React Component No Longer Renders After Cursor Refactoring
A React component that was previously rendering correctly now fails to display or shows blank/error states after Cursor refactored the component code.
The component may have missing state, incorrect hooks, or broken rendering logic.
Error Messages You Might See
React Hook "useState" is called conditionally
Component is not a function
Unexpected token <
Cannot read property of undefined
Common Causes
- useState or useEffect hook calls moved inside conditional logic (invalid hook rules)
- Required props no longer passed from parent after refactoring
- Component export changed to default export when named was needed
- useCallback/useMemo dependency arrays incomplete or removed
- Removed JSX return statement, leaving undefined return
How to Fix It
Verify hooks are at top level, not in conditionals. Check console for React errors and prop warnings. Ensure component is exported correctly. Add console.log() at render start. Verify all required props have default values or are properly passed.

What are React Hook rules?
Call hooks at top level, not in conditionals. Only call hooks from React functions. Use ESLint plugin to catch violations.
How do I debug React rendering?
Use React DevTools browser extension. Check console for warnings. Add console.log in render.
