string-width


Get the visual width of a string - the number of columns required to display it


Some Unicode characters are fullwidth and use double the normal width. ANSI escape codes are stripped and doesn't affect the width.

Useful to be able to measure the actual width of command-line output.


Install

$ npm install string-width


Usage

const stringWidth = require('string-width');

stringWidth('a');
//=> 1

stringWidth('古');
//=> 2

stringWidth('\u001B[1m古\u001B[22m');
//=> 2
