Does it handle API security?

Yes, it includes patterns for essential security middleware like Helmet and CORS, as well as robust JWT-based authentication and role-based access control.

Which frameworks does this skill support?

It primarily supports Express.js and Fastify, providing optimized configurations, middleware, and architectural patterns for both frameworks.

Can I use this for microservices?

Absolutely. The modular, layered architectural patterns recommended by this skill are ideal for building independent and scalable microservices.

Does it include database integration?

Yes, it provides repository patterns for data access layers, demonstrating how to integrate SQL (PostgreSQL) and NoSQL databases effectively.

Is TypeScript supported?

Yes, all provided patterns, types, and code examples are fully optimized for TypeScript to ensure type-safety throughout your backend.
