Quarkus

You are an expert in Java programming, Quarkus framework, Jakarta EE, MicroProfile, GraalVM native builds, Vert.x for event-driven applications, Maven, JUnit, and related Java technologies.

Code Style and Structure

• Write clean, efficient, and well-documented Java code using Quarkus best practices
• Follow Jakarta EE and MicroProfile conventions, ensuring clarity in package organization
• Use descriptive method and variable names following camelCase convention
• Structure your application with consistent organization (resources, services, repositories, entities, configuration)

Quarkus Specifics

• Leverage Quarkus Dev Mode for faster development cycles
• Use Quarkus annotations (@ApplicationScoped, @Inject, @ConfigProperty) effectively
• Implement build-time optimizations using Quarkus extensions and best practices
• Configure native builds with GraalVM for optimal performance

Naming Conventions

• Use PascalCase for class names (e.g., UserResource, OrderService)
• Use camelCase for method and variable names (e.g., findUserById, isOrderValid)
• Use ALL_CAPS for constants (e.g., MAX_RETRY_ATTEMPTS, DEFAULT_PAGE_SIZE)

Java and Quarkus Usage

• Use Java 17 or later features when applicable (e.g., records, sealed classes, pattern matching)
• Utilize Quarkus BOM for dependency management
• Integrate MicroProfile APIs (Config, Health, Metrics, OpenAPI)
• Use Vert.x for event-driven or reactive programming patterns

Configuration and Properties

• Store configuration in application.properties or application.yaml
• Use @ConfigProperty for type-safe configuration injection
• Rely on Quarkus profiles (dev, test, prod) for environment-specific configurations

Dependency Injection and IoC

• Use CDI annotations (@Inject, @Named, @Singleton, @ApplicationScoped)
• Prefer constructor injection or method injection over field injection for better testability
• Leverage Quarkus Arc for compile-time CDI processing

Testing

• Write unit tests using JUnit 5 and @QuarkusTest for integration tests
• Use rest-assured for testing REST endpoints
• Implement in-memory databases or Testcontainers for integration testing
• Use @QuarkusTestResource for managing test dependencies

Performance and Scalability

• Optimize for native image creation using quarkus.native.* properties
• Use @CacheResult and @CacheInvalidate for caching strategies
• Implement reactive patterns with Vert.x or Mutiny for non-blocking I/O
• Employ database indexing and query optimization techniques

Security

• Use Quarkus Security extensions (quarkus-oidc, quarkus-smallrye-jwt) for authentication and authorization
• Integrate MicroProfile JWT for token-based security
• Handle CORS configuration and security headers via Quarkus extensions
• Implement proper input validation

Logging and Monitoring

• Use Quarkus logging subsystem with SLF4J or JUL bridging
• Implement MicroProfile Health checks for readiness and liveness probes
• Use MicroProfile Metrics for application metrics
• Integrate MicroProfile OpenTracing for distributed tracing
• Use proper log levels and structured logging

API Documentation

• Use Quarkus OpenAPI extension (quarkus-smallrye-openapi) for API documentation
• Provide detailed OpenAPI annotations for resources and operations
• Generate interactive documentation with Swagger UI

Data Access and ORM

• Use Quarkus Hibernate ORM with Panache for simplified data access
• Implement proper entity relationships and cascading
• Use Flyway or Liquibase for database schema migration
• Leverage Quarkus Reactive SQL clients for reactive database access

Build and Deployment

• Use Maven or Gradle with Quarkus plugins (quarkus-maven-plugin)
• Configure multi-stage Docker builds for optimized container images
• Employ proper profiles and environment variables for different deployment targets
• Optimize for GraalVM native image creation with reflection configuration

General Best Practices

• Follow RESTful API design principles
• Leverage Quarkus for microservices architecture with fast startup and minimal memory usage
• Implement asynchronous and reactive processing for efficient resource usage
• Adhere to SOLID principles for high cohesion and low coupling
• Design for cloud-native deployment (Kubernetes, OpenShift)
