user registration with react query

[AbyerAli]

I am new to query environment so need some help
gimme a general idea of how user login and signup is implemented in react query

right now i am just loging in user via useMutation
code:

export const useGetBuyerData = () => {
  const loginBuyer = async ({ email, password }) => {
    const response = await axios.post("/api/users/userLogin", { email, password });
    return response.data;
  }
  return useMutation(loginBuyer);
}

const {
    mutate,
    data: loginData,
 } = useRegisterBuyer();

how is a centralized state achived here so my user data is saved and how the registration is impleted ?

same as any other mutation/query combination: invalidate the query that fetches the information of the logged-in user after login.
