Performance for your Claude Code-built Node.js app
Expert performance for Node.js apps built with Claude Code. We audit Claude Code-generated Node.js code for performance issues. From $19.
Claude Code issues we find in Node.js projects
Problems specific to Claude Code's code generation patterns when building Node.js apps.
Over-permissive CORS configuration
Claude Code sometimes sets CORS to allow all origins during development and forgets to restrict it for production, allowing any website to make API requests.
Missing rate limiting
API endpoints are generated without rate limiting, allowing attackers to brute-force auth endpoints or abuse expensive operations.
Over-engineered abstractions
Claude Code creates multiple layers of abstraction, generic utilities, and design patterns for simple problems — making the code harder to understand and maintain.
Node.js performance issues we check for
Performance-specific Node.js problems that need attention before production.
Memory leaks
Event listeners not cleaned up, growing arrays/maps, and unclosed connections that gradually consume all available memory.
Synchronous blocking operations
File reads, crypto operations, or data processing on the main thread blocking all other requests.
