Just verifying: it would seem from this https://github.com/hax/refactor/issues/45 (which shows the plug-in hasn't worked since April) that this project is dead. I'll take a lack of response as confirmation ;)
No, this plugin is not dead. And I always eat the dog food, so I can confirm both js-refactor and coffee-refactor still work on the recent Atom 1.19.x.
