I've been working on a similar project - if you want a similar solution with a little less setup, navigate to your build/dist directory and:

  npm install -g prerendercloud-server
  prerendercloud-server .

If you want to run your own rendertron instance as opposed to service.prerender.cloud, you can use that same package with an environment variable:

  PRERENDER_SERVICE_URL=http://localhost:8080 prerendercloud-server .
