NestJS Best Practices
Overview
Grounded in the Official NestJS Documentation, this skill enforces modular architecture, dependency injection scoping, exception filters, DTO validation with class-validator, and Drizzle ORM integration patterns.
When to Use
- Designing/refactoring NestJS modules or dependency injection
- Creating exception filters, validating DTOs, or integrating Drizzle ORM
- Reviewing code for anti-patterns or onboarding to a NestJS codebase
Instructions
1. Modular Architecture
Follow strict module encapsulation. Each domain feature should be its own @Module():
- Export only what other modules need — keep internal providers private
