How do I authenticate users in a React application?

To authenticate users in a React app, you can use libraries like Firebase, Auth0, or implement your own authentication with JWT.

What is JWT and how does it work for authentication?

JWT stands for JSON Web Token. It's a compact, URL-safe means of representing claims to be transferred between two parties. It allows you to verify the token's authenticity and the user's identity.

Can you show me a simple example of using JWT in React?

Sure! First, you need to install a library like jsonwebtoken. Then, you can create a login function that generates a token and stores it in local storage.

What about protecting routes in my React app?

You can protect routes by using a higher-order component or a custom hook that checks if the user is authenticated before rendering the component.
