Uncaught ReferenceError: Firebase is not defined

I am trying to follow the tutorial on designing a database in firebase, but I am getting the following error in the JavaScript console:

Uncaught ReferenceError: Firebase is not defined

Here is the link to the tutorial, and the code snippet that I was trying to run in the JavaScript console is: https://www.firebase.com/blog/2014-11-04-firebase-realtime-queries.html

var ref = new Firebase("https://dinosaur-facts.firebaseio.com/dinosaurs");
ref.orderByChild("height").on("child_added", function(snapshot) {
  console.log(snapshot.key() + " was " + snapshot.val().height + " meters tall");
});
Solution

  • In the heading, include the following:

    <head>
    <script src="https://www.gstatic.com/firebasejs/6.1.0/firebase.js"></script>
    
  </head>

    That'll solve the problem.
