Is there support for caching?

Yes, it includes patterns for Redis-based caching layers and the Cache-Aside pattern to improve response times for frequently accessed data.

What frameworks does this skill support?

While the code examples focus on Node.js, Express, and Next.js, the architectural patterns (like Repository and Service layers) are applicable to almost any server-side environment.

Does it include security best practices?

Absolutely. It covers JWT token validation, Role-Based Access Control (RBAC) via Higher-Order Functions, and centralized error handling to prevent sensitive data exposure.

How does this handle long-running tasks?

The skill includes patterns for background jobs and simple queue management, allowing you to process heavy tasks without blocking the main API response.

Can this help with database performance issues?

Yes, it provides specific implementation patterns for preventing N+1 query problems, managing database transactions, and selecting only necessary data columns to reduce load.
