Quick Reference
Custom Hooks: Extract reusable stateful logic. Naming: use* prefix. Return tuple [value, setter] or object { data, error, loading }. Compose hooks (useDebounce + useAsync). Test with @testing-library/react renderHook. Keep hooks focused on single responsibility.
Use When
- Sharing stateful logic between components
- Abstracting complex state management
- Wrapping browser APIs (localStorage, fetch)
- Creating reusable data fetching logic
Skip When
- Simple one-off logic
- No state or effects involved
- Component-specific logic that won't be reused
