ProseMirror as the front-end for a REST API

Excuse the beginner-level of this topic;

What would it take to have a single page that queries a REST API with a token, populates the text area with markdown based on a JSON variable, then uses AJAX to submit any changes to the same API?

Of note:

  • This is my first React rodeo, but not my first web-app rodeo
  • As I get more comfortable with this basic functionality, more content will be populated and submitted using the same page.
