const admin = require('firebase-admin');

  credential: admin.credential.cert('./movies-387bf-firebase-adminsdk-4hoi8-c52699119b.json'),
  databaseURL: 'https://movies-387bf.firebaseio.com',

// Get a database reference to our blog
const db = admin.database();

// creating a starting path in our database
const ref = db.ref('server/saving-data/fireblog');

// create a child node of the above path and write the following data to it
const usersRef = ref.child('users');
usersRef.set({
  alanisawesome: {
    date_of_birth: 'June 23, 1912',
    full_name: 'Alan Turing',
  },
  gracehop: {
    date_of_birth: 'December 9, 1906',
