Backend Implementation

Testing in Kotlin Spring Boot REST APIs involves running your full test suite with ./gradlew test, then targeting specific tests or integration tests as needed. This Skill provides testing patterns and validation commands to reduce boilerplate and ensure your API endpoints, services, and repositories work correctly together.

REST API structure in Spring Boot follows patterns for controllers, DTOs, services, and repositories with proper error handling and validation. This Skill guides you through implementing these layers, enforcing transactional patterns, database integration, and functional requirements so your backend stays maintainable and testable.

Validation and error handling in Spring Boot REST services require consistent patterns across your API. This Skill describes validation strategies, error handling approaches, and blocker scenario handling to ensure your services fail gracefully and provide meaningful responses to clients.

Yes. This Skill streamlines Kotlin backend API work by providing clear patterns and commands for API design, service implementation, testing, and database integration. It reduces boilerplate through established workflows for building, testing, and running Spring Boot projects locally with different profiles.

The build and run workflow builds JARs with ./gradlew build and runs your project locally using ./gradlew bootRun. This Skill guides you through build/run workflows, profile management, and integration with validation and testing patterns to support your full development cycle.

Database and repository integration in Spring Boot REST APIs requires proper transactional service patterns and repository guidelines. This Skill describes how to design repositories, handle transactions, and integrate database queries with your services and API endpoints following established best practices.
