I created the two plugins to test my knowledge of javascript. It is for this reason that the examples are related to FreeCodeCamp.
I created them a while ago. To say, the documentation for SDKDOMInstanceBase was not yet available. As soon as I have some time I plan to update them.
Given amazing tools like React and Preact, I would prefer to generate my non-canvas related UI code with these tools, have some messaging feature between the DOM and canvas / plugins, and run the (strictly speaking) game with Construct.
I think that to do this you need a completely different plugin.
