Calling Trello API from Meteor

I just ported the Trello client API to a Meteor package, in order to be able to authorize my application before making actual API calls from the server side (let’s just avoid the hassle of cross-site scripting).

The following snippet shows my client side flow for creating a Trello board; first I authorize against Trello, then I call a Meteor server method to perform the corresponding Trello REST API call:

Session.set("isWaiting", true)
# MuzHack's Trello app key
Trello.setKey(Meteor.settings.public.trelloKey)
# Have the Trello client lib display a popup wherein the user authorizes MuzHack's read-write access
Trello.authorize({
  type: "popup"
  name: "MuzHack"
  scope: { read: true, "write": true }
  success: ->
    logger.info("Trello authorization succeeded")
    token = Trello.token()
    Meteor.call('createTrelloBoard', inputValues.name, inputValues.desc, inputValues.org,
      token, (error, result) ->
        Session.set("isWaiting", false)
        if error?
          logger.warn("Server failed to create Trello board:", error)
          notificationService.warn("Error",
            "Server failed to create Trello board: #{error.reason}.")
        else
          logger.debug("Server was able to successfully create Trello board")
    )
  error: ->
    logger.warn("Trello authorization failed")
      Session.set("isWaiting", false)
})
