title: How do I determine the most popular version of a given npm package?
body: <p>The <code>npm</code> registry provides metrics on the <a href="https://www.npmjs.com/browse/depended" rel="noreferrer">most depended packages</a>, but say you wanted to determine the most popular version of a given package - is that possible? </p>
  
  <p>As a user, say I'm thinking of upgrading to <code>react-router^4.0.0</code>, but would like to look at some adoption numbers (i.e. the number of folks running <code>^3.0.0</code> vs <code>^4.0.0</code>), is there a way to do this? Generically, say a given package has 500k downloads in the past month, I couldn't imagine they are all for <code>foobar@latest</code>, so looking at a breakdown of downloads per version would seem to be useful.</p>
  
  <p>Moreover, as a publisher, say I have some packages published to <code>npm</code> and would like to understand which versions of these packages are the most popular with my users. Does <code>npm</code> offer some type of report for this? I can't seem to find these number when I'm logged in and viewing my published items.</p>
