Testing for your Cursor-built Express app

Expert testing for Express apps built with Cursor. We audit Cursor-generated Express code for testing issues. From $19.

Cursor issues we find in Express projects

Problems specific to Cursor's code generation patterns when building Express apps.

highSecurity

Exposed API keys in client code

Cursor often places sensitive keys and secrets directly in client-side components or .env files without the NEXT_PUBLIC prefix distinction, making them accessible in the browser.

highSecurity

Missing input validation on API routes

Server actions and API routes generated by Cursor frequently accept user input without sanitization or schema validation, opening the door to injection attacks.

mediumBugs

Unhandled async errors

Cursor wraps code in try/catch inconsistently. Failed API calls, database queries, and file operations often crash the app silently or show raw error messages to users.

Express testing issues we check for

Testing-specific Express problems that need attention before production.

security

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.

security

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.

bugs

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.

Frequently asked questions

Can you testing my Cursor-built Express app?

Yes. We regularly handle testing for Express projects built with Cursor. We understand Cursor's code patterns and the specific Express issues they introduce. Our review covers the full stack from frontend to backend.

What Express testing issues does Cursor typically create?

Common testing issues in Cursor-generated Express code include: exposed api keys in client code, missing input validation on api routes, unhandled async errors. On the Express side, we often find: no helmet middleware for security headers, missing input validation and sanitization, unstructured error handling.
