How can I configure WebStorm to provide code completion for KoaJS?

Question

Currently, WebStorm reports that KoaJS's methods are undefined. It's a minor, yet persistent annoyance. I've searched on the net and I've searched through WebStorm's configuration dialogs to no avail.

Does anyone use WebStorm with KoaJS and have intellisense/code completion working properly?
