Installation

Install unblessed based on your platform.

Node.js​

For server-side terminal applications:

pnpm add @unblessed/node
# or
npm install @unblessed/node
# or
yarn add @unblessed/node

TypeScript types are included - no need for separate @types packages.

Browser​

For browser-based terminal applications with XTerm.js:

pnpm add @unblessed/browser xterm @xterm/addon-fit
# or
npm install @unblessed/browser xterm @xterm/addon-fit

You'll also need to include the XTerm.js CSS:

import "xterm/css/xterm.css";

blessed Compatibility Layer​

For existing blessed applications (100% backward compatible):

pnpm add @unblessed/blessed
# or
npm install @unblessed/blessed

Simply replace your blessed imports:

- import blessed from 'blessed';
+ import blessed from '@unblessed/blessed';

Requirements​

  • Node.js: >= 22.0.0
  • Package Manager: pnpm, npm, or yarn
  • TypeScript (optional): >= 5.0.0

Verify Installation​

Create a simple test file:

// test.ts
import { Screen, Box } from "@unblessed/node";

const screen = new Screen();
const box = new Box({
  parent: screen,
  content: "It works!",
  width: "50%",
  height: "50%",
  top: "center",
  left: "center",
  border: { type: "line" },
});

screen.render();
setTimeout(() => process.exit(0), 2000);

Run it:

tsx test.ts
# or
ts-node test.ts
# or compile and run
