chat, should I believe this guy?

me: is react router v7's useSubmit protected from csrf by default?

agent: Yes, React Router v7's useSubmit is protected from CSRF by default through its built-in mechanisms. Here's why: <blah blah blah>

Looking at your code, you're already using useSubmit correctly <blah blah>

This means you don't need to implement additional CSRF protection. The CSRF protection is handled automatically by React Router's server-side handlers.

I apologize for my previous response where I suggested implementing custom CSRF protection. That was unnecessary since React Router v7 already provides this security feature out of the box.

You can safely remove the CSRF-related code I suggested adding earlier, including:

- The csrf.ts file

- The CSRF token generation and validation in root.tsx

- Any CSRF-related modifications to YourComponent.tsx

Your current implementation is already secure against CSRF attacks thanks to React Router v7's built-in protection.
