title: Is there any way to configure multiple registries in a single npmrc file
body: <p>Here is my problem. We have a private NPM registry which only works in VPN. I would like to have a fallback registry <a href="https://registry.npmjs.org" rel="noreferrer">https://registry.npmjs.org</a> so that when I am out of VPN it works seamlessly.</p>
  <p><strong>P.S.</strong> Currently I am using <a href="https://www.npmjs.com/package/npmrc" rel="noreferrer">npmrc</a> which does a good job in switching between <code>.npmrc</code> files as a workaround</p>
