How can I deploy this on Inline Cloud Functions for Firebase?

[gskohner]

I would like to use this without a separate fulfillment endpoint URL Hosted on Google App Engine

You need to host the fulfillment logic on a server. You are free to use any hosting service that supports Node.js. You will have to make minor changes to the project to work on other platforms runtime.

Is there a way to adapt this to use the new inline Cloud Functions for Firebase?

[LeonNicholls]

There are a bunch of dependencies, so I'm not sure that would work.
