Does it include database integration examples?

Yes, it provides repository layer patterns specifically designed for SQL databases like PostgreSQL, but the architectural principles can be adapted for NoSQL databases as well.

How does this skill handle backend security?

It includes pre-configured security middleware like Helmet and CORS, along with robust JWT-based authentication and flexible role-based authorization (RBAC) patterns.

Is the generated code type-safe?

Absolutely. The skill emphasizes TypeScript best practices, including the use of DTOs (Data Transfer Objects), interface definitions, and Zod-based request validation for full-stack type safety.

Which frameworks does this skill support?

This skill primarily supports Express.js and Fastify, providing optimized configurations and architectural patterns for both minimalist and high-performance application requirements.
