reactjs - React useQuery 导致数据前后多次重新渲染

Question

我有一个调用 API 的简单应用程序。我正在使用 react-query 进行提取并缓存数据。但是，即使该函数被包装在 中React.memo，也会useQuery无缘无故地导致多次重新渲染。它应该是 2 个渲染而不是 8 个。

import React, { memo } from "react";
import logo from "./logo.svg";
import "./App.css";
import { useQuery } from "react-query";
import Axios from "axios";

const fetchTodoList = async (key, id) => {
  const { data } = await Axios.get(
    `https://jsonplaceholder.typicode.com/posts/`
  );
  return data;
};

function App() {
  const { isLoading, isError, data, error } = useQuery("todos", fetchTodoList);
  console.log(isLoading, data);
  if (isLoading) {
    return <span>Loading...</span>;
  }

  if (isError) {
    return <span>Error: {error.message}</span>;
  }

  // also status === 'success', but "else" logic works, too
  return (
    <ul>
      {data.map((todo) => (
        <li key={todo.id}>{todo.title}</li>
      ))}
    </ul>
  );
}

export default memo(App);
