React Query vs Redux Toolkit: Which One Is Better?
I'm a frontend developer with one year of experience. So far, I've managed small projects with just useState, but now I'm building an app with heavy data fetching, so I think I need a state management library. I've read that React Query excels at server state management, but Redux Toolkit is still widely used. Could you recommend one in terms of learning difficulty and maintainability? Has anyone here used both?

I actually recommend Redux Toolkit. Sure, the initial setup is a bit cumbersome, but you can track state changes at a glance, and logging or debugging is easy with middleware. Using only React Query might actually make things more complicated, since you'd need another library to manage client-side state (like modals or forms). If you're in your first year, learning Redux will also help you later with legacy projects.
I had a similar concern when I was in my first year, and in the end, learning React Query first worked out well. If your main focus is API fetching, it's super convenient to handle everything with just useQuery. You can always study Redux later when client-side state gets really complex. The TanStack Query official docs are well-written now, so it should be easy to follow along.
I've used both, and personally, I'm satisfied with the React Query + Context API combination. Redux has too much boilerplate, and React Query alone handles server data cleanly. If you need client-side global state, you can just add a lightweight library like Context or Zustand. The learning curve for React Query is much lower.
I personally recommend learning Redux Toolkit first. Why? Understanding Redux's patterns (actions, reducers, middleware) allows you to design more systematically even when using React Query. While React Query is convenient, debugging can become difficult later if you don't understand the basic principles of state management. RTK Query is also part of the Redux ecosystem, making it easier to scale later on.
The biggest advantage of React Query is declarative data fetching. You can directly use isLoading, isError, and data, and just by setting staleTime, it automatically keeps the state up to date. With Redux, you need to manually dispatch actions and write reducers. If you're in your first year, starting with the more productive React Query to quickly produce results seems like a good idea.
What's the scale of your project? For small teams or solo developers, React Query is much lighter and better. But if multiple people are collaborating and you need to unify state management patterns, Redux Toolkit's structure can actually be more stable. RTK Query is also available, so server state management is possible within the Redux ecosystem as well.
I had the same concern when I was in my first year... but now that I've used both, if data fetching is your main focus, React Query is the right choice. I only felt the need for Redux later when the project grew and the state tree became complex. I recommend starting with React Query now, and later studying RTK Query or Redux if needed.
Speaking from experience using both, the React Query + lightweight global state (e.g., Zustand) combination is the current trend. Redux Toolkit definitely has a learning curve, and managing server data with Redux leads to too many actions/reducers. React Query handles caching, refetching, and loading/error states automatically, making productivity much better.
