If we go back to our products page, it's fully working, but instead of being powered by local component state, it's now powered by Redux. React Class Components Check out the PostDetail component for an example of Class Component usage. Now we can remove the unneeded useState import and the unneeded Product import. Using extraReducers This example uses a matcher from the endpoint and extraReducers in the authSlice. It's two methods instead of one, but at the end of the day, it's just a single line of code that's pretty easy to read. You can see how dispatching this into Redux isn't that much harder than setting products on the local component state. A Web Developer in Sydney Published: JReact + Redux Toolkit - Fetch Data in Async Action with createAsyncThunk Tutorial built with React 18.1.0, Redux 4.2.0 and Redux Toolkit 1.8.2 This is a quick example of how to fetch data from an API in Redux using an async action created with the Redux Toolkit's createAsyncThunk () function. We'll bring our useEffect hook back into it, but instead of calling setProducts, once the products are received, we are going to call dispatch(receivedProducts(products)). We'll then remove our useState line here. Here at the top of the Products() component, type const dispatch = useAppDispatch(). Now that we've created that reducer method, we can export an action for it by typing export const from "././app/hooks". We're essentially converting our product array into a products object. For each product we'll say state.products = product. Let's save those products into a variable called products, and let's convert them into an object by looping over them. In this case, our payload is going to be an array of Product. That type takes in as an argument the value that we want our action payload to look like. PayloadAction is a special type that we're going to import from react.js/toolkit. It's going to have the type of PayloadAction. That method is going to take state, and it's also going to take something called an action. Therefore, our data will still remain even after a browser refresh. Several barriers persist while using Redux, which the Redux js toolkit attempts to address. Jamund Ferguson: In productsSlice.ts, make sure to clear out any fake products you created in your initialState, and down here in reducers let's add a new reducer method called receivedProducts. In this tutorial, we’ve learned how to use Redux Persist in Redux Toolkit to save our data in persistent storage. When developers work on a large project employing the most popular frameworks Angular, React, or Vue, then state management library is a key factor they deal with.
