How do I implement JWT authentication in my React app?

To implement JWT authentication in your React app, you need to follow these steps: 1. Set up a backend server to issue JWTs. 2. Create a login form in your React app. 3. Send a request to the backend with user credentials. 4. Store the received JWT in local storage or cookies. 5. Use the JWT for authenticated requests.

What libraries do I need for this?

You can use libraries like Axios for making HTTP requests and jsonwebtoken for handling JWTs on the server side.

How do I protect my routes in React?

You can create a higher-order component (HOC) or use React Router's PrivateRoute to protect your routes by checking if the user is authenticated.

What should I do if the token expires?

You should implement a refresh token mechanism to obtain a new token without requiring the user to log in again.
