Problem Statement
What are the essential best practices for using Redux in production applications?
Explanation
Essential best practices include using Redux Toolkit as the standard approach to reduce boilerplate and follow conventions, keeping state normalized and minimal with derived data in selectors, organizing code by feature rather than type for better maintainability, and using TypeScript for type safety across actions, state, and selectors. Always use memoized selectors for derived data to optimize performance, leverage RTK Query for data fetching to handle caching automatically, write comprehensive tests for reducers and selectors as pure functions, and use Redux DevTools effectively for debugging. Follow the principle of putting only truly global state in Redux while keeping local state in components, and ensure all state is serializable for proper debugging and persistence.
