Redux vs useState for a Netflix Clone: Choosing State in React

Redux vs useState for a Netflix Clone: Choosing State in React

A Netflix clone has movie data, auth, search, UI modals, and more. Here is how to choose between useState, Context, and Redux for each.

Movie Data: React Query or fetch in useEffect

Movie data is server state. Use React Query or fetch it in useEffect with local state for loading and error. It does not need Redux unless other parts of the app heavily interact with it.

Auth: Context

Auth is shared across the whole app, but changes rarely. Use Context. It is built into React and sufficient for user state without Redux's overhead.

Search Query: useState

The search query is local to the search page. Keep it in useState. There is no reason to lift it to Redux or Context.

UI Modals: useState

A modal open flag is local UI state. Keep it in the component that owns the modal. Do not put UI flags in Redux; that is overuse.

Cart or Playback Queue: Redux or Context

If you have a watchlist or queue that many components read and update, that is genuinely shared state. Context works for simple cases; Redux Toolkit if it is complex and frequently updated.

GPT Search Results: useState or React Query

GPT search results are server state from an AI API. Use useState with a fetch, or React Query for caching. Keep it local to the search page unless other components need it.

The Rule

Use the simplest tool that works. useState for local, Context for shared and stable, Redux for complex and frequently-updated shared, React Query for server state. Do not default to Redux.
