nestjs-best-practices SKILL.md skillA

nestjs-best-practices from giuseppe-trisciuoglio/developer-kit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add giuseppe-trisciuoglio/developer-kit/nestjs-best-practices@git:20260324.a02e282

Pins git:20260324.a02e282 in mdr.lock. Pin the fingerprint instead.

Provides comprehensive NestJS best practices including modular architecture, dependency injection scoping, exception filters, DTO validation with class-validator, and Drizzle ORM integration. Use when designing NestJS modules, implementing providers, creating exception filters, validating DTOs, or integrating Drizzle ORM within NestJS applications.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# NestJS Best Practices

## Overview

Grounded in the [Official NestJS Documentation](https://docs.nestjs.com/), 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
- Use `forwardRef()` only as a last resort for circular dependencies; prefer restructuring
- Group related controllers, services, and repositories within the same module
- Use a `SharedModule` for cross-cutting concerns (logging, configuration, caching)

See `references/arch-module-boundaries.md` for enforcement rules.

### 2. Dependency Injection

Choose the correct provider scope based on use case:

How to install

The exact contents, by fingerprint

mdr add giuseppe-trisciuoglio/developer-kit/nestjs-best-practices@sha256:b005b2213009c3b9

The line at the top of this page pins the label git:20260324.a02e282, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
