Get service deployable to something like `now`

[DSchau]

I think we should host with something like now. There are some considerations with this approach:

We will probably need to add in an endpoint to clear or reset data back to where it was.

We will probably need to add in (if it doesn't already exist) functionality specific to a user, i.e. authentication, so that we don't have one big hodge-podge of a database

Doing something like this will get us in a better state as far as being easier to set up and will also let this API be used with something non-local (e.g. CodeSandbox).
