How can I securely handle sensitive data in a React application?

To securely handle sensitive data in a React app, you should avoid storing sensitive information in the client-side state. Instead, use environment variables for API keys and ensure that sensitive data is processed on the server.

What about using local storage for sensitive data?

It's not recommended to use local storage for sensitive data, as it can be easily accessed by malicious scripts. Instead, consider using secure cookies or session storage with proper security measures.

How can I protect my API keys?

You can protect your API keys by storing them in environment variables and using a backend server to make API calls. This way, the keys are not exposed to the client.

Are there any libraries that can help with this?

Yes, libraries like Axios for making HTTP requests and dotenv for managing environment variables can help you securely handle sensitive data in your React application.
