如何连接“网络速度”库为“反应”？

Question

给出一个错误"URL不是构造函数“

我的代码https://codesandbox.io/s/patient-dust-do1d8?file=/src/App.js

库https://www.npmjs.com/package/network-speed

import React from "react";

const NetworkSpeed = require('network-speed');
const testNetworkSpeed = new NetworkSpeed();

async function getNetworkDownloadSpeed() {
  const baseUrl = "http://eu.httpbin.org/stream-bytes/50000000";
  const fileSizeInBytes = 50000000;
  const speed = await testNetworkSpeed.checkDownloadSpeed(
    baseUrl,
    fileSizeInBytes
  );
  console.log(speed);
}

export default function App() {
  console.log(NetworkSpeed)
  return (
    <div className="App">
      <button onClick={() => getNetworkDownloadSpeed()}>34</button>
    </div>
  );
}

你不能用那个包裹来反应。

它不适合在浏览器中使用，而是在Node.js (where you have the http and https builtin modules, for one)中使用。
