What does Node.js TTY module contains?

by

The Node.js TTY module contains tty.ReadStream and tty.WriteStream classes. In most cases, there is no need to use this module directly. You have to used require (‘tty’) to access this module.

Syntax:
var tty = require(‘tty’);

The Node.js tty module contains functionality related to terminal input and output. It provides an interface for working with terminal devices, such as obtaining information about the terminal and controlling its behavior. Some of the key components of the tty module include:

  1. tty.ReadStream: Represents a readable stream for accessing input from the terminal.
  2. tty.WriteStream: Represents a writable stream for sending output to the terminal.
  3. tty.isatty(fd): A function used to determine whether a given file descriptor refers to a terminal.
  4. tty.setRawMode(mode): A method to set the terminal to raw mode, which allows applications to read input character by character rather than line by line, and enables more advanced input handling.
  5. tty.clearScreenDown(stream): A method to clear the screen from the current cursor position down.

These are some of the key functionalities provided by the tty module, which are essential for building interactive command-line applications in Node.js.
