title: Are `yarn link` and `npm link` interoperable?
body: <p>I know there are subtle differences between <code>yarn</code> and <code>npm</code>. Now I have a library managed with yarn and an app managed with npm.</p>
  <p><em>Should</em> it work without issues, if I create a linked pkg in my lib directory via yarn and apply it via npm in my other directory? Or should I expect issues with this setup? If yes, which issues might pop up and how could I avoid them (<em>except</em> converting both projects to the same manager)</p>
  <pre><code>~/the-lib$ yarn link 
  ~/app$ npm link @the/lib
  </code></pre>
