title: Is there a way to use Gemfury in conjunction with packages in Github Packages?
body: <p>I believe the answer is no, but hoping for something different. =)</p>
  <p>I'm experimenting with Gemfury as a provider, and as such moving some private packages into it, but not ready to move all of them. Some of them need to reside in Github Packages for a while longer.</p>
  <p>In the mean time, consumers need to be able to install from the regular npm registry, Github Packages and now Gemfury.</p>
  <ul>
  <li>public npm + Github Packages -&gt; works</li>
  <li>public npm + Gemfury -&gt; works</li>
  <li>public npm + Github Packages + Gemfury -&gt; haven't found a way to get this to work</li>
  </ul>
  <p>Is this possible? Are there docs or guides on how to accomplish this ultra-blended-index? From <a href="https://gemfury.com/help/npm-registry/" rel="nofollow noreferrer">https://gemfury.com/help/npm-registry/</a> I can't derive how to set up the version that combines all 3.</p>
  <p>The closest I got to this to working was with the following <code>.npmrc</code></p>
  <pre><code>@ourscope:registry=&lt;&lt;github_packages_url&gt;&gt;
  registry=&lt;&lt;gemfury_proxy_url&gt;&gt;
  //n&lt;&lt;gemfury_proxy_url&gt;&gt;/:_authToken=${NPM_GEMFURY_AUTH_TOKEN}
  engine-strict=true
  </code></pre>
  <p>The above works locally, but doesn't seem to work on CI though
  Since I couldn't find any documentation to support it, I'm not even sure if it should be working locally or if it's just a happy accident of sorts.</p>
  <p>Any insights on whether this is possible and how to adopt it would be appreciated!</p>
