I think the cool part is that that you could do all of this stuff and not have to worry about any of the infrastructure.

The node package only works inside of the hosting environment. You're paying that much money for everything to be hosted. It says in the docs that there's no local development environment.

You will always have to worry about the infrastructure. This might be a view of hosted development's future, but every abstraction will leak. When the day the your app gets more sign ups in an hour than you have in your userbase, you'd better understand your env as deeply as possible.
