How does it help with database performance?

It provides specific patterns for query optimization, indexing, and prevents the common N+1 query problem through batch fetching logic.

Can it help with error handling?

Absolutely. It features centralized error handling patterns, custom API error classes, and resilient retry logic with exponential backoff.

Does it include security best practices?

Yes, it includes implementation guides for JWT token validation, middleware-based authentication, and Role-Based Access Control (RBAC).

What frameworks does this skill support?

It focuses primarily on Node.js, Express, and Next.js API routes, providing patterns applicable to most modern TypeScript/JavaScript environments.
