  password: 'secretPassword',
  displayName: 'John Doe',
  photoURL: 'http://www.example.com/12345678/photo.png',
  disabled: false

.then(function(userRecord) {
  console.log('Successfully created new user:', userRecord.uid);
})
.catch(function(error) {
  console.log('Error creating new user:', error);
});

var db = admin.firestore();
var docRef = db.collection('users').doc('alovelace');

var setAda = docRef.set({
  first: 'Ada',
  last: 'Lovelace',
  born: 1815
});

var db = admin.database();
var ref = db.ref('server/saving-data/fireblog');

usersRef.set({
  alanisawesome: {
    date_of_birth: 'June 23, 1912',
    full_name: 'Alan Turing'

    time: '2:45'
  },
  token: registrationToken
};

admin.messaging().send(message)
  .then((response) => {

  })
  .catch((error) => {
    console.log('Error sending message:', error);
  });
