Part 42 React Tutorial | Login Integration with Backend | Authentication | JWT token | Interceptors

Login Integration with Backend:- Integrating login functionality with a backend in a React application typically involves sending user credentials to the backend server, verifying them, and returning a response to the client with a JWT (JSON Web Token) or session ID to indicate successful authentication. 1. Create a login form component with input fields for email/username and password. 2. In the handleSubmit function of the login form component, use the fetch API to send a POST request to the backend server with the user's credentials. 3. On the backend server, verify the user's credentials and generate a JWT or session ID to indicate successful authentication. 4. On the client side, store the JWT in sessionStorage and use it to authenticate subsequent requests to protected endpoints
