This project aims to do a server side rendering of a react application.
The difference to ReactDOMServer is the usage of jsdom to do a full render including data-fetching and other asynchronous operations without special apis.
The crucial part of the rendering is to decide when we are ready to send the html to the client.
This is done by rendering a node.js vm environment with a few wrapped global variables like Promises.
We do track all asynchronous work and when nothing is left to do, we return the current rendered state.
