Is there support for centralized error handling?

Yes, it features a centralized error-handling middleware using custom error classes and an async wrapper to ensure all route errors are caught and logged properly.

How does this skill handle input validation?

It implements Zod-based validation middleware that automatically parses and validates request bodies, query strings, and URL parameters against defined schemas.

Does it include protection against brute-force attacks?

Yes, it includes Redis-backed rate limiting patterns specifically designed for general API protection and stricter limits on authentication endpoints.

Why is the middleware order important in these patterns?

Express executes middleware sequentially; this skill emphasizes correct ordering—placing security and body parsers early and error handlers last—to ensure stability.

What authentication methods are supported by this skill?

The skill provides patterns for JWT (JSON Web Token) authentication, including Bearer token extraction, payload verification, and role-based access control (RBAC).

API開発

Implements production-ready Express.js middleware for authentication, validation, error handling, and security.

Provides a comprehensive set of middleware implementation patterns for Express.js applications, covering critical backend concerns such as JWT authentication, Zod-based input validation, centralized error handling, and Redis-backed rate limiting. It helps developers build robust, secure, and observable Node.js APIs by establishing standardized request-response lifecycles and protecting endpoints against common vulnerabilities, ensuring consistent behavior across the entire backend architecture.
