title: How can I uninstall npm modules in Node.js?
body: <p>As commonly known, any npm module can be installed by running a simple command: <code>npm install &lt;module_name&gt;</code>.</p>
  <p>I have installed a few modules that I do not use any more and I just want to get them off. I have a few questions regarding this:</p>
  <ul>
  <li><p>Do we have any command or process to uninstall a module from the root (something like <code>npm uninstall &lt;module_name&gt;</code>)
  or will simply removing the module files do?</p>
  </li>
  <li><p>How does it affect us if we keep the unused modules?</p>
  </li>
  </ul>
