Refactor Code for your Express project
Expert refactor code for Express applications. We find and fix Express-specific bugs and security issues that affect production apps. From $19.
Express refactor code issues we find
Common refactor code problems specific to Express applications.
No helmet middleware for security headers
Express apps without the helmet middleware are missing critical security headers like Content-Security-Policy, X-Content-Type-Options, and HSTS, leaving the app vulnerable to common web attacks.
Missing input validation and sanitization
Request body, query params, and URL params used directly without validation. No express-validator, zod, or joi — enabling injection attacks and unexpected crashes.
Unstructured error handling
No global error-handling middleware. Errors either crash the process, leak stack traces to clients, or get silently swallowed with no logging.
CORS set to allow all origins
The cors() middleware called with no options, defaulting to allowing requests from any website — a security risk for APIs that handle user data.
No request size limits
express.json() without a size limit allows attackers to send massive payloads that consume all server memory and crash the process.
Secrets hardcoded in source files
Database URIs, API keys, and JWT secrets written directly in the code instead of loaded from environment variables. They end up in Git history.
What our Express 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Removing unused packages, updating outdated dependencies, and consolidating redundant libraries.
