Hi,

First of all: I really like the way you wrote this bridge - I was on my way of writing the same thing on my own so this is seriously cool to see. :)

I see that your code depends on bluebird - which is quite heavy when compared to native promises. It has the upshot of being available anywhere, but perhaps you'd consider moving to native promises with some polyfill like any-promise and add bluebird as optional dependency?

I would be happy to help.
