# kebab-case [![NPM version][npm-image]][npm-url] > Convert a string to kebab-case, i.e. its dash separated form The difference between `kebab-case` and e.g. [`dashify`](https://www.npmjs.com/package/dashify) is that this module doesn't modify the string in any other way than transforming uppercased letters to their lowercased counterparts prefixed with `-`. Thanks to this there's also a [`reverse`](#kebabcasereversestr) function to do the opposite, i.e. get back the original value. This is used in [Unistyle](https://github.com/joakimbeng/unistyle) to transform JavaScript CSS properties to their CSS counterparts without losing a possible browser prefix, e.g: `WebkitTransform -> -webkit-transform`. ## Installation Install `kebab-case` using [npm](https://www.npmjs.com/): ```bash npm install --save kebab-case ``` ## Usage ### Module usage ```javascript var kebabCase = require("kebab-case"); kebabCase("WebkitTransform"); // "-webkit-transform" kebabCase.reverse("-webkit-transform"); // "WebkitTransform" ``` ## API ### `kebabCase(str)` | Name | Type | Description | | ---- | -------- | --------------------- | | str | `String` | The string to convert | Returns: `String`, the kebab cased string. ### `kebabCase.reverse(str)` | Name | Type | Description | | ---- | -------- | -------------------------- | | str | `String` | The string to convert back | Returns: `String`, the "unkebab cased" string. ## License MIT © [Joakim Carlstein](https://joakim.beng.se/) [npm-url]: https://npmjs.org/package/kebab-case [npm-image]: https://badge.fury.io/js/kebab-case.svg
