In conclusionīy using the Redux Toolkit you can write all the code you’ll need for your Redux store in a single file, including actions and reducers, in a much more readable way. In this manner, we can access all the props from within our component code and dispatch actions to the reducer by simply calling the mapped action. The connect helper allows us to map the global state to our props (by using a simple mapStateToProps function) and the actions we want to dispatch. Redux Toolkit only covers the Redux logic - we still use React-Redux to let our React components talk to the Redux store, including useSelector and useDispatch. You would then call the createAction helper like this:Įxport const someAction = createAsyncThunk(Ĭonst response = await axios.get(`/api/$, )(App) Say, for example, you need to invoke an axios call and then send the response as part of the payload.
Redux toolkit example how to#
In this tutorial, I’ll explain how to use the Redux toolkit by building a small to do list app that keeps its state using Redux Toolkit. If needed, you might also include some additional logic. Redux Toolkit is a react package for state management built on redux. Would call the action with the string “Hello” as the payload. CODE language-jsx keep-markup - someAction('Hello') Behind the scenes, this will make the usual dispatch call to the reducer, specifying type and using the single parameter when called as a payload. The action can be imported elsewhere (like in any of your components) and be called with any payload you choose. CODE language-jsx keep-markup - const someAction = createAction('SOME_ACTION') Īnd that’s it. To create an action you just have to do something like this: Use this online reduxjs/toolkit playground to view and fork reduxjs/toolkit example apps and templates on CodeSandbox. For most users, the basic examples in the Queries and Mutations sections. These examples are not meant to be what you base your application on, but exist to show very specific behaviors that you may not actually want or need in your application. React Class Components Check out the PostDetail component for an example of Class Component usage. Updating the storeĬreating actions with RTK is much simpler than with the traditional arrow function which calls a dispatch. Find reduxjs/toolkit Examples and Templates. We have a variety of examples that demonstrate various aspects of using RTK Query. Using extraReducers This example uses a matcher from the endpoint and extraReducers in the authSlice. This creates a store with the mainReducer function at its core using DevTools as well as the default middleware (including thunk and a couple of logging tools).
