Firebase

Take firebase for example, let's say you are adding google analytics to your project with firebase integration, you could directly import from your current url:

<body>
  <!-- Insert these scripts at the bottom of the HTML, but before you use any Firebase services -->

  <!-- Firebase App (the core Firebase SDK) is always required and must be listed first -->
  <script src="/__/firebase/8.2.8/firebase-app.js"></script>

  <!-- If you enabled Analytics in your project, add the Firebase SDK for Analytics -->
  <script src="/__/firebase/8.2.8/firebase-analytics.js"></script>

  <!-- Add Firebase products that you want to use -->
  <script src="/__/firebase/8.2.8/firebase-auth.js"></script>
  <script src="/__/firebase/8.2.8/firebase-firestore.js"></script>
</body>

You could directly load firebase script from url such as https://docs.let.sh/__/firebase/8.2.8/firebase-analytics.js (take current site for example)

Besides, in your development stage, the plugin system will also avaliable in your lets dev endpoint.
