ghee
ghee is an ES6 based wrapper/helper for Slack's official client. It is specifically built to be used with ES7 decorators to make defining methods the bot can respond to easy to define without much overhead.
Why "ghee"?
It started off as the basis for ghebot, a bot to assist in monitor and alerting for GitHub Enterprise. Ghee is now the underlying framework for ghebot. Also, it's clear to use and smooth as butter.
