Build production-ready Express.js REST APIs by implementing routing, middleware composition, request/response handling, authentication, input validation, and error handling. This Skill guides you through architecture patterns, security hardening, testing, performance optimization, logging, and deployment strategies needed for scalable, robust applications.

Middleware patterns in Express.js handle security validation, authentication, and request processing. This Skill covers middleware composition, input validation best practices, and security hardening techniques that prevent common vulnerabilities in REST APIs and microservices.

Request validation in Express.js sanitizes and validates incoming data before processing. This Skill provides patterns for input validation, error handling, and security best practices to ensure your API rejects malformed or malicious requests reliably.

Yes. Express.js supports REST APIs, microservices, web servers, and real-time applications. This Skill covers production deployment patterns, routing, middleware, and logging strategies tailored for these architectures.

Production deployment for Express.js includes logging, monitoring, performance optimization, and security hardening. This Skill covers deployment patterns that satisfy technical requirements for scalable, secure, and maintainable applications in production environments.

Error handling in Express.js REST APIs requires consistent middleware patterns and proper HTTP status responses. This Skill guides you through implementing robust error handling, logging, and recovery strategies that improve API reliability and debuggability.
