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

Package Exports

  • string-width

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (string-width) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

string-width Build Status

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
