NestJS app built with GitHub Copilot? Let’s review it.
Expert code review for NestJS apps built with GitHub Copilot. We find GitHub Copilot-specific bugs, fix NestJS security issues, and optimize performance. From $19.
GitHub Copilot issues we find in NestJS projects
Problems specific to GitHub Copilot's code generation patterns when building NestJS apps.
Insecure code patterns from training data
Copilot sometimes suggests patterns from its training data that are known to be insecure — like using eval(), innerHTML, or outdated crypto functions.
Hardcoded secrets in suggestions
Copilot occasionally suggests placeholder API keys or credentials that look real and get committed to version control.
Inconsistent code style across files
Different completions use different patterns — sometimes callbacks, sometimes async/await, sometimes .then(). The codebase becomes inconsistent over time.
Subtly incorrect logic
Copilot completions often look correct but contain off-by-one errors, wrong comparison operators, or missed edge cases that cause intermittent bugs.
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.
