Enforces enterprise-grade NestJS architectural patterns, dependency injection standards, and Drizzle ORM integration for robust backend development.

This skill provides comprehensive guidance for building scalable NestJS applications by enforcing modular architecture, strict dependency injection scoping, and standardized error handling. It automates the implementation of best practices such as DTO validation with class-validator, custom exception filters, and the repository pattern using Drizzle ORM, ensuring codebases remain maintainable, testable, and aligned with official documentation and industry standards.

Key Features

01Optimized dependency injection scoping (Singleton, Request, Transient)
02Drizzle ORM integration via the repository pattern for type-safe data access
03Strict modular architecture enforcement and domain encapsulation
04Standardized error handling with custom exception filters and domain errors

06Automated DTO validation using class-validator and class-transformer

Use Cases

01Refactoring legacy NestJS code to remove anti-patterns like circular dependencies
02Implementing type-safe database layers using Drizzle ORM within the NestJS provider system
03Architecting new NestJS microservices or monolithic backends with proper encapsulation
