Refactor Code for your NestJS project
Expert refactor code for NestJS applications. We find and fix NestJS-specific bugs and security issues that affect production apps. From $19.
NestJS refactor code issues we find
Common refactor code problems specific to NestJS applications.
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.
Missing exception filters
No global or controller-level exception filters, leaking internal stack traces and database errors to API consumers.
What our NestJS refactor code covers
Component restructuring
Breaking down god components into focused, reusable pieces with clear responsibilities.
Code deduplication
Identifying and consolidating repeated logic into shared utilities and hooks.
Architecture improvement
Separating concerns — UI from business logic, data fetching from rendering, config from code.
Type safety
Adding or improving TypeScript types to catch bugs at compile time instead of runtime.
Error handling patterns
Implementing consistent error handling, logging, and user-facing error messages throughout the app.
Dependency cleanup
Removing unused packages, updating outdated dependencies, and consolidating redundant libraries.
