Headless rendering

[seawerst]

In the roadmap discussion #5291, it's mentioned that "The core should be as headless as possible".

I was looking for a way to rerender/reparse the json and the HTML based on an updated collection of components. So a PATCH version of one of our components could refresh saved pages from our CMS via an update background process. I try using nodejs but there are multiple dependencies on browser's features.

Is this somewhere in the roadmap or maybe already possible somehow?
We manage to make something work by automating a chromium webbrowser control inside a .Net console app which is really not ideal.

Can you please indicate the related dependencies?
