title: NodeJS: ENAMETOOLONG, how long is too long?
body: <p>The <a href="https://nodejs.org/api/os.html" rel="noreferrer">https://nodejs.org/api/os.html</a> says:</p>
  
  <blockquote>
    <p>ENAMETOOLONG  Indicates that the filename is too long.</p>
  </blockquote>
  
  <p>but, how long is too long, if I am to prevent it from happening myself beforehand? </p>
