Refactoring React components involves analyzing JSX nesting, duplicated logic, and state distribution to extract subcomponents and custom hooks with TypeScript interfaces. The process produces a clear split plan that restructures large files into reusable structures while maintaining organizational hierarchy and type safety.

Yes, refactoring React components preserves 1:1 runtime logic equivalence by keeping useEffect dependency timing, state initial values, event handling, and render conditions identical. A verification checklist validates conditional rendering, list keys, and side-effect dependencies after the refactor to guarantee no behavioral changes occur.

Yes, extracting TypeScript interfaces for custom hooks and subcomponents during a React refactor ensures type-safe extraction. The process follows file and hook conventions, preserves props and return shapes, and produces TypeScript interfaces for all extracted components and hooks to maintain strict type safety.

The best way to split tangled React state and side effects is through structural analysis to identify extraction candidates, followed by automated refactor planning. This separates mixed presentation, state, and side effects into well-organized custom hooks while keeping runtime behavior completely unchanged.

You should not refactor a React component if the structural analysis reveals deeply intertwined state flows or side effects that cannot be separated without altering useEffect dependency timing. The refactoring process prioritizes 1:1 logic preservation, so any extraction that risks behavioral changes should be avoided.
