Create a Redux store with configureStore.

That was a brief overview of how to set up and use Redux Toolkit with React.

The component will see the new state value from the store and re-render itself with the new data.

The counter slice reducer will see the actions and update its state.

The corresponding Redux action will be dispatched to the store.

Now, any time you click the 'Increment' and 'Decrement buttons: Import styles from './'Ĭonst count = useSelector ( ( state ) => state. However, Redux Toolkit's createSlice and createReducer APIs use Immer inside to allow us to write 'mutating' update logic that becomes correct immutable updates. Redux requires that we write all state updates immutably, by making copies of data and updating the copies. Once a slice is created, we can export the generated Redux action creators and the reducer function for the whole slice.

In that file, import the createSlice API from Redux Toolkit.Ĭreating a slice requires a string name to identify the slice, an initial state value, and one or more reducer functions to define how the state can be updated. getElementById ( 'root' ) )Īdd a new file named src/features/counter/counterSlice.js. Usage Summary Install Redux Toolkit and React Redux Īdd the Redux Toolkit and React Redux packages to your project:Ĭonst root = ReactDOM. The Redux+JS template for Create-React-App comes with this same project setup already configured. The examples are based on a typical Create-React-App folder structure where all the application code is in a src, but the patterns can be adapted to whatever project or folder setup you're using. For explanations of what Redux is, how it works, and full examples of how to use Redux Toolkit, see the Redux core docs tutorials.įor this tutorial, we assume that you're using Redux Toolkit and React Redux together, as that is the standard Redux usage pattern.

This page will focus on just how to set up a Redux application with Redux Toolkit and the main APIs you'll use. Welcome to the React Redux Quick Start tutorial! This tutorial will briefly introduce you to React Redux and teach you how to start using it correctly.
