kaocha VS reitit

Full-featured test runner: https://github.com/lambdaisland/kaocha

If you install neil (https://github.com/babashka/neil), you can do `neil add test` which will automatically set up cognitect-labs/test-runner in your project. Then you can run tests with `neil test` (just an alias, you don't have to use it).

> I used Kit to bootstrap this project and the way it set up tests doesn't even work, but this was what most people recommended to me for starting a Clojure project

I don't really like the approach that Kit takes and prefer something more opinionated like Biff. I'd love to hear your feedback if you do end up trying out Biff.

run tests using kaocha.

But you can use other test runners, such as https://github.com/lambdaisland/kaocha

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.
