How does it handle API error responses?

The skill implements a global exception handler using @RestControllerAdvice to ensure all errors return a consistent JSON structure with status codes and timestamps.

Does it include guidance for large data sets?

Yes, it provides implementation patterns for Spring Data Pagination and Sorting to handle large result sets efficiently and prevent performance issues.

Does this skill support Java records for DTOs?

Yes, it specifically encourages using Java records (JDK 16+) or Lombok @Value for creating immutable DTOs and API contracts.

Can I use this for refactoring existing projects?

Absolutely. It is designed to help review and refactor existing Spring Boot controllers to meet modern REST standards and improve architectural layering.

API Development

Implements production-grade REST API design patterns and best practices for Spring Boot applications.

About

This skill provides Claude with the specialized knowledge required to build, review, and optimize RESTful APIs within Spring Boot projects, ensuring strict adherence to industry standards. It covers essential components including resource-based URL design, proper HTTP method usage, immutable DTO patterns, and global exception handling. By integrating these patterns, developers can ensure their APIs are consistent, maintainable, and secure while following architectural best practices like constructor injection and thin controllers to separate business logic from the web layer.

Key Features

Pagination, sorting, and HATEOAS implementation patterns
Resource-based URL and HTTP method standardization
Global exception handling with standardized error responses
1 GitHub stars
Jakarta validation integration for early input checking
Immutable DTO implementation using Java records or Lombok

Use Cases

Designing new microservice API contracts with standardized request/response models
Automating code reviews to ensure RESTful compliance and architectural consistency
Refactoring legacy controllers to implement DTOs and global error handling
