Question 1

What is TermUI?

Accepted Answer

TermUI is a TypeScript framework for building terminal user interfaces (TUIs). It gives you JSX, a component model, theming, animations, routing, and state management for the terminal instead of the browser.

Question 2

How is TermUI different from Ink?

Accepted Answer

TermUI uses its own JSX runtime with no React dependency. It ships a router, CSS-like theming (TSS), spring animations, Zustand-style global state, and a hot-reload dev server. Ink reuses React directly and provides minimal extras. TermUI is pure TypeScript with zero C extensions.

Question 3

Does TermUI require React?

Accepted Answer

No. TermUI uses @termuijs/jsx, its own JSX runtime. You get useState, useEffect, useContext, useAsync, and memo() with no React dependency and no browser abstractions.

Question 4

What Node.js version does TermUI require?

Accepted Answer

Node.js 18 or later. LTS recommended.

Question 5

How do I install TermUI?

Accepted Answer

Run npx create-termui-app my-app to scaffold a project, or add packages directly with npm install @termuijs/core @termuijs/widgets @termuijs/jsx.

Question 6

How do I test a TermUI app?

Accepted Answer

Install @termuijs/testing and render your components into an in-memory screen. Use getByText(), fireKey(), and lastFrame() to query and assert. Works with Vitest and Jest. No terminal required.

Question 7

What terminals does TermUI support?

Accepted Answer

Any terminal emulator with ANSI escape code support: iTerm2, Kitty, Alacritty, Windows Terminal, GNOME Terminal, tmux, and SSH sessions. Requires 256-color support.

Question 8

How many packages does TermUI have?

Accepted Answer

13 packages: core, widgets, ui, jsx, tss, router, motion, store, data, quick, testing, dev-server, and create-termui-app.

Question 9

Is TermUI open source?

Accepted Answer

Yes. TermUI is MIT licensed. Source code is at https://github.com/Karanjot786/TermUI.

Question 10

Can I use TermUI for a system monitoring dashboard?

Accepted Answer

Yes. @termuijs/data provides live CPU, memory, disk, network, and process data. Pair it with Gauge, ProgressBar, Sparkline, and Table widgets to build an htop-style dashboard.
