NestJS Guards & Interceptors
Implements secure authentication guards and powerful request-response interceptors for NestJS applications.
This skill provides specialized patterns and best practices for managing cross-cutting concerns in NestJS. It enables Claude to implement robust security measures including JWT, session, and API key authentication guards, alongside granular Role-Based Access Control (RBAC). Additionally, it provides templates for interceptors that handle request/response transformation, advanced logging, and performance monitoring, ensuring your backend architecture remains consistent, secure, and observable.
