How does this skill handle asynchronous middleware?

It includes an asyncHandler wrapper that ensures any errors occurring in asynchronous middleware are correctly caught and passed to the next error-handling middleware.

Does it support Role-Based Access Control (RBAC)?

Absolutely, it includes specialized factory functions for checking user roles after authentication to restrict access to specific API routes.

Can I use this for input validation?

Yes, the skill provides patterns for using the Zod library to validate both request bodies and query parameters, returning standardized 400 Bad Request responses for failed validations.

Is there a way to standardize API responses?

Yes, the skill features a Response Wrapper pattern that extends the Express response object with helper methods like res.success() and res.error() for consistent JSON outputs.
