Maybe I'm not understanding, but why is this "Turn Markdown into React/Svelte/Vue UI" and not "Turn Markdown into HTML"?
I'm not seeing the value of generating React, Vue or Svelte as opposed to generating DOM components.

I'm not really sure how Svelte, React or Vue allow for easier event handling. I mean, what's harder with standard events in Vanilla JS? Sure, it's not perfect, but what exactly is easier in Svelte, React and Vue that makes the trade-off with VanillaJS a reasonable one?
Some more questions, if you don't mind:
1. I see that the event interface specifies detail with `id` and `value` fields. What is the reason for using this? The underlying event already has a target, which will have the id and the value fields anyway. Are the widget's in this system so different that they have different id fields to the DOM elements?
2. There does not appear to be a field in the emitted event for the event sub-name (other than the custom name in the event structure itself). What if a component needs to emit something other than a "click" event? Ordinarily we'd get the event name from the event itself, so the handler knows whether it is being called on "focus", "click" "activate", etc. This information is lost with a custom event.
3. I'm still confused why you can't emit DOM elements; I mean, if you said "can't do two-way data binding" or something along the similar lines, it'd (maybe) make sense, but your response makes me think that you have not even considered it. I feel, maybe wrongly, that this library is both unnecessarily crippled and over-engineered - it targets spaghetti-as-a-pattern React, but not the hierarchical DOM?

This is something I rarely use in Vue anymore. I think back in the day, when Angular first emerged and pushed these sort of frameworks, there was a philosophy towards making components embed in code as if they were HTML native elements, and not needing to write JS around the event. If I remember correctly, providing a value field isn't asking it for the value of the event. It's specifying which value in memory should be set to the output of the event... But my memory is dodgy on that. It's confusing and I rarely see it used these days, but maybe that's reflective on the projects I've worked on.

Can you expand on the usecase here? Ordinarily, at least in Vue, there's no need to know the name of the event currently being triggered. The component emits a "change" event (or whatever you call it) and the parent component, when setting up the child component, will specify some sort of 'on-change' attribute that listens for the 'change' event and says which function should be evoked as the callback to it. So basically, instead of having to write `document.getElementById('foo').on('change', respondToFoo)`, you simply write `on-change='respondtoFoo'` directly on the element in the HTML.
It's not the world's biggest win, but it does reduce the amount of code our eyes having sift through in reading the JS, and attaches the event details directly to the element(s) they relate to, which I've found to be more readable.

You can, at least in Vue, but it's working against the grain. There's two reasons why:
1. Separation of presentation and state. These frameworks like to keep the HTML/DOM as simple presentation tools, and store logic and data separately. So when triggering events, we want to be emitting the important data as data, and not be concerned with the presentational layer from which that data may have originated.
2. Reusability of components. Emiting dom elements creates a more tightly coupled environment where there are a lot of expectations of the object being emitted (and little assurance as to what that object contains). By only exposing data and leaving the DOM element behind, it's easier for invoking components to use that data without having to hold expectations of the data structures being passed through.
