Today we doesn't support react checksum or any other react methods for marking dom node, because it is the private part of react and may vary from version to version.
That's why, when you initialize your dom tree on the client, react re-render it. But in case of not very big tree, this render completely transparent to the user.

All you need to use it, is only install package and replace ReactDOMServer.renderToString to ReactRender.elementToString.
