Inspired by the request package.
'use strict';
const https = require('https');
const timer = require('@szmarczak/http-timer');
const request = https.get('https://httpbin.org/anything');
const timings = timer(request);
request.on('response', response => {
response.on('data', () => {}); // Consume the data somehow
response.on('end', () => {
console.log(timings);
});
});
