Using speedtest.net api with React Native

Question

I'm creating a Android React Native application and trying to use the speedtest.net api to get the upload and download speed for a mobile device. However, when I try to integrate the library in React Native, I'm getting the following error when I try to do const test = speedTest({maxTime: 5000, serverId : "7334"});

Actually before this, I had trouble trying to even add the speedtest npm module to React Native and got a 500 error:

Error: Unable to resolve module url from C:\Users\user\Documents\mobileapp\node_modules\speedtest-net\index.js: Module url does not exist in the Haste module map

The line of code I was putting into my React Native app: var speedTest = require('speedtest-net');

I managed to find this article to fix the issue, but this is where I get the first error now... How can I properly use a npm module in my React Native application without getting all of these errors? Is there possibly a better way to integrate the speedtest.net npm module into my React Native app? Here is my code:

import React, {Component} from 'react';
import {Platform, StyleSheet, Text, View} from 'react-native';

const instructions = Platform.select({
  ios: 'Press Cmd+R to reload,\n' + 'Cmd+D or shake for dev menu',
  android:
    'Double tap R on your keyboard to reload,\n' +
    'Shake or press menu button for dev menu',
});

//using the node module
const speedTest = require('speedtest-net');

//using the instructions from the article
const speedTest = require('./speedtest');
const test = speedTest({maxTime: 5000});

type Props = {};
export default class App extends Component<Props> {
  constructor()  {
    super();
  }

  componentWillMount() {
    test.on('downloadspeed', speed => {
       console.log('Download speed:', speed.toFixed(2));
   });

    test.on('uploadspeed', speed => {
       console.log('Upload speed:',(speed * 125).toFixed(2),'KB/s');
    })
  }

  render() {
    return (
      <View style={styles.container}>
        <Text style={styles.welcome}>Welcome to React Native!</Text>
        <Text style={styles.instructions}>To get started, edit App.js</Text>
        <Text style={styles.instructions}>{instructions}</Text>
      </View>
    );
  }
}

Also I tried to test out the API separately and it worked perfectly fine. It's just that when I try to implement the API with React Native, I'm getting all of these issues. Here is how my code for the other js file looks like:

var speedTest = require('speedtest-net');
var test = speedTest({maxTime: 5000, serverId : "7334"});
var http = require('http');

// test.on('data', data => {
//   console.log(data);
// });

// test.on('error', err => {
//   console.error(err);
// });

test.on('downloadspeed', speed => {
  console.log('Download speed:', speed.toFixed(2));
});

test.on('uploadspeed', speed => {
  console.log('Upload speed:',(speed * 125).toFixed(2),'KB/s');
})

http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/html'});
    res.end('Hello World!');
}).listen(8080);
