Zustand State Management Patterns FAQs

Question 1

When should I use Zustand instead of useState?

Accepted Answer

Use Zustand for shared UI state needed by two or more components across your application tree. Use useState strictly for state that is truly local to a single component and never needs to be shared.

Question 2

Can I use Zustand for API and server data?

Accepted Answer

No. This skill follows the philosophy that server/API data should be handled by dedicated data fetching solutions (like TanStack Query) to manage caching and synchronization. Zustand should be used for shared client-side UI state.

Question 3

What are the specific requirements for Zustand v5 in this skill?

Accepted Answer

Zustand v5 requires selectors to return stable references to prevent infinite loops. It also moves from the old equality-function argument to the useShallow hook and changes how the persist middleware handles initial state.

Question 4

Why does this skill discourage using Context for state management?

Accepted Answer

Context API is designed for dependency injection, not frequent state updates. Using it for state management causes every consumer component to re-render whenever any value in the provider changes, which leads to performance issues.
