Navigating Parse object attributes within AngularJS

Question

Navigating Parse object attributes within AngularJS

Currently, I am in the process of developing an AngularJS application that utilizes data from a parse-server backend. To retrieve this data, I use services that are called from my controllers. However, as Parse objects require all properties to be accessed through a get function, my HTML code ends up cluttered with lines like

<p>{{myObject.get('title')}</p>}

.

My preference would be to access properties just like a regular object, such as myObject.title, but I have not been able to locate any guidance on best practices for integrating the Parse JS SDK with AngularJS.

I have come across references to an example of Parse and AngularJS boilerplate created by BRANDiD, but unfortunately, the links to their actual code and website appear to be inaccessible.

If anyone has insights on how to tackle this issue effectively, I would greatly appreciate it!

One potential solution I propose is creating a specialized service that retrieves data in JSON format from a parse response.

(Hypothetical) Code Implementation:

Service Logic:

app.service('Library', function($q) {
  return {
    findBookById: function(id) {

      var deferred = $q.defer();

      // logic for querying the Parse database
      var Book = Parse.Object.extend("Book");
      var query = new Parse.Query(Book);
      query.equalTo("book_id", id);

      query.first({
        success: function(response) {
          // converting to JSON facilitates easy access to properties
          // e.g. book.title instead of book.get('title')
          deferred.resolve(response.toJSON());
        },
        error: function(err) {
          deferred.reject(err);
        }
      });
      return deferred.promise;
    }
  };
});

Controller Usage:

app.controller('LibraryCtrl', function($scope, Library) {
  Library
    .findById(10)
    .then(function(book) {
      $scope.book = book;
    })
    .catch(function(err) {
      alert('An error has occurred: ' + err.message);
    });
});

View Section:

<p>Title: {{book.title}}</p>
