Performance for your Codex CLI-built React app
Expert performance for React apps built with Codex CLI. We audit Codex CLI-generated React code for performance issues. From $19.
Codex CLI issues we find in React projects
Problems specific to Codex CLI's code generation patterns when building React apps.
API keys and secrets written directly into generated source files
Codex CLI generates code with placeholder credentials that developers often replace with real values inline, leaving secrets committed to version control. There is no .env scaffolding or secret management setup by default.
No authentication or authorization on generated API endpoints
When Codex generates Express or FastAPI backends, routes are created without middleware for authentication, meaning every endpoint is publicly accessible immediately after deployment.
Single-file output breaks apart for any real project structure
Codex frequently outputs all logic into one or two files rather than organizing code into modules, services, and utilities — making the result hard to maintain and extend as the codebase grows.
React performance issues we check for
Performance-specific React problems that need attention before production.
Unnecessary re-renders
Missing React.memo, useMemo, and useCallback cause components to re-render on every parent update, degrading performance.
Large bundle size
Importing entire libraries, unused dependencies, and no code splitting result in slow initial page loads.
