I believe this is already supported (vue3 still has all the features of vue2 unless noted otherwise)
https://vuejs.org/v2/guide/render-function.html#JSX

It's not frequently mentioned, but the composition API's setup method can be used alongside the existing api as well.. there's a blurb here about how things resolve:

Is "vue-jsx" in "vue 3.0" particularly close to "react-jsx"?

The "vue-jsx" in "vue 2.0" is not very popular.

What does "jsx" look like in the future "vue 3.0"?

Unless someone can correct me, I believe jsx is jsx.. it's exactly the same everywhere.

The "vue-jsx" in "vue 2.0" is not very popular.

That's subjective, as are most of the reasons stated for opening this issue, so I can't really comment on any of that. You might find jsx easier to learn and use.. personally, I don't, but it obviously has its merits so I'm glad its an option for components that can be better expressed using it.

Also, vue's <template> is not using mustache... both use curly braces, but they're not remotely the same thing and you'll have a very hard time building a vue template if you're reading mustache docs. 😄

https://github.com/developit/htm <- this is NOT JSX. If that's something you want, it already exists for Vue 2 (and can be easily updated for Vue 3): https://github.com/egoist/vue-html
