Todo List Web App With React And Vite – PART 6: Redux Setup

In this article, we will be setting up Redux in our Todo List web app. Redux is a predictable state container for JavaScript apps and helps in managing the state of the application in a predictable manner. It is commonly used with React applications to manage the application state.

Installing Redux

Before we can start using Redux in our application, we need to install the necessary packages. We can do this by running the following command in the terminal:

npm install @reduxjs/toolkit react-redux
  

Setting Up the Redux Store

Once we have the required packages installed, we can set up the Redux store in our application. We will create a new file for the store configuration. Let’s create a file named store.js and add the following code:

    import { configureStore } from '@reduxjs/toolkit';
    import todosReducer from './features/todos/todosSlice';
    
    export const store = configureStore({
      reducer: {
        todos: todosReducer,
      },
    });
  

Connecting the Redux Store to the Application

Now that we have set up the Redux store, we need to connect it to our application. We can do this by wrapping the root component of our application with the Provider component from the react-redux package. Let’s update our index.js file to include the Provider component:

    import React from 'react';
    import ReactDOM from 'react-dom';
    import { Provider } from 'react-redux';
    import { store } from './store';
    import App from './App';
    
    ReactDOM.render(
      <Provider store={store}>
        <App />
      </Provider>,
      document.querySelector('#root')
    );
  

With these steps, we have successfully set up Redux in our Todo List web app. We can now use the Redux store to manage the state of our application and dispatch actions to update the state.

Conclusion

Redux is a powerful tool for managing the state of React applications, and it can greatly simplify the process of managing application state. In this article, we have learned how to set up Redux in our Todo List web app using the @reduxjs/toolkit package. We have also seen how to connect the Redux store to our application using the Provider component from the react-redux package. With Redux in place, we can now manage the state of our application in a predictable and efficient manner.
