RingApi VS reitit

From what I know, I don't believe there's a way to establish a proper VoIP connection aside from the Ring app itself. The following links are neat if you haven't found them already but probably not what you're after, u/spornerama. It's a from python library but it seems the ring doorbells can be accessed via HTTP methods: https://github.com/dgreif/ring/wiki/SIP-Communication. Also see this .net library https://github.com/KoenZomers/RingApi.

I would build the CLJS for your game logic. Then I would build the backend server separately with API endpoints your front end to talk to. https://github.com/metosin/reitit is a pretty good option.

A significant feature of reitit is that routes are composed of simple vectors and maps. That means you can pre-process that data structure however you want before building the router.

You might look at the examples on the Reitit page. Reitit seems to be the emerging library for routing, and it does get you most of the way there, no matter which direction you are looking to go..

for runtime validation & coercion, you can use the pedestal-utilities from reitit which support all of spec, schema and malli. For dev-time var instrumentation (static & dynamic), there are several ways to add those to existing or 3rd party codebases.
