Nestjs Expert

If you're scaffolding NestJS backends and tired of wiring up modules, controllers, and services by hand, this gets you enterprise patterns out of the box. It handles the full stack: dependency injection setup, DTO validation with class-validator, JWT authentication guards, TypeORM or Prisma integration, and proper unit test boilerplate. The workflow is structured around analyze, design, implement, secure, verify, test, which keeps you from shipping half-configured modules. Particularly strong on the testing side with concrete mocking patterns for repositories. Created by Jeffallan, currently at version 1.1.0. Works well alongside fullstack-guardian and test-master if you need broader coverage beyond the NestJS layer.
