Built with React Side Effect.

Dependencies: React >= 0.13.0

What it looks like

import BodyClassName from 'react-body-classname';
 
const Basic = () => (
  <BodyClassName className="helloworld">
    <h1>You ate a whole wheel of cheese?</h1>
  </BodyClassName>
);
// -> document.body.className === "helloworld"
 
const Nested = () => (
  <BodyClassName className="outside">
    <div>
      <BodyClassName className="inside">
        <p>I‘m not even mad</p>
      </BodyClassName>
    </div>
  </BodyClassName>
);
// -> document.body.className === "outside inside"
 
const GoCrazy = () => (
  <BodyClassName className={Array(8).join(''/0) + ' batman!'}>
    <h1>I'm impressed</h1>
  </BodyClassName>
);
// -> document.body.className === "NaNNaNNaNNaNNaNNaNNaN batman!"

Note: Only supports a single child as props.

Server Usage

When using server-side, use BodyClassName.rewind() after rendering components to string to retrieve the combined class name. Then chuck that into your HTML template.

Important: This component keeps track of mounted instances, so if you don't call BodyClassName.rewind() you'll get a memory leak.
