are there any docs available for how the npm environment is specified for graphcool functions. i'm just looking at the pusher module example here: https://github.com/graphcool/modules/blob/master/messaging/pusher/src/triggerPusherEvent.js it does

require('pusher')

and wondering if I write my own modules and have npm deps, where do I specify them?

Afaik, current plan is to move to a package.json (like webtask) to specify exact dep versions.
