TUI Development with TypeScript

What You Will Build

Module 1 — Foundations

Learn how terminals actually work, what ANSI escape codes are, and write your first TUI programs from scratch.

Module 2 — Input & Control

Master raw mode keyboard input, build a render loop, implement double buffering, and handle terminal resize.

Module 3 — UI Components

Build reusable boxes, menus, text inputs, and layouts — then combine them into a real task manager app.

Module 4 — Terminal Games

Implement a game loop, sprite rendering on a grid, collision detection, and build a fully playable Snake game.

Why This Course

TUIs are back. Tools like lazygit, k9s, btop, and countless others prove that a great terminal UI can be faster and more expressive than a web app for the right use case.

This course teaches you how terminals work, not just how to use a library. You will understand why things like raw mode, ANSI codes, and render loops exist — so when you do reach for a library, you know what it is doing for you.
