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)
