title: How to import NPM package in JSFiddle?
body: <p>I would like to use <a href="https://www.npmjs.com/package/valid-url" rel="noreferrer">valid-url</a> to validate some URLs using JSFiddle so that I can share it later. I tried adding a link to the <code>index.js</code> file from Github (<a href="https://raw.githubusercontent.com/ogt/valid-url/master/index.js" rel="noreferrer">https://raw.githubusercontent.com/ogt/valid-url/master/index.js</a>) but Fiddle says:</p>
  
  <blockquote>
    <p>Github is not a CDN, using it as such will cause issues with loading the file. Do you still with to it?</p>
  </blockquote>
  
  <p>And obviously when I try to use it, an error is thrown:</p>
  
  <blockquote>
    <p>Refused to execute script from [...] because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled.</p>
  </blockquote>
  
  <p>So, is there any way to use npm packages in a JSFiddle? Or any workaround to achieve this?</p>
