    <title>React Demo</title>

<body>
    <div id="container" class='container'></div>

<script src='bundle.js'></script>
</html>

app.jsx

'use strict';
var React = require('react');
var ReactDOM = require('react-dom');

var Hello = React.createClass({
    render : function(){
        return (
            <p>Hello world!</p>
        );
    }

ReactDOM.render(
    <Hello />,
    document.getElementById('container'));
