How can I implement authentication with React Query?

You can implement authentication in React Query by using the useMutation hook to handle login and registration.

Can you show me an example of using useMutation for login?

Sure! Here's a basic example:

const loginMutation = useMutation(loginUser, {
  onSuccess: (data) => {
    // Handle successful login, e.g., store token
  },
});

You would call loginMutation.mutate(credentials) to trigger the login.

What about handling errors during authentication?

You can handle errors by using the onError callback in the useMutation options. For example:

const loginMutation = useMutation(loginUser, {
  onError: (error) => {
    // Handle error, e.g., show a message
  },
});
