I have an PWA (Progressive Web App) and i import all modules of firebase: (firebase@9.6.0)
import * as firebase from “firebase/app”
import “firebase/auth”
import “firebase/database”

I have an error when I use:
const ref = firebase.database().ref();

Error: The module database does not exists.
How can I do?

If you added firebase via script tags, it needs to be of type module. See the docs: https://firebase.google.com/docs/web/alt-setup
