A more scalable way of architecting this project could be to use react-reconciler to build a JSON tree, which is then passed through to a walk function which renders to XD outside of the React cycle.

The JSON tree generation could even be parallelised in a separate process to speed up rendering, and would then allow for using yoga-layout, etc.

By adding a token that optionally can get passed to client, dev, and server (which checks the token in requests by client and dev), server could be deployed to a server in the WWW, meaning testers could be anywhere in the world (dreaming big 😜) and the application wouldn't be limited to the same local network.
