Normalize Components

Refactoring large React components involves decomposing files exceeding 300 lines into focused sub-components and extracting stateful logic into custom hooks to enforce separation of concerns and improve code quality.

You need to extract custom hooks when React components exceed 300 lines and contain complex stateful logic, isolating business logic from UI to enforce separation of concerns and improve maintainability.

The best way to break down a monolithic React component is through systematic decomposition and hook extraction, splitting structures into focused sub-components like UserProfileHeader and custom hooks like useFetchUserData.

Component decomposition targets React components exceeding 300 lines. While smaller files can be decomposed, this workflow specifically analyzes and validates refactoring based on the 300-line threshold to address maintainability issues.

To ensure functionality is preserved during React component decomposition, the workflow includes validation steps after hook extraction and component splitting to verify that code quality and original behavior remain intact.
