I currently have classic setup for my project (https://github.com/LanderDhaen/clantracker) where the back-end consists of NodeJS, Koa, Kysely and PostgreSQL and the front-end consists of SWR and Vite.

I've recently migrated to TS and I'm looking to go even further and migrate to Next but I'm struggling to get started.

My question is mostly about how to structure my application and if I should keep all the endpoints (and call them) or create actions that speak to the database directly (like shown in the tutorial).
