When it comes to managing state in a React app, developers often face a dilemma: Redux or TanStack Query? Both libraries have their strengths and weaknesses.

Redux is perfect for handling global state, such as user authentication, shopping cart, and theme. It provides a centralized store where data can be accessed by any component that needs it.

TanStack Query, on the other hand, excels at managing server state (data fetched from an API). It handles asynchronous data, caching, and refetching to ensure the UI shows the latest information. This makes it ideal for tasks like fetching and syncing data from APIs or databases.

In reality, both libraries can coexist in a project. Use Redux for local/global app state and TanStack Query for server data that needs to be fetched and kept up-to-date. By choosing the right tool for the job, developers can create more efficient, organized, and maintainable apps.
