title: Import Typescript file in Javascript
body: <p>I'm making a Chrome extension and I'm trying to import a Typescript file in Javascript.
  Both files are next to each others.</p>
  
  <p>I'm importing it this way:</p>
  
  <pre><code>import { ApiParsing } from './ApiParsing.ts';
  </code></pre>
  
  <p>When I'm using the extension I have the following error:</p>
  
  <pre><code>Failed to load module script: The server responded with a non-JavaScript MIME type of "". Strict MIME type checking is enforced for module scripts per HTML spec.
  </code></pre>
