Query endpoints can now accept a retr圜ondition callback as an alternative to maxRetries. The refetch() methods now return a promise that can be awaited. ![]() That should keep the call stack shorter in the cases where API actions really are being processed. Actions now only receive extra processing if they're actually related to the API slice itself, and that processing is done via a loop over handling logic at the end of the middleware unwind phase, rather than nesting function calls through multiple sub-middleware. We've rewritten the internals of the middleware to be more efficient. We've also had some reports that users with multiple API slices were occasionally seeing "Maximum call stack size exceeded" errors. This added multiple function calls to each dispatch's stack trace, and even if there isn't a noticeable perf hit, it wasn't efficient. While this worked well for encapsulating responsibilities, it also meant that every dispatched Redux action had to go through 7 additional middleware. That middleware itself has been made up of 7 individual middleware internally composed into the final middleware, with each individual middleware responsible for a different task like managing polling or cache lifetimes. RTKQ automatically generates a Redux middleware for each "API slice" / createApi call. RTKQ Middleware Performance Optimizations As with the other util methods, this is a thunk that should be dispatched, and you should pass in the exact cache key arg and complete data value you want to insert: dispatch( ![]() This release adds a new API that allows creating a cache entry + its data programmatically. RTKQ already has an updateQueryData util to synchronously modify the contents of an existing cache entry, but there was no way to create a new cache entry and its metadata programmatically. Still no specific ETA for release, but we hope for Soon (TM) :) The remaining work is filling out docs and preparing the "object reducer" codemods for release alongside 1.9. Hope you found this informative and if you would like to learn more about Redux Toolkit, check out the official documentation.This feature preview release adds new options and improves behavior for RTK Query.Īs of this alpha, RTK 1.9 is feature-complete and we do not expect additional meaningful changes. Using it in React Native is very easy and should definitely be considered over regular Redux workflow. Redux Toolkit provides many advantages when building state management solution, especially when combined with asynchronous requests and normalized data. If you need to see full example code, you can find it on our repository. import = useSelector((state: RootState) => ers) Ĭonst users = useSelector(selectAllUsers) Redux Toolkit provides a convenience function createSlice that helps managing state slice. Let's start with creating a simple state slice that holds a message state. Next, let's install all the necessary dependencies and typings: $ npm i react-redux npm i -save-dev state setup Create state slice To get started, I'm going to create a new React Native project with typescript template: $ npx react-native init ReduxToolkitExample -template react-native-template-typescript Using Redux Toolkit in React Native is straightforward, so let's setup a simple application and see it in action! You can follow along the article or if you prefer you can also find all of the example code on our GitHub repo. It also includes many convenience features that help supercharge your state management. Redux Toolkit is an official package from the Redux Team that helps configuring Redux store and reduces boilerplate.
