To implement JWT authentication, the backend-patterns skill provides guidance and code examples for establishing secure JWT and OAuth2 flows within your server-side systems. It demonstrates how to structure authentication logic for scalable and maintainable applications.

For scalable microservices, applying the Repository and Unit of Work database patterns ensures maintainable data access layers. This skill illustrates these patterns to help manage transactions and query logic effectively across distributed services.

You need the Circuit Breaker pattern in microservices architecture to prevent cascading failures when downstream services become unresponsive. This skill introduces the Circuit Breaker alongside the API Gateway pattern to build robust fault-tolerant systems.

The Cache-Aside pattern improves backend performance by loading data into the cache only when requested, reducing unnecessary database calls. This skill explains Cache-Aside and Write-Through patterns to optimize your system's response times.

Yes, REST and GraphQL principles can guide different parts of your API design. This skill covers both RESTful and GraphQL API principles, providing best practices to help you design scalable and secure server-side interfaces.

To handle error responses, you should implement structured error formats and correct HTTP status code mappings. This skill provides structured error response examples to ensure consistent and maintainable error handling across your backend architecture.
