If you are a TypeScript/Node.js developer you can take a look at:

http://github.com/prettydiff/aphorio

It is a dashboard for docker, web servers, os data, and more. It exposes most of Node's APIs to a browser front-end in a very low level (low as in as low as you can get with Node). It's internal components should allow you to tinker with almost any non-graphical idea without excess dependencies.

My current effort is to make the application self-documenting and self-descriptive by starting with expose the TypeScript definitions for the app's internal services to the UI as documentation. I am thinking about the best way to go about this.
