tools to an 'AI provider' who understands the underlying principles and can customize and evaluate tools to fit your specific needs.

We will develop an avatar-based community app using React Native. You will learn the process of creating a high-quality community app that includes not only post creation but also comments/replies, likes, polls, and avatar generation.

This is a course where you will build a map service from scratch using the MERN stack (feat. TypeScript). Let's build it step-by-step while following the official API documentation.

If you don’t know why things keep breaking when you have AI do it, the problem isn’t coding—it’s telling it what to do without understanding “what’s happening.” I’ll teach you vibe coding by taking a web service with login and payments from scratch all the way to launching it on your own domain and getting it indexed by search engines, while understanding the context behind “What just happened?” at every step.

We have entered an era where it has become incredibly easy for web developers (especially React developers) to launch apps. With Expo, you can release both Android and iOS apps even faster. Let's become developers who can quickly launch apps through Expo.
