Which state management stack would you suggest for this project — React Query, Redux Toolkit, RTK Query?

For a hotel booking project, the choice of state management stack depends on the nature of the data and server interaction.

• React Query is excellent for managing server state — loading, caching, updating data from the server. If the application makes many API requests (hotel lists, details, bookings), React Query simplifies working with asynchronous data and ensures data freshness.

• Redux Toolkit (RTK) is a powerful tool for managing local application state, such as user settings, filters, UI states. If the app requires complex local state logic, RTK will be useful.

• RTK Query is an extension of Redux Toolkit for working with server data, combining the advantages of Redux and React Query. If Redux is already used in the project, RTK Query allows convenient API handling, caching, and data updating.

Recommendation:

• If the project is small or medium and Redux is not used, it's better to use React Query for server state and React Context or RTK for local state.
• If Redux is already in use, then RTK Query is the optimal choice for working with APIs.

Thus, for state management in a hotel booking service, I would suggest combining React Query (or RTK Query if using Redux Toolkit) for server data and Redux Toolkit for local state.
