Description

Build a responsive Terminal User Interface (TUI) from scratch using OpenTUI Core and TypeScript 🚀 In this step-by-step tutorial, you’ll learn how to create a modern, flexbox-style terminal UI with panels, headers, and dynamic layout behavior—powered by Yoga layout under the hood. We’ll build reusable components like BoxRenderable, TextRenderable, and an ASCII banner header, then implement real resize event handling to make the layout adapt just like a browser app. ✅ Create structured TUI components ✅ Build side-by-side panels (50/50 split) ✅ Handle terminal resize events ✅ Stack panels vertically on smaller screens ✅ Add a persistent footer ✅ Run with Bun + live reload If you’ve ever wanted to bring responsive web layout concepts (flexbox) into the terminal, this video shows you exactly how.
