What is CSRF in React and how can I prevent it?

CSRF stands for Cross-Site Request Forgery. It's an attack that tricks the user into submitting a request they didn't intend to. In React, you can prevent CSRF by using anti-CSRF tokens, which are unique tokens generated for each session.

How do I implement CSRF tokens in my React app?

You can implement CSRF tokens by generating a token on the server-side and sending it to the client. Then, include this token in the headers of your requests. Libraries like Axios allow you to set default headers easily.

Are there any libraries that can help with CSRF protection?

Yes, libraries like csurf for Express.js can help manage CSRF tokens. For React, you can use Axios or Fetch API to include the token in your requests.

What are some common mistakes to avoid when implementing CSRF protection?

Common mistakes include not validating the token on the server, using the same token for multiple sessions, and forgetting to include the token in AJAX requests.
