How can I implement authentication with React Query?

You can implement authentication in React Query by using the useMutation hook for login and useQuery for fetching user data.

Can you show me a code example for the login mutation?

Sure! Here's a simple example:

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

Make sure to replace loginUser with your actual login function.

What about handling errors during login?

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

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

How do I protect routes based on authentication status?

You can use a context provider to manage authentication state and wrap your routes with a check to redirect unauthenticated users.
