Quarkus Core Guidelines

Apply Quarkus core guidelines for CDI beans, configuration, profiles, and lifecycle.

What is covered in this Skill?

  • @QuarkusMain and application entry (when custom main is needed)
  • CDI scopes: @ApplicationScoped, @Singleton, @Dependent; bean disambiguation (@Default, @Alternative, @Named)
  • Constructor injection with @Inject
  • CDI interceptors (@Interceptor, @InterceptorBinding) for cross-cutting concerns
  • CDI events: @Observes StartupEvent / ShutdownEvent, @ObservesAsync for async dispatch
  • Programmatic injection with Instance for dynamic bean selection
  • @ConfigMapping and structured configuration with Bean Validation (@Valid)
  • Profile-specific properties (%dev, %test, %prod) and @IfBuildProfile
  • Startup and shutdown observers (@Startup, @PreDestroy)
  • Virtual threads with @RunOnVirtualThread (Java 21+)
  • Native-image safety: @RegisterForReflection, @DisabledOnNativeImage

Scope: Apply recommendations based on the reference rules and good/bad code examples.
