Do you have any plan to support frontmatter attributes in this loader too?
Currently, vmark-loader is returning vmark(data).component only, but I wondered if I pick attributes too.

Thanks for your nice project. vmark is what I wanted exactly.

Would be great to see an end-to-end example of this in a tiny Vue project.

If you're writing typescript Vue code, tsc will complain when you do import Doc from 'Doc.md'. You need to add a shim (ambient typescript module declaration) to tell tsc that a .md is a Vue component:

% cat src/shims-md.d.ts
declare module '*.md' {
  import Vue from 'vue'
  export default Vue
}

Otherwise when building, you will get errors about missing components.
