rc-classnames

Manage classNames conditionally in React and JSX easily in any format

Install with npm:

npm install rc-classnames --save

Or with bower:

bower install rc-classnames

You can use CDN as well:

<script src="https://npmcdn.com/rc-classnames/index.js"></script>

You can use with UMD as well.

We use SemVer for versioning.

Why react-classnames

Do you remember when you wanted a button in JSX to have diffrent states conditionally? You might end up with something like this:

<button className={'button' + (isDisabled ? ' button--disabled' : '') + (hasRadius ? '' : 'button--no-radius'} />

Or in ES6 syntax:

<button className={`button${isDisabled && ' button--disabled'}${hasRadius || button--no-radius}`} />

Oh, It's very hard to read. But with rc-classnames those days are gone! It's intelligent! You can give it classNames in Any Format you want and it will generate a neat classname for you. Let's see how can we implement our button with rc-classnames:

// ES6
import c from 'rc-classnames';

// CommonJS
var c = require('rc-classnames');

<button className={c('button', {
  'button--disabled': isDisabled,
  'button--no-radius': !hasRadius
})} />

Even with Arrays and Nested Arrays:

<button className={c(
  ['button', 'header__button', ['button--large']],
  {
    'button--disabled': isDisabled,
    'button--no-radius': !hasRadius
  }
)} />

Or Arrays containing objects:

<button className={c(
  'button',
  [
    'header__button',
    {
      'button--disabled': isDisabled,
      'button--no-radius': !hasRadius
    }
  ]
)} />

See? Give your classNames in Any Format you wish!

Usage Without react

While main purpose of this library is using with React, you can use it without react, just call the exported function.

First import index.js file with script tag:

<script src="rc-classnames/index.js"></script>

ReactClassNames is available globally with Pure JS:

window.getElementById('someId').className = ReactClassNames('hey', { 'foo': true, 'bar': false });

We support UMD as well.

TODO

• Add HoC for custom classNames prop in React
• ... If you want a feature or have an idea, fill an issue and tell me what you want.

Have problems?

I hope you don't have any problem with the library, but if library have problems, fill an issue containing the case with a seperate Repo and me or other friends will answer ASAP. Please double check your code before sumbiting issues.
