Building a production-ready REST API involves selecting a framework like Express or NestJS, designing database schemas in PostgreSQL, implementing authentication via JWT or OAuth 2.1, adding unit and integration tests, and deploying with Docker and CI/CD pipelines. This Skill covers the full architecture from API design through monitoring.

Security best practices include implementing OAuth 2.1 and JWT for authentication, applying role-based access control (RBAC), validating and sanitizing all inputs, using HTTPS, managing secrets securely, and regular security testing. This Skill provides guidance on OWASP Top 10 vulnerabilities and how to address them across Node.js, Python, Go, and Rust backends.

Query optimization involves indexing, using efficient SQL patterns, and analyzing execution plans. Caching strategies use Redis or in-memory stores to reduce database load. This Skill covers both techniques for improving response times and throughput in production systems running PostgreSQL, MongoDB, or similar databases.

Yes. This Skill covers designing and implementing GraphQL and gRPC APIs alongside REST, including authentication, testing, and deployment considerations. Framework support includes NestJS and FastAPI for GraphQL, and Go or Rust for gRPC services.

CI/CD setup involves automating tests, linting, and builds through platforms like GitHub Actions or GitLab CI, containerizing with Docker, and orchestrating with Kubernetes or managed services. This Skill provides end-to-end deployment and observability guidance for production environments.

This Skill supports Node.js with Express and NestJS, Python with FastAPI and Django, Go with Gin, and Rust. Each language includes guidance on framework selection, architectural patterns, testing strategies, and production deployment relevant to your use case.
