Terminal.js is a rendering engine for vt100-like terminals. It is written from scratch and supports most commonly used escape sequences.

a simple demo using the colors module:

var colors = require('colors'),
	Terminal = require('./index');

var terminal = new Terminal({columns: 20, rows: 2});

terminal.write("Terminal.js in rainbows".rainbow);

console.log(terminal.toString('ansi'));

There's also a webterminal using terminal.js: node-webterm
