react-query에서 useMutation은 뭐하는 애일까(feat. useQuery)

• useMutation은 API에게 POST, PUT, DELETE 시 사용

// App.tsx

const client = new QueryClient({});

return (
    <QueryClientProvider client={client}>
        <HomePage />
    <QueryClientProvider>
)

// HomePage.tsx

const { mutate } = useMutation(async (param: any) => {
  const res = await axios.post("/some-url");
  return res.data;
});

return (
  <div>
    <button
      onClick={() =>
        mutate(
          { title: "TEST" },
          {
            onSuccess: (resp) => console.log(resp),
            onError: (err) => console.log(err),
          }
        )
      }
    >
      클릭
    </button>
  </div>
);
