Performance for your Bolt.new-built Express app
Expert performance for Express apps built with Bolt.new. We audit Bolt.new-generated Express code for performance issues. 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.
Express performance issues we check for
Performance-specific Express problems that need attention before production.
Blocking the event loop
CPU-intensive operations like JSON parsing of large files, image processing, or heavy computation done on the main thread, blocking all other requests.
