How can I implement authentication refresh with React Query?

How can I implement authentication refresh with React Query?

You can use the useQuery and useMutation hooks from React Query to manage authentication state and refresh tokens.

What if the token expires while a request is in progress?

You can intercept requests and check the token's validity. If it's expired, refresh it before proceeding with the request.

Can you show me a code example?

Sure! Here's a basic example:

const { data, error } = useQuery('user', fetchUser, {
  onError: async (error) => {
    if (error.response.status === 401) {
      await refreshToken();
      // Retry the query
      queryClient.refetchQueries('user');
    }
  }
});

What libraries do I need to use for this?

You'll need React Query and a library for handling HTTP requests, like Axios or Fetch API.
