Any state changes are stored in the Redux store, and any state changes come from dispatching actions to Redux reducers. In traditional redux, you may write actions and reducer functions separately just as shown below: ActionsĬonst counterReducer = (state = intialState, action) => from "./slices/counterSlice" Redux is a library that is used to manage the state of the application. Here’s what the routing structure currently looks like: // App.Install the required packages first in order to use Redux Toolkit and React-redux in your React application. The frontend folder also includes the various user interfaces seen in the demo, such as Home, Login, Register, and Profile screens with respective routes /, /login, /register, and /user-profile. React Redux has its type definitions in a separate types/react-redux typedefs package on NPM. RTK is already written in TypeScript, and its API is designed to provide a good experience for TypeScript usage. The repository includes a starter-files branch that contains the necessary files to bootstrap this application. Redux Toolkit (RTK) is the standard approach for writing modern Redux logic. Now, let’s start authenticating! Cloning starter files from GitHub

In this article, you’ll learn how to use Redux Toolkit (RTK) and RTK Query to create a frontend authentication workflow in React. Regardless of how such services handle authentication and authorization on their end, the implementation process typically involves calling some API endpoints and receiving a private token - usually a JSON Web Token, or JWT - to be used in your frontend infrastructure. Because of this feature’s importance, we’ve seen more companies provide authentication solutions to ease the process - Firebase, Auth0, and NextAuth.js, to name a few.
