To refactor duplicate TypeScript types, scan common locations like src/components and src/hooks to identify redundancies, unify definitions using extends, Pick, and Omit, and extract them into a centralized src/types/ library to reduce surface area and improve reuse.

The best way to extract inline TypeScript types is to move them into a centralized src/types/ directory, which creates a stable type library. This process updates the type-index.json to reflect changes and improves maintainability in collaborative projects.

Unify duplicate type definitions by applying TypeScript utility types like extends, Pick, and Omit to minimize surface area. This approach composes shared base types rather than duplicating properties, improving code reuse across the project.

Yes, you can automatically scan src/components, src/hooks, src/pages, and src/types for inline type definitions. The tool targets these common locations to identify and extract inline types, applying recommended refactorings to reduce redundancy.

Verify TypeScript refactoring changes by running yarn typecheck, yarn lint, yarn prettier, and yarn build. These commands enforce code quality and compilation checks to ensure the extracted and unified types do not break the existing codebase.
