Return value from firebase database Javascript

Question

My attempts at retrieving the value of a firebase record are failing. My JSON is as follows:

{
  "accounts" : {
    "-KRPSyO4B48IpBnHBTYg" : {
      "dateCreated" : "",
      "email" : "",
      "provider" : "",
      "userId" : ""
    }
  },
  "products" : {
    "-KUKRafaNurpFhGF4jQa" : {
      "name" : ""

    }
  },
  "total" : 1
}

I'm trying to return the value of "total". Here's the latest attampt:

var totals = firebase.database().ref('total').once('value', function(products) {});
    $scope.totalPosts = totals;

and my HTML:

<div class="card" ng-controller="myController">{{totalPosts}}</div>

All I'm getting is an empty {}. What am I doing wrong?

Thanks in advance!

Firebase queries are asynchronous, try this.

firebase.database().ref('total').once('value', function(products) {
  $scope.totalPosts = products.val();
});
