Answer 1

Set configuration and initialize firebase:

  var firebaseConfig = {
      //You can get the necessary information in you project console
  };
  // Initialize Firebase
  firebase.initializeApp(firebaseConfig);

This will give you the keys of your reference children:

var myRef = firebase.database().ref(//path to you data);
var keys = [];  
myRef.once("value", function(snapshot){
  documents=Object.keys(snapshot.val());
  for(d in documents){
    keys.push(documents[d]);
  }
}
