Redux Toolkit is a powerful library that simplifies the usage of Redux in React applications. It provides a set of tools and conventions that eliminate many common pain points when working with Redux.
Getting Started
To get started with Redux Toolkit, first, make sure you have a React application set up. If not, you can create one using create-react-app. Then, follow these steps:
- Install Redux Toolkit and its dependencies by running the following command:
npm install @reduxjs/toolkit react-redux
- 
    Create a new file called store.jsin your project’s directory. This file will contain the store configuration and all your Redux logic.
- 
    Open store.jsand import the necessary dependencies:
import { configureStore } from "@reduxjs/toolkit";
- Define your initial state and create a reducer function using the createSlicefunction provided by Redux Toolkit:
const initialState = {
  counter: 0,
};
const counterSlice = createSlice({
  name: "counter",
  initialState,
  reducers: {
    increment(state) {
      state.counter++;
    },
    decrement(state) {
      state.counter--;
    },
  },
});
- Create the Redux store by calling the configureStorefunction and passing in your reducer:
const store = configureStore({
  reducer: counterSlice.reducer,
});
- Wrap your app component with the Providercomponent fromreact-reduxand pass it thestoreas a prop:
import { Provider } from "react-redux";
ReactDOM.render(
  <Provider store={store}>
    <App />
  </Provider>,
  document.getElementById("root")
);
- Now you can access the Redux store in your components. To use the store, import the useDispatchanduseSelectorhooks provided by thereact-reduxlibrary:
import { useDispatch, useSelector } from "react-redux";
- To dispatch actions, use the useDispatchhook and call your action creator functions defined in your slice:
const dispatch = useDispatch();
const handleIncrement = () => {
  dispatch(counterSlice.actions.increment());
};
const handleDecrement = () => {
  dispatch(counterSlice.actions.decrement());
};
- To access the state from the store, use the useSelectorhook and pass in the appropriate selector function:
const counter = useSelector((state) => state.counter);
Conclusion
Redux Toolkit simplifies the process of using Redux with React by providing a set of opinionated tools and conventions. It helps eliminate boilerplate code and makes state management more straightforward and efficient. By following the steps above, you can easily integrate Redux Toolkit into your React application and leverage its benefits.
