`require('https')` standard library to do `HTTP` requests	`https.request(` create new HTTP request
`method: 'POST'` ask Nodejs to make `POST` request	`{a: 1, name: 'Joe'}` sample JSON data to post
`'Content-Length': data.length` we need to send posted content length to the server	`resp.on('data'` handle response in chunks
`(chunk) => { data += chunk; }` collect all response chunks into single string	`resp.on('end'` fired when response ended
`console.log(data);` outputs full response from given URL	`req.write(data)` write `data` to given request (post `data` contents)

Usage example

const https = require('https');

let data = JSON.stringify({a: 1, name: 'Joe'});

let req = https.request({
  hostname: 'echoof.me',
  port: 443,
  path: '/',
  method: 'POST',
  headers: {
    'Content-Length': data.length,
    'Content-type': 'application/json'
  }
}, (resp) => {
  let data = '';
  resp.on('data', (chunk) => { data += chunk; });

  resp.on('end', () => {
    console.log(data);
  });
});

req.write(data);
