State Management
React Choosing a State Management Library
Most applications need four separate kinds of state — local UI state, form state, server cache and genuinely global client state — and each has a different best tool. Picking one library for all four is what makes codebases painful.

Why Choosing a State Management Library matters
The common mistake is putting fetched API data into Redux and then hand-writing caching, deduplication and invalidation that a query library already provides.
Key points to remember
- Local state: useState, or useReducer when transitions have rules.
- Form state: React Hook Form for anything beyond a few fields.
- Server state: TanStack Query, RTK Query or SWR — it is a cache, not app state.
- Global client state: Context for rarely-changing values, Zustand or Redux Toolkit for the rest.
- URL state: keep filters and pagination in the query string so links are shareable.
Common mistakes with Choosing a State Management Library
- Installing Redux on day one of a small project out of habit.
- Storing server responses in a global store and reimplementing cache invalidation.
- Keeping filter state in React when the URL would make it shareable and back-button friendly.
React Choosing a State Management Library— Interview Questions & FAQs
What state management should a beginner learn first?+
useState and useReducer, then context. Learn a server-state library such as TanStack Query next — it removes more code than Redux does. Add Redux Toolkit when you join a project that uses it or genuinely need its devtools.
