Using Volar internals to get codegen metadata

[dvh91]

I'm wondering if it's theoretically possible to use Volar internal in order to parse Vue 3 syntax with typescript into a structured component metadata like prop types, slots and general comments.

It'll be especially useful considering vue-styleguidist internal parsing tools doesn't support the new syntax and Storybook also relies on these internals.

See vue-styleguidist/vue-styleguidist#997 for further reference and the current state and plans of supporting the new syntax.

I think TypeScript TypeChecker API can do it, I planed to explore it when implement component preview feature.
