AngularJs is being used to extract data from Firebase with the help of $value, $id, and

I have been working on retrieving data from Firebase in my HTML using AngularJS. Everything is functioning well, however, when I access the child node, the data is displayed in an unexpected format. Please refer to the images below for more details:

This is the Json File imported to Firebase:

Here is how the data looks in Firebase:

And this is how the data appears in the HTML:

This is what I was expecting:

In my controller, I am trying to retrieve data from Firebase like this:

$scope.locService = $rootScope.service;
  var serviceRef = new Firebase(FIREBASE_URL+"ABC/location/"+$rootScope.location+"/services/"+$rootScope.service+"/"+$rootScope.serviceDetail+"");
  $scope.details = $firebaseArray(serviceRef);

The values of $rootScope are correct but the returned data is not in the expected format with $id, $value, $priority.

In my HTML:

<div class="content has-header">
      <h2>{{details[0]}}</h2>
</div>

If anyone can provide some assistance, it would be greatly appreciated. Thank you in advance for any suggestions.

AngularFire takes a set of Firebase DataSnapshots and turns them into a synchronized array. These Snapshots not only contain the data, but also include additional information like the key and priority. By using the $ prefix, AngularFire ensures that this data is available for each item in the array.

If you're working with primitive values and want access to important details like the key, AngularFire will wrap the primitive in an object and provide the value through the $value property.

For more information on meta fields, check out the AngularFire documentation.

If you prefer a different approach, consider using $firebaseObject() or adjusting your JSON structure accordingly.

In your specific scenario, utilizing $firebaseObject() may be the best option.

$scope.locService = $rootScope.service;
var serviceRef = new Firebase(FIREBASE_URL+"ABC/location/"+$rootScope.location+"/services/"+$rootScope.service+"/"+$rootScope.serviceDetail+"");
$scope.details = $firebaseObject(serviceRef);
