  // The extensive options are required because the default for cli-table is to have
  // borders between every row and column.
  const innerTableOptions = {

View more ways to use window-size

window-size

Reliable way to get the height and width of terminal/console, since it's not calculated or updated the same way on all platforms, environments and node.js versions.

Install

Install with npm:

$ npm install --save window-size

Usage

var size = require('window-size');

CLI

$ window-size
# height: 40
# width : 145

API

windowSize

The main export is either an object with width and height properties, or undefined if unable to get width and height.

var size = require('window-size');
console.log(size); 
//=> {width: 80, height: 25}

.get

Calls the main function to get the up-to-date window size.

console.log(size.get());
//=> {width: 80, height: 25}

Example

See example.js for the code used in the below gif.

process.stdout.on('resize', function() {
  console.log(size.get());
});

HEADS UP!

Note that some platforms only provide the initial terminal size, not the actual size after it has been resized by the user.

.env

Get process.env.COLUMNS and process.env.ROWS, if defined. Called by the main function if for some reason size was not available from process.stdout and process.stderr.

console.log(size.env());

.tty

Attempts to get the size from tty. Called by the main function if for some reason size was not available from process.stdout, process.stderr or process.env.

console.log(size.tty());

.win

Get the terminal size in Windows 10+.

console.log(size.win());

Note that this method calls execSync to get the size, and must be called directly, as it is not called by the main function.

.tput

Get the terminal size by calling the unix $ tput command.

console.log(size.tput());

Note that this method calls execSync to get the size, and must be called directly, as it is not called by the main function.

utils

In some environments the main export may not be able to find a window size using the default methods. In this case, size will be undefined and the functions will not be exported.

Because of this, the functions have been exported in a separate file and can be required directly.

var utils = require('window-size/utils');
console.log(utils.win());
