CodePudding user response：

If you want to get a reference to the root of the database, you can call getReference without any value:

rootReference = FirebaseDatabase.getInstance().getReference();

Also see the documentation for getReference() without parameters, which says:

public DatabaseReference getReference ()

Gets a DatabaseReference for the database root node.

Returns: A DatabaseReference pointing to the root node.

Seems you are using realtime database that is called firebase reference url

you can try as:

import { getDatabase, ref, child, get } from "firebase/database";



    const dbRef = ref(getDatabase());
get(child(dbRef, `users/${userId}`)).then((snapshot) => {
  if (snapshot.exists()) {
    console.log(snapshot.val());
  } else {
    console.log("No data available");
  }
}).catch((error) => {
  console.error(error);
});

You can find your Realtime Database URL in the Realtime Database section of the Firebase console.

Depending on the location of the database, the database URL will be in one of the following forms: https:// DATABASE_NAME . firebaseio.com (for databases in us-central1 ) for more details on it you can access the documentation on https://firebase.google.com/docs/database/web/read-and-write
