Isomorphic Ansi-Escapes

ANSI escape codes for manipulating the terminal

A fork of sindresorhus/ansi-escapes that remove node dependencies to support in-browser use (exactly, xterm.js).

Installation

# Using pnpm
pnpm add isomorphic-ansi-escapes
# Or yarn
yarn add isomorphic-ansi-escapes

Use with xterm

import ansiEscapes from 'isomorphic-ansi-escapes'
import { Terminal } from 'xterm'
import 'xterm/css/xterm.css'

...
const term = new Terminal({...})
...

// Moves the cursor two rows up and to the left
term.write(ansiEscapes.cursorUp(2) + ansiEscapes.cursorLeft)
//=> '\u001B[2A\u001B[1000D'
