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
import stringWidth from 'string-width';
stringWidth('a');
//=> 1
stringWidth('古');
//=> 2
stringWidth('\u001B[1m古\u001B[22m');
//=> 2
API
stringWidth(string, options?)
string
Type: string
The string to be counted.
options
Type: object
ambiguousIsNarrow
Type: boolean
Default: true
Count ambiguous width characters as having narrow width (count of 1) instead of wide width (count of 2).
Ambiguous characters behave like wide or narrow characters depending on the context (language tag, script identification, associated font, source of data, or explicit markup; all can provide the context). If the context cannot be established reliably, they should be treated as narrow characters by default.
countAnsiEscapeCodes
Type: boolean
Default: false
Whether ANSI escape codes should be counted.
