 [Vue.js](https://vuejs.org) is a quiet, very popular JavaScript framework with an impressive set of features, a solid community, and MIT license.  Don't tell anybody, but I think I might even like it better than React.  With all this, Vue deserves its own set of helpers for `R`, just like [`d3r`](https://github.com/timelyportfolio/d3r) and [`reactR`](https://github.com/react-r/reactR).
