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?

Answer 2

Doing either File > Settings > Languages & Frameworks > JavaScript > Libraries or Click the face in the bottom right corner of the IDE > Libraries in scope. You can Add new libraries that are used for highlighting and code completion. If you are using NPM it's handiest to just add the entire node_modules directory so WebStorm will know about any other packages you install. Or if you don't want to do that, or you don't use NPM, you can just add the koa directory.

Depending on how you create your project I think WebStorm can automatically add the node_modules directory. At least some of my projects have done so without me explicitly doing this.
