import { cx } from 'ramda-extension';

cx({ box: true, 'box--outline': false }, 'width-100'); // ".box .width-100"

Why to choose ramda-extension over other libraries?

We focus on functional point-free code. Our goal is to keep codebase composed only from ramda functions, not from own code. Basically, we are using only const and ES6 modules from the JavaScript itself.

We have a few functions with side-effects (like log and trace) to support better developer's experience in debugging process. It is only for development purpose and it should not be used in production code.


$ yarn add ramda ramda-extension


$ npm install ramda ramda-extension


We support CommonJS and ES modules syntax.

Import function as a named export (not recommended without treeshaking):

import { toKebabCase } from 'ramda-extension';
import { flatten } from 'ramda'; // standard ramda function (if needed)

toKebabCase('I wanna eat my kebab.') // "i-wanna-eat-my-kebab"
flatten([1, 2, [3, 4], 5]) // [1, 2, 3, 4, 5]
  • NOTE: standard ramda functions are still accessed via 'ramda'

Alternatively you can import it separately if your environment doesn't support treeshaking (Sse babel-plugin-transform-imports):

import toKebabCase from 'ramda-extension/lib/toKebabCase';

toKebabCase('I wanna eat my kebab.') // "i-wanna-eat-my-kebab"

If you prefer jQuery-style:

import * as R_ from 'ramda-extension'

R_.toKebabCase('I wanna eat my kebab.') // "i-wanna-eat-my-kebab"

NOTE: Ramda itself is not part of bundle, you need to add it manually


You can use Ramda-extension directly in the browser:

<script src="[email protected]/dist/ramda.min.js"></script>
<script src="[email protected]/dist/ramda-extension.min.js"></script>
