var transform = require('coffee-react-transform');

module.exports = {
  process: function(src, path) {
    if (coffee.helpers.isCoffee(path)) {
      compiled_cjx = transform(src);

    }

    return src;
  }
};

So use CJSX syntax to write React components.

    {if this.state.isChecked then this.props.labelOn else this.props.labelOff}
