Saving Data to Firebase
There are three firebase functions that will add or modify your data:

var ref = firebase.database().ref('/some/path');
var obj = {someAttribute: true};
ref.push(obj);   // Creates a new ref with a new "push key"
ref.set(obj);    // Overwrites the path
ref.update(obj); // Updates only the specified attributes
