How to Manage User Sessions and Tokens in Redux Applications?

This project is designed to provide a basic user authentication system entirely on the client side using React and Redux, allowing users to login, register, and logout. Authentication actions and state management are managed locally, with user data stored in the browser's local storage.

Approach

• Project Setup : Created a React application is using create-react-app and Install Redux and React-Redux to manage the application's state
• State Management: Initial state includes token and user data retrieved from local storage.
• Reducer: Make LOGIN_SUCCESS to validates credentials and sets token. REGISTER_SUCCESS adds new user and LOGOUT clears token from local storage.
• Components: Make Login, Register, and Logout components and handle user authentication and dispatch actions.
• Conditional Rendering : Authenticated users see the Home component and Logout button. Unauthenticated users see the Login and Register components.

Step to Create Application

Step 1: Create a React Application named 'auth-app' and navigate to it using this command.

npx create-react-app auth-app
cd auth-app

Step 2: Install required packages and dependencies.

npm install react-redux redux
