forkpty(3) bindings for node.js. This allows you to fork processes with pseudoterminal file descriptors. It returns a terminal object which allows reads and writes.

This is useful for:

• Writing a terminal emulator (eg. via xterm.js).
• Getting certain programs to think you're a terminal, such as when you need a program to send you control sequences.

node-pty supports Linux, macOS and Windows. Windows support is possible by utilizing the winpty library.

node-pty powers many different terminal emulators, including:

• Microsoft Visual Studio Code
• Hyper
• Upterm
• Script Runner for Atom.
• Theia

Do you use node-pty in your application as well? Please open a Pull Request to include it here. We would love to have it in our list.

var os = require('os');
var pty = require('node-pty');

var shell = os.platform() === 'win32' ? 'powershell.exe' : 'bash';

var ptyProcess = pty.spawn(shell, [], {
  name: 'xterm-color',
  cols: 80,
  rows: 30,
  cwd: process.env.HOME,
  env: process.env
});

ptyProcess.on('data', function(data) {
  console.log(data);
});

ptyProcess.write('ls\r');
ptyProcess.resize(100, 40);
ptyProcess.write('ls\r');

# Install dependencies and build C++
npm install
# Compile TypeScript -> JavaScript
npm run tsc

On Windows, you can show the winpty agent console window by adding the environment variable WINPTY_SHOW_CONSOLE=1 to the pty's environment. See https://github.com/rprichard/winpty#debugging-winpty for more information.

Powershell gives error 8009001d

Internal Windows PowerShell error. Loading managed Windows PowerShell failed with error 8009001d.

This happens when PowerShell is launched with no SystemRoot environment variable present.

This project is forked from chjj/pty.js with the primary goals being to provide better support for later Node.JS versions and Windows.
