title: How to find an unminified angular source to replace opensource.keycdn.com on Plunker?
body: <p>I'm experiencing a weird error on Plunker, but the line having the issue is buried in the unreadable "minified" version of angular.js, specifically: </p>
  
  <blockquote>
    <p>... at <a href="https://opensource.keycdn.com/angularjs/1.5.8/angular.min.js:6:412" rel="nofollow">https://opensource.keycdn.com/angularjs/1.5.8/angular.min.js:6:412</a></p>
  </blockquote>
  
  <p>So I want to look at the unminified version of angular.js to see if the error makes more sense. </p>
  
  <p>Here's the call to the minified library supplied by plunker:</p>
  
  <pre><code>&lt;script data-require="angularjs@1.5.8" 
    data-semver="1.5.8" 
    src="https://opensource.keycdn.com/angularjs/1.5.8/angular.min.js"&gt;
  &lt;/script&gt; 
  </code></pre>
  
  <p>And I changed it to:</p>
  
  <pre><code>../1.5.8/angular.js
  </code></pre>
  
  <p>But I'm getting a <a href="https://opensource.keycdn.com/angularjs/1.5.8/angular.js" rel="nofollow">404</a>. My guess is that <code>opensource.keycdn.com</code> only supplies minified versions of libraries. How do I tell Plunker I want to use a non-minified version?</p>
