managing-state

To manage frontend state efficiently, use React Context strictly for infrequently changing global static values like themes or internationalization settings. For dynamic client state, use Zustand with selectors to isolate updates and prevent unnecessary re-renders across your application.

The best way to structure frontend state is by using a state decision tree: implement TanStack Query for server state like API data fetching and mutations, and use Zustand for isolated client state like shopping carts. This ensures typed, performant stores across your application.

You need TanStack Query for server state when fetching, caching, or mutating API data, especially when implementing optimistic updates. Local useState should only be used for simple, component-level UI state rather than managing remote server data synchronization.

Yes, this state management strategy handles both scenarios by separating concerns. You can use TanStack Query to fetch and cache user authentication data from an API, while simultaneously maintaining a typed Zustand store for shopping cart client state.

To set up a Zustand store for client state management, define your store with typed state values and implement selectors. This approach isolates state updates, allowing components to subscribe only to specific state slices and minimizing unnecessary re-renders during updates.

You should use a state decision tree for frontend state organization because it guides whether to use Zustand, TanStack Query, React Context, or local state for each specific data type. This ensures performance and maintainability by applying the right tool to the right problem.
