blessed (GitHub: chjj/blessed, License: MIT) is a terminal control library for Unix-like systems, enabling the construction of text user interface (TUI) applications. In other words it’s a curses-like library for node.js

npm install blessed


This will render a box with line borders containing the text ‘Hello world!’, perfectly centered horizontally and vertically.

var blessed = require('blessed');

// Create a screen object.
var screen = blessed.screen();

// Create a box perfectly centered horizontally and vertically.
var box ={
  top: 'center',
  left: 'center',
  width: '50%',
  height: '50%',
  content: 'Hello {bold}world{/bold}!',
  tags: true,
  border: {
    type: 'line'
  style: {
    fg: 'white',
    bg: 'magenta',
    border: {
      fg: '#ffffff'
    hover: {
      bg: 'green'

// Append our box to the screen.

// If our box is clicked, change the content.
box.on('click', function(data) {
  box.setContent('{center}Some different {red-fg}content{/red-fg}.{/center}');

// If box is focused, handle `enter`/`return` and give us some more content.
box.key('enter', function(ch, key) {
  box.setContent('{right}Even different {black-fg}content{/black-fg}.{/right}n');
  box.setLine(1, 'bar');
  box.insertLine(1, 'foo');

// Quit on Escape, q, or Control-C.
screen.key(['escape', 'q', 'C-c'], function(ch, key) {
  return process.exit(0);

// Focus our element.

// Render the screen.
