@wordpress/kebab-case

Convert strings to kebab-case, matching WordPress Core’s _wp_to_kebab_case().

This package exists because no off-the-shelf library matches the semantics of WordPress Core’s _wp_to_kebab_case() function, which WordPress needs to preserve for backwards compatibility.

Installation

Install the module

npm install @wordpress/kebab-case --save

Usage

kebabCase

Converts any string to kebab-case.

The conversion is designed to match WordPress Core’s _wp_to_kebab_case() function (and, transitively, Lodash’s _.kebabCase()): the package’s test suite covers every test case of the Core function. These semantics differ from other kebab-case implementations in how numbers are handled ('white23' becomes 'white-23', 'font2xl' becomes 'font-2-xl', yet 'white4th' stays 'white-4th').

import { kebabCase } from '@wordpress/kebab-case';

kebabCase( 'whiteToWhite' ); // 'white-to-white'
kebabCase( 'white2white' ); // 'white-2-white'
kebabCase( 'font2xl' ); // 'font-2-xl'
kebabCase( '#ffffff' ); // 'ffffff'
kebabCase( "i've done" ); // 'ive-done'

API
