![]() That's it, now you can add redux-toolkit to your project and do more complex state management. But for simplicity we use demo auth using redux state. In real life you would want to implement a full authentication server and validation. It is equally easy to drop Redux Toolkit into an existing React project. You will be logged out and login form will be shown again. Click on Login button and you'll be logged in and you will see your profile page with your name Replace createStore with configureStore from the toolkit and pass the reducer to the Redux function configureStore, which then returns a store object. npm i reduxjs/toolkit npm uninstall redux redux-devtools-extension redux-thunk. This should start your development server on port 3000 by default. Install the toolkit and remove other packages that come with it, by default. Go to your project root directory and run: You can find sample code used in this tutorial on Github at /htthecool/react-redux-toolkit-tutorial ![]() Import from'./store/authSlice' Ĭonst auth= useSelector((state) => th) If you image a filing rack as your redux-store, then slices are the individual racks, each slice holding an organized unit of state. Slices are at the centre of redux-toolkit. Now that you understand the concept, let's dive into the code that you need to create redux store and change global state using reducer functions. See the diagram below for an overview of redux-toolkit This way your reducers are contained within the slice and it's easier to understand and manage global state. Redux toolkit helps you organize your global state by slicing your global state into smaller slices. Don't worry, we'll see these later in this tutorial Concept Npm install 'react-redux' is provided by redux that enables us to use bindings that connect toolkit with our react is a toolkit by redux that provides a few handy features such as slices and direct state manipulation in reducers. To use redux-toolkit you need to install these dependencies: Npm install -g npx Install redux-toolkit dependencies If you don't have npx installed then install it first: If you don't have existing react application then you can create a new one: There are far too many blogs and articles about Redux and react-redux, so I would leave the details and jump into how to install redux-toolkit in your react application. Redux can be used in any JavaScript application. If you want an easier global state in your React application, then you can check out React Context There are various advantages of using global state. In short, it allows you to have global state in your application. Here's a codesandbox for you to play around with.Redux is a state container for your application. This is just an architecture thing of reduxĪt the click of a button, we dispatch an action that calls the reducer function to update the slice of our store.Ī diagram to represent how it all comes together ![]() Now this action will call our reducer function and perform the necessary actions which we specified in the reducers of our cartSlice Remember how we exported addItem in our cartSlice? Don't scroll up, look here Why do we need a useDispatch? it's used to dispatch an action that calls the reducer function. Next, import useDispatch from react-redux import from "react-redux" įirst import the reducer function you have to use. It acts as a central place to access all our data. We will be taking a shopping cart example for the working of the app. What is this react-redux library? this helps us to communicate between react and redux, as the name suggests. So this blog will first explain the sequence in which you are supposed to follow, then I'll explain the working of it.Ī few things to note, Redux toolkit is a newer version of the actual Redux library, this blog will only consist of the newer version as it is simpler. Sometimes, the most effective way of understanding something comes from doing it first and then understanding it by observing how everything came together. I have taken some amazing explanations from there and decided to make a mini documentation of it here. As a beginner, I tried to understand redux on my own through docs and blogs.Įventually, I learned it from Akshay Saini's boot camp called Namaste React and I have been very grateful for it.
