Answer 1

I wrote "/" to ref and I got all the things.

      
      const firebaseMain = firebase
      .app()
      .database('https://XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/')
      .ref('/');
      
      console.log("CHILDREN:");
      firebaseMain.ref.once('value', function(snapshot) {
        console.log(JSON.stringify(snapshot.val()));
        firebaseReferences=snapshot.val();
        console.log("\x1b[32m","references: --> TYPE"+typeof firebaseReferences );
      });
