At this point you can either create a Redux Slice, or use Context.

So now that RTK has a Server State solution the deciding factor comes down to how you want to manage the remaining Global State in your app. This can be incredibly powerful for any any tool that integrates with Redux, like Sentry. This allows every interaction to be visible by all Redux Reducers, and even the Redux DevTools. Every interaction with RTKQ dispatches a Redux Action. One big benefit of using RTKQ is that it integrates with your Redux Store. Similar to SWR & React Query, RTK Query is a data fetching and caching tool that manages Server State. In June 2021 Redux Toolkit added a very powerful tool that makes Redux a more viable solution: RTK Query. At this moment in time I was a strong advocate for avoiding Redux, in favor of a Server State tool + Context. The remaining Global State, if any, could easily be managed with the Context. Server State aims to keep the single-source-of-truth on the server, likely persisted in a database, and remove the need for maintaining and synchronizing server derived state with Global State.īecause of the little Global State that remains when abstracting Server State to a query tool, there is little reason to use Redux. SWR created by Vercel, and React Query created by Tanner Linsley, both solve the same problem: fetching, caching, synchronizing, and updating Server State. In 2019 SWR & React Query were introduced to the React community. That is in large part because around the time RTK was released, so were the Server State tools. import = themeSlice.actions export default themeSlice.reducer īut even with RTK, I still wasn’t sold. The 2 big features that make RTK worthwhile in my eyes are createSlice, and the opinionated Style Guide.Ī slice is where you define the state of a feature which ultimately gets passed to combineReducers when configuring your store. Mark Erikson’s vision for RTK aimed to solve the aforementioned problems, and ultimately succeeded. It is intended to be the standard way to write Redux logic, and we strongly recommend that you use it.”- Redux Team “Redux Toolkit is our official, opinionated, batteries-included toolset for efficient Redux development. In October of 2019 Redux Toolkit 1.0 was released. Lack of a standard architecture - no 2 Redux implementations were the same few were good.Redux helps prevent prop drilling and makes managing state across many components much easier.īut classic Redux comes with many pain points including: Redux creates a Global State named a Store, and allows you to connect Components to the Store to gain access to the Global State. Redux was created in 2015 by Dan Abramov and Andrew Clark as a solution for managing and providing state across an entire React application. (and for the sake of this conversation - automatically managed in client cache, using a tool like React Query.) Server State: Refers to state persisted on a server.Global State: Refers to state persisted within a global store that all components have access to.Local State: Refers to state persisted within a React Component.We will be discussing the following types of state:

State is persisted information that determines how an app will be rendered. At the beginning of the year if you told me I’d be publishing a recommendation to use Redux I would have laughed in your face.
