title: How can I use fs.createReadstream with fs.promises
body: <p>I use <code>require(&quot;fs&quot;).promises</code> just to avoid to use callback function.</p>
  <p>But now, I also want to use <code>fs.createReadstream</code> to attach a file with POST request.</p>
  <p>How can I do this?
  Or what alter createReadstream in this case?
  Or should I use <code>require(&quot;fs&quot;)</code>?</p>
