How does this skill help with NestJS circular dependencies?

It identifies common dependency loops and suggests refactoring strategies such as extracting shared logic into separate modules or correctly implementing forward references.

Does it support complex patterns like CQRS?

Absolutely. It provides implementation patterns for Commands, Queries, and Event Handlers to help decouple your business logic from your transport layer.

How does it improve controller readability?

It transforms 'fat' controllers into thin entry points by moving business logic into services and handling cross-cutting concerns through guards, interceptors, and pipes.

Can it help with DTO validation?

Yes, it automatically refactors request and response objects into DTOs using class-validator and class-transformer for robust runtime validation and type safety.

Acerca de

This skill empowers developers to transform legacy or disorganized NestJS codebases into exemplary, production-grade implementations. It specializes in identifying and resolving architectural smells like circular dependencies, 'god object' services, and Single Responsibility Principle (SRP) violations while implementing advanced NestJS patterns. Whether you need to reorganize modules for better encapsulation, implement CQRS for complex domain logic, or optimize DTO validation, this skill provides domain-specific guidance to ensure your backend is clean, readable, and follows industry best practices.
