Story integration

Use hook to get current direction:

You can also listen for the direction change event as follow:

import { Direction_MODE_EVENT_NAME } from 'storybook-rtl-addon';

// get channel to listen to event emitter
const channel = addons.getChannel();

// create a component that listens for the event change
function MyComponent({ children }) {
  // this example uses hook but you can also use class component as well
  const [direction, setDirection] = useState();

  useEffect(() => {
    // listen to direction change
    channel.on(Direction_MODE_EVENT_NAME, setDirection);
    return () => channel.off(Direction_MODE_EVENT_NAME, setDirection);
  }, [channel, setDirection]);

  return <div dir={direction}>{children}</div>;
}
