How do I implement JWT authentication in my React app?

To implement JWT authentication in your React app, you'll need to follow these steps: 1. Set up a backend server to handle authentication. 2. Create a login form in your React app. 3. Send a request to the server with user credentials. 4. On successful login, the server will return a JWT. 5. Store the JWT in local storage or a cookie. 6. Use the JWT for subsequent requests to protected routes.

What libraries do I need for this?

You can use libraries like Axios for making HTTP requests, and you might want to use a library like jsonwebtoken on the server side to create and verify JWTs.

How do I protect my routes in React?

To protect your routes, you can create a higher-order component (HOC) or use React Router's PrivateRoute component. This will check if the user is authenticated before allowing access to certain routes.

Can I refresh the JWT automatically?

Yes, you can implement a refresh token mechanism. When the JWT expires, you can use a refresh token to obtain a new JWT without requiring the user to log in again.
