What validation library is recommended with this skill?

The skill primarily utilizes Zod for robust, schema-based request validation to ensure data integrity before reaching your controllers.

Is error handling centralized?

Yes, it includes patterns for global error handling middleware that catches asynchronous errors and provides consistent JSON responses.

How does it handle API security?

It implements industry-standard security practices including Helmet for HTTP headers, CORS configuration, and JWT-based authentication.

Does this skill support TypeScript?

Yes, the skill is designed with TypeScript in mind, providing type-safe patterns for Request, Response, and custom middleware objects.

Can I use this for existing Express projects?

Absolutely. The skill provides modular patterns that can be used to refactor specific routes or add new validated endpoints to existing codebases.
