It'd be awesome to have a webpack loader so I could automatically get runtime validation of flow types from libraries.

My use case is that I want to validate DraftJS state on the server, which I'd love to do like this:

// Note: .js.flow file
import { RawDraftContentState } from 'flow-runtime-loader!draft-js/lib/RawDraftContentState.js.flow';

const storePost = (body) => {
  t.param('body', RawDraftContentState).assert(body); 
  return storePostInDb({ body });
}

Does something like that exist?

Or maybe this already works?

import type { RawDraftContentState } from 'draft-js/lib/RawDraftContentState.js.flow';

const storePost = (body: RawDraftContentState) => {
  return storePostInDb({ body });
}

@mxstbr this doesn't already exist but a webpack loader is definitely something I want, it'd solve a lot of the problems we have that come from babel's single-file-at-a-time approach.
