Hi Bryan,

Following my email, here is the issue you requested. It could be great to be able to integrate Flow (as it is now OpenSource) in Codekit as it checks static type for JavaScripts files. Here is the link of the blog post: https://code.prod.facebook.com/posts/1505962329687926/flow-a-new-static-type-checker-for-javascript/
