React code vs. esperanto

I've tried to put this simple file under app/components/

"use strict";
var React = require('react');

var Main = React.createClass( {
    displayName: 'Main',
    render: function() {
        return (
        <div>
                <p>main content</p>
            </div>
        );
    }
} );

export default Main;

but the start fails with this error:

events.js:85
      throw er; // Unhandled 'error' event
            ^

In line 8 there is the <div> html tag.
