Am I using outdated code? Also, I set the rules of the database so read and write are true. That makes the database changeable from any device. When I try searching on stack overflow, firebase is not defined, I get irrelevant answers.

</html>You have to use the getDatabase function you imported here:
import { getDatabase } from "https://www.gstatic.com/firebasejs/9.6.7/firebase-database.js";
So, you can do const db = getDatabase(), and access your realtime using that.
Your snippet with the fix:
