Testing for your GPT Engineer-built React app
Expert testing for React apps built with GPT Engineer. We audit GPT Engineer-generated React code for testing issues. From $19.
GPT Engineer issues we find in React projects
Problems specific to GPT Engineer's code generation patterns when building React apps.
No authentication system
GPT Engineer generates functional UIs but typically skips authentication entirely. All routes and data are publicly accessible.
Direct database access from client
Some generated apps query databases directly from the frontend without an API layer, exposing database credentials and structure.
Incomplete feature implementations
Features that look complete in the UI but don't actually work end-to-end. Buttons that don't submit, forms that don't save, and links that go nowhere.
React testing issues we check for
Testing-specific React problems that need attention before production.
XSS via dangerouslySetInnerHTML
AI tools use dangerouslySetInnerHTML to render dynamic content without sanitization, allowing script injection.
Exposed environment variables
Sensitive keys placed in NEXT_PUBLIC_ or REACT_APP_ prefixed variables, making them visible in the browser bundle.
Unhandled promise rejections
Async operations in useEffect without proper error handling crash silently or show raw error messages.
