react.js views

I am no web dev guru - would it make sense to use react as the templating engine in some cases?

with react serverside rendering, I suppose you wouldn't even need a views dir, except perhaps an error page or 404?

what I am really wondering is, does this exist?

```express --view=react /tmp/foo && cd /tmp/foo```

and if we use React for serverside rendering, do we just discard the hbs stuff?
