title: How to get MIME type base64 encoded string in nodejs?
body: <p>When I convert the data to <code>base64</code>, it gives a single line of <code>base64</code> string.</p>
  
  <pre><code>image = body.toString('base64');
  </code></pre>
  
  <p>How can I get <code>base64</code> string used in MIME types which is wrapped at every 76 characters? </p>
  
  <p>Is there any default method in node to achieve that?</p>
