Express app built with Bolt.new? Let’s review it.
Expert code review for Express apps built with Bolt.new. We find Bolt.new-specific bugs, fix Express security issues, and optimize performance. From $19.
Bolt.new issues we find in Express projects
Problems specific to Bolt.new's code generation patterns when building Express apps.
Hardcoded credentials in source
Bolt frequently embeds API keys, database URLs, and service credentials directly in source files rather than using environment variables.
No authentication or authorization
Bolt prototypes rarely include auth. Routes and API endpoints are completely unprotected, allowing anyone to access or modify data.
Incomplete error handling
Happy-path-only code that crashes on edge cases. Network failures, empty states, and invalid data cause unhandled exceptions and blank screens.
Missing loading and error states
Async operations show no loading indicators, and failed requests show no error messages — leaving users staring at a blank or frozen screen.
Express issues we check for
Common Express problems that affect production readiness.
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.
