Nestjs Code Review

This is a focused code reviewer for NestJS projects that catches the stuff that actually matters: dependency injection antipatterns, fat controllers with business logic leaking in, missing DTOs and validation pipes, guard implementations that belong in middleware, and module boundaries that make no sense. It works through your controllers, services, modules, guards, and interceptors, then spits out categorized findings (Critical, Warning, Suggestion) with actual code examples showing the fix. The validation checkpoint before finalizing is smart, it forces the review to drop subjective style nitpicks and stick to concrete, actionable problems. Use it before merging PRs or when you inherit a NestJS codebase and need to understand what's broken. Works with TypeORM, Prisma, and Drizzle patterns.

NestJS Code Review

Overview

Provides structured code review for NestJS applications. Findings categorized by severity (Critical, Warning, Suggestion) with actionable recommendations. Delegates to nestjs-code-review-expert agent for deep analysis.

When to Use

"review NestJS code", "NestJS code review", "check my NestJS controller/service"
Before merging pull requests or after implementing new features
Validating NestJS decorators, DI patterns, guard implementations
Architecture validation for NestJS modules and providers
Reviewing DTOs, pipes, interceptors, and database integration (TypeORM, Prisma, Drizzle)

Instructions

Identify Scope: Determine which NestJS files and modules are under review. Use glob and grep to discover controllers, services, modules, guards, interceptors, and pipes in the target area.
Analyze Module Structure: Verify proper module organization — each feature should have its own module with clearly defined imports, controllers, providers, and exports. Check for circular dependencies and proper module boundaries.
