Basically, you can write a function which will return a Promise and then you can use async/await with that function. Please see below:

const https = require('https')  const data = JSON.stringify({   todo: 'Buy the milk' });  const options = {   hostname: 'flaviocopes.com',   port: 443,   path: '/todos',   method: 'POST',   headers: {     'Content-Type': 'application/json',     'Content-Length': data.length   }, };  async function doSomethingUseful() {   // return the response   return await doRequest(options, data); }   /**  * Do a request with options provided.  *  * @param {Object} options  * @param {Object} data  * @return {Promise} a promise of request  */ function doRequest(options, data) {   return new Promise((resolve, reject) => {     const req = https.request(options, (res) => {       res.setEncoding('utf8');       let responseBody = '';        res.on('data', (chunk) => {         responseBody += chunk;       });        res.on('end', () => {         resolve(JSON.parse(responseBody));       });     });      req.on('error', (err) => {       reject(err);     });      req.write(data)     req.end();   }); }
