util.promisify.custom and http.get example

promisify-http.js

const http = require('http');
const {promisify} = require('util');

http.get[promisify.custom] = function getAsync(options) {
  return new Promise((resolve, reject) => {
    http.get(options, (response) => {
      response.end = new Promise((resolve) => response.on('end', resolve));
      resolve(response);
    }).on('error', reject);
  });
};

const get = promisify(http.get);

(async () => {
  try {
    const response = await get('http://krnl.de/');
    let body = '';
    response.on('data', (chunk) => body += chunk);
    await response.end;
    console.log(body);
  } catch(e) {
    // statements
    console.log(e);
  }
})();

Nice snippet! One suggestion.

From:

response.on('data', (chunk) => body += chunk);
await response.end;

To:

for await (const chunk of response) {
  body += chunk
}

awesome!!! (╹ڡ╹ )
