Hi!
I'm afraid it looks like the motor draws around 60mA, which is too much for the Puck to output directly. You're going to need to add a transistor or FET to amplify the Puck's signal.
Adafruit themselves will have some good parts/suggestions. As a simple device that's massive overkill you could use this: https://www.adafruit.com/product/355
There should be smaller ones around, but that one will turn pretty much anything on or off from Puck.js :)
One thing to note is the CR2032 battery itself isn't meant to provide anywhere near 60mA - so while it might work, really you ought to use a bigger battery because it'll flatten itself in no time :)
