Does this skill support both Express and Fastify?

Yes, it provides optimized boilerplate and implementation patterns for both the minimalist Express.js framework and the high-performance Fastify framework.

Can I use these patterns for microservices?

Absolutely. The lightweight DI container and separation of concerns make these patterns ideal for building independent, scalable microservices.

How does it handle security and authentication?

It includes standardized middleware patterns for JWT authentication, role-based access control (RBAC), and security headers using tools like Helmet and CORS.

Is the code generated by this skill type-safe?

Yes, all patterns are built with TypeScript and include Zod schema validation to ensure end-to-end type safety from the request body to the database layer.

What is the primary architectural pattern used?

The skill emphasizes a Layered Architecture (Controller-Service-Repository) and Dependency Injection to separate concerns and ensure the codebase is modular and testable.

API Development

Implements scalable, production-ready Node.js backend architectures using Express, Fastify, and industry-standard design patterns.

Node.js Backend Patterns provides a comprehensive framework for building robust, maintainable server-side applications. It guides users through implementing structured architectural patterns like Controller-Service-Repository and Dependency Injection to ensure code remains testable and organized as it scales. The skill covers critical production requirements including JWT authentication, role-based access control, type-safe validation with Zod, and optimized configurations for both Express and Fastify frameworks. It is an essential resource for developers moving from basic scripts to professional-grade microservices and RESTful APIs.
