title: How can I replicate the functionality of a wget with node.js?
body: <p>Is it possible to essentially run a <code>wget</code> from within a node.js app? I'd like to have a script that crawls a site, and downloads a specific file, but the <code>href</code> of the link that goes the file changes fairly often. So, I figured the easiest way to go about doing it would be to find the <code>href</code> of the link, then just perform a wget on it.</p>
  
  <p>Thanks!</p>
