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.

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

Install

$ npm install --save string-width

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

stringWidth('古');
//=> 2

stringWidth('\u001b[1m古\u001b[22m');
//=> 2

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