How do I set up JWT authentication in my React app?

To set up JWT authentication in your React app, you'll need to follow these steps: 1. Install necessary packages like axios and jwt-decode. 2. Create a login form to collect user credentials. 3. Send a POST request to your backend API to authenticate the user and receive a JWT. 4. Store the JWT in local storage or a cookie. 5. Use the JWT to make authenticated requests to your API.

What backend technology should I use for the API?

You can use Node.js with Express, Django, or Flask for your backend API. Node.js with Express is a popular choice for its simplicity and performance.

How do I protect my routes in the React app?

To protect your routes, you can create a higher-order component (HOC) that checks if the user is authenticated by verifying the JWT. If not authenticated, redirect them to the login page.

Can I use Redux for managing authentication state?

Yes, you can use Redux to manage your authentication state. Store the JWT and user information in the Redux store and update it based on login/logout actions.
