title: Create image file in nodeJs from blob
body: <p>I am receiving <strong><code>BLOB</code></strong> data on nodeJs server which is converted from PNG image.</p>
  
  <p>I need to create again png image on nodeJs server to be able to show it on pdf document.</p>
  
  <p>I had tried to use FileSaver on nodeJs but it is not working.
  FileSaver works well on reactJs app.</p>
  
  <p>How can I save a new file to the local directory on the server?</p>
  
  <blockquote>
    <p>There is a lot question pointing on problems with creating an image file
    form blob but I was unable to use base64encode, so other questions were
    not helpful.</p>
