React and Vue are both coming, in case you haven't seen already: https://tailwindui.com/react-and-vue-support/

Ah, yeah component makers are in a hard spot right now. You can't really write a 'generic' component easily and have to take a bet on using whatever JS framework is in vogue--react, vue, etc. It's not easy for a react project to pick up a vue component and use it or vice-versa. Even ignoring the framework incompatibilities, it also requires your component users to now buy in to the whole bundler game.

You could work around this by sticking with a generic, simpler framework like good ole jQuery. But now your framework users in react, vue, etc. are mad that they need to pull in kilobytes of JS that's doing what their framework already does.

So... as a component author a bundle of HTML and bring your own logic is kind of the only low-level option that's ubiquitous. Things might get better with web components, but it's not all there yet.

Ionic approaches this problem with stencil. So the ionic components can be used by not only angular projects, but also react / vue / vanilla js

Maybe they're hoping the community creates the framework-specific implementations?

Yes thats the intent. They handle only styling and framework integrations are upto the community

Inspect element - copy and paste with the Alpine JS intact.

Thank you. That's all it seems to be to me, and when people say "look at these components", it seems like they've not seen value in vuetify, for example.
