title: Using chrome extension apis in typescript
body: <p>I'm building a chrome extension written in TypeScript. I'm using WebStorm and I added the <code>chrome-DefiniteltyTyped</code> library in my project.</p>
  
  <p>However, when I write this in my typescript code : <code>chrome.extension.getURL</code>
  I got an error : <code>cannot find name 'chrome'</code>.</p>
  
  <p>Because of this, my javascript file is not generated and I cannot use it in my extension.</p>
  
  <p>Do you guys have any solution?</p>
