markdown to Html ReactJs

есть готовый компонент для этого:

var React = require('react');
var ReactDOM = require('react-dom');
var ReactMarkdown = require('react-markdown');
var input = '# This is a header\n\nAnd this is a paragraph';
ReactDOM.render(
    <ReactMarkdown source={input} />,
    document.getElementById('container')
);
