NestJS app built with Claude Code? Let’s review it.
Expert code review for NestJS apps built with Claude Code. We find Claude Code-specific bugs, fix NestJS security issues, and optimize performance. From $19.
Claude Code issues we find in NestJS projects
Problems specific to Claude Code's code generation patterns when building NestJS apps.
Over-permissive CORS configuration
Claude Code sometimes sets CORS to allow all origins during development and forgets to restrict it for production, allowing any website to make API requests.
Missing rate limiting
API endpoints are generated without rate limiting, allowing attackers to brute-force auth endpoints or abuse expensive operations.
Over-engineered abstractions
Claude Code creates multiple layers of abstraction, generic utilities, and design patterns for simple problems — making the code harder to understand and maintain.
Edge cases in complex logic
While Claude handles the main flow well, complex conditional logic sometimes has edge cases that produce incorrect results with unusual inputs.
NestJS issues we check for
Common NestJS problems that affect production readiness.
Missing authentication guards
Controllers and routes without @UseGuards decorators, leaving endpoints publicly accessible without any auth checks.
Incorrect dependency injection scope
Services registered with wrong scope (default singleton vs request-scoped) causing shared state between requests and data leakage between users.
Unvalidated DTOs
Data Transfer Objects without class-validator decorators or missing the global ValidationPipe, accepting any shape of input data.
Circular dependency issues
Modules importing each other in cycles, causing runtime errors or undefined injections that only surface in production.
