NestJS Authentication

概要

This skill provides specialized assistance for designing, implementing, and refactoring authentication modules within NestJS TypeScript backends. It guides the creation of secure login and signup flows, manages JWT access and refresh tokens, and enforces granular security through custom guards and decorators for Role-Based Access Control (RBAC). By following NestJS best practices and Passport.js patterns, it ensures that API endpoints are protected and sensitive data like passwords and secrets are handled correctly using environment-based configurations.
