Can I use this for both Express and Fastify?

Absolutely. The skill provides optimized configurations and best practices for both the minimalist Express framework and the high-performance Fastify framework.

Is database integration included?

Yes, it provides repository patterns for SQL (PostgreSQL) and general data access logic that can be adapted for NoSQL databases.

What architectural patterns are emphasized?

It focuses on Layered Architecture (separation of concerns between transport, logic, and data layers) and Dependency Injection for better testability.

How does it handle security and validation?

It includes implementations for Helmet security headers, CORS configuration, JWT authentication, and Zod-based schema validation for request bodies and parameters.

Does this skill support TypeScript?

Yes, all patterns and code examples are designed for TypeScript to ensure type safety across controllers, services, and data layers.

API Development

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

This skill provides comprehensive architectural guidance for developing robust Node.js server-side applications. It streamlines the creation of RESTful APIs and microservices by enforcing proven patterns like layered architecture (Controller-Service-Repository), dependency injection, and centralized error handling. Whether using minimalist frameworks like Express or high-performance options like Fastify, the skill ensures best practices for security, authentication, and database integration are consistently applied, resulting in maintainable and testable codebases.
