Expert performance for JavaScript apps built with Replit Agent. We audit Replit Agent-generated JavaScript code for performance issues. From $19.
Replit Agent issues we find in JavaScript projects
Problems specific to Replit Agent's code generation patterns when building JavaScript apps.
Secrets stored in Replit environment
API keys and credentials stored in Replit's secrets manager don't transfer when you export the project. Developers often hardcode them as a workaround, creating security risks.
No HTTPS or security headers
Replit's development environment doesn't enforce HTTPS or set security headers. Apps deployed without proper configuration are vulnerable to man-in-the-middle attacks.
Database connection instability
Replit's hosted databases can disconnect unexpectedly. Without connection pooling and retry logic, apps crash or lose data during these interruptions.
JavaScript performance issues we check for
Performance-specific JavaScript problems that need attention before production.
Memory leaks from closures and listeners
Event listeners, intervals, and closures that capture large objects are never cleaned up, causing memory consumption to grow over time.
