A few weeks ago I posted about my .NET 8 Minimal API Starter Kit (MongoDB). Today I'm launching the second edition — MongoDB + Keycloak.

It has everything from the first kit plus a fully pre-configured Keycloak authentication layer:

JWT Bearer configured via OIDC
Role-based authorization policies out of the box (Authenticated and AdminOnly)
OAuth2 Authorization Code + PKCE flow wired into Swagger — there's an Authorize button that actually works with real Keycloak tokens
Pre-built realm (realm-export.json) imported automatically at container startup — two test users already created with different roles, zero manual Keycloak configuration needed
401 and 403 return structured RFC 7807 ProblemDetails, not empty HTTP responses

docker compose up and the API, MongoDB, and Keycloak are all running.

Launch price is €45 — use code FIRSTXPEOPLE for €15 off.

Hello, I've been a .NET dev for a while and I kept starting every new API project by rebuilding the same foundation from scratch. Repository pattern, error handling, pagination, database and Docker setup.

So i made a new solution for my recurring problem with the basics, that solution is ".NET 8 Minimal API Starter Kit"

The core idea is a "BaseRepository" with 7 overridable hooks. You inherit it for each resource and only override what your domain actually needs — everything else (CRUD, pagination, validation flow) runs automatically. Adding a new resource takes minutes.

The full hook chain for "CreateAsync" runs in this order: validate → base mapping → "OnMapCreateAsync" (server-side enrichment) → DB insert → "OnMapDetailAsync". Every hook returns "ErrorOr<T>" so if anything fails the operation aborts before touching the database.

Happy to have feedback for things that might be missing for next versions and products.
