SWR VS redux-toolkit

For server-state (data fetched from an API), tools like React Query or SWR shine. They handle caching, refetching, and error states without needing to push API responses into Redux.

Following is overview picked from SWR site.

If you need more robust features—like caching, re-fetching, or pagination—check out libraries like React Query or SWR. Many of these tools also offer optional Suspense modes, so you can keep your data-fetching code clean while benefiting from powerful caching and refetching mechanisms.

Client-Side Data Fetching with useQuery can be used for interactive components that need to fetch data on the client-side, with initial state hydrated from server-side fetched data. For fetching data that changes frequently or for adding client-side interactivity it is useful the useSWR strategy. It’s a React hook for client-side data fetching with caching and revalidation. It allows fetching data on the client side, usually after the initial page load. Nevertheless, it does not fetch data at build time or on the server for SSR, but it can revalidate and fetch new data when required.

swr

We can do this with React-Query, SWR, Redux Toolkit Query and many others.

This is a common approach in JS land, and there are plenty of libraries that help abstract the logic and make sure the state is consistent, like swr or TanStack Query.

Redux Toolkit Documentation

Redux Toolkit offers a robust and predictable framework that scales well with large applications.

8. Redux & Redux Toolkit – State Management Simplified 🧠

Redux is a predictable state management tool for JavaScript apps. A state is something that keeps the app running for example when you are asked to select gender in a website, the state is either male or female.

I said the wrong shape, because I think that, if redux-toolkit was the version people used a lot in the past, their views on redux would be different today. Being more positive, than it is.

So you can imagine how much more we'd need to write to introduce reducers and actions in a real-world application. This is where Redux ToolKit comes in very handy.

Redux is rather overkill in today's front end ecosystem if you're building an MVP, and as of late more have been using redux-toolkit or useReducer to update slices of state.4
