@vuedx/typescript-plugin-vue provides a great experience in VS Code, especially if some of your *.vue SFC export more than default.

Sadly it seems plugins aren't used when building with tsc and so I get many errors at build time, which reduces the usefulness of this plugin a lot.

I'm building with Rollup and rollup-plugin-typescript2, is there any way to make the magic work when building as well?
