Description

This extension provides support for AngularJS.

In what situation should you install this extension?

If your Web application contains AngularJS source code and you want to view these object types and their links with other objects, then you should install this extension:

• Creates AngularJS object structure (see below)
• Creates links between these objects and links between HTML files and controller scope elements
• Directives are partly handled:
  • links between HTML tags and directives are handled
  • links between HTML attributes in directive sections and directive scope items are handled

Regarding Front-End to Back-End connections, we do support the following cross-technology stacks:

AngularJS Front-End connected JEE Back-End	AngularJS Front-End connected Node.js Back-End

Supported AngularJS versions

The following table displays the list of AngularJS versions that this extension supports:

AngularJS Version	Transaction Support	Rules Support	Type of Support

1.2			Fullstack use case support
1.3			Fullstack use case support
1.4			Fullstack use case support
1.5			Fullstack use case support
1.6			Fullstack use case support
1.7			Fullstack use case support
1.8			Fullstack use case support

Comparison with existing support for JavaScript

CAST AIP has provided support for analyzing JavaScript via its JEE and .NET analyzers (provided out of box in CAST AIP) for some time now. The HTML5/JavaScript extension (on which the AngularJS extension depends) also provides support for JavaScript but with a focus on web applications. CAST highly recommends that you use this extension if your Application contains JavaScript and more specifically if you want to analyze a web application, however you should take note of the following:

• You should ensure that you configure the extension to NOT analyze the back end web client part of a .NET or JEE application.
• You should ensure that you configure the extension to ONLY analyze the front end web application built with the HTML5/JavaScript that communicates with the back end web client part of a .NET or JEE application.
• If the back end web client part of a .NET or JEE application is analyzed with the AngularJS extension and with the native .NET/JEE analyzers, then your results will reflect this - there will be duplicate objects and links (i.e. from the analyzer and from the extension) therefore impacting results and creating erroneous Function Point data.

Function Point, Quality and Sizing support

This extension provides the following support:

• Function Points (transactions): a green tick indicates that OMG Function Point counting and Transaction Risk Index are supported
• Quality and Sizing: a green tick indicates that CAST can measure size and that a minimum set of Quality Rules exist

Function Points (transactions)	Quality and Sizing	Security

AIP Core compatibility

This extension is compatible with:

AIP Core release	Supported
8.3.x

Supported DBMS servers

DBMS	Supported?
CSS / PostgreSQL

Prerequisites

An installation of any compatible release of AIP Core (see table above)

Dependencies with other extensions

Some CAST extensions require the presence of other CAST extensions in order to function correctly. The AngularJS extension requires that the following other CAST extensions are also installed:

• HTML5/JavaScript
• Universal Linker

Download and installation instructions

The extension will be automatically downloaded and installed in CAST Console. You can manage the extension using the Application - Extensions interface:

Packaging, delivering and analyzing your source code

Once the extension is downloaded and installed, you can now package your source code and run an analysis. The process of packaging, delivering and analyzing your source code is described below:

What results can you expect?

Once the analysis/snapshot generation has completed, you can view the results in the normal manner (for example via CAST Enlighten):

E.g. : AngularJS Front-end connected to Node.js Back-end

E.g. : AngularJS Front-end connected to JEE/Spring MVC Back-end

Web Service calls

The following libraries are supported for Web Service HTTP calls:

• $http
• $resource
• Restangular

Once the AngularJS extension analysis is finished, the analyzer will output the final number of web service calls created.

These web services are resolved to web service operations on the server side for the following supported frameworks: Node.js, JAX-RS, Spring MVC:

$http

$http.get('/api')
	.then(function () {
		return $injector.get('api');
	}, function () {
		return $injector.get('localStorage');
	});

$http.delete('/api/todos')
	.then(function success() {
		return store.todos;
	}, function error() {
		angular.copy(originalTodos, store.todos);
		return originalTodos;
	});

$resource

return $resource('resources/scenarios/:id/mapping', {'id':'@id'}, {
    'query': { method: 'GET', isArray: false },
	'update': {method:'PUT', isArray: false }
});  

Restangular

angular.module('Patient', [])
	.service('Patient', ['$rootScope','Restangular', function($rootScope, Restangular){
	var Patient	= Restangular.service('patients');
	Restangular.extendModel('patients', function(model){
		model.fullname = function(){
			return this.fname+' '+this.sname;
		};
		model.over18 = function(){
			if(this.age >= 18){
				return 'yes';
			}else{
				return 'no';
			}
			
		};
		return model;
	})

	return Patient;
}]);

angular.module('PatientsService', []).service('PatientsService', ['$rootScope','Restangular', 'Patient', function($rootScope, Restangular, Patient){
	var service = {
		currentPatient: [],
		setCurrentPatient: function(patient){
			this.currentPatient = patient;
			$rootScope.$broadcast('currentPatient.change', patient);
		},
		getPatients: function(){
				Patient.getList().then(function(patients){
				$rootScope.$broadcast('patientList.change', patients);
			})
		},
		removePatient: function(patient){
			patient.remove().then(function(){
				//refresh list
				this.getList();
			});
		},
		createPatient: function(newPatient){
			console.log(newPatient);
		}
	};

	return service;
}]);
  
angular.module('PatientsAppointmentsCtrl', ['ngGrid']).controller('PatientsAppointmentsCtrl', ['$scope', 'PatientsService', 'Patient', function($scope, PatientsService, Patient){

	$scope.appointments = [];

	$scope.$on('currentPatient.change', function(event, currentPatient){
		//get appointments
		if(currentPatient != null){
			currentPatient.getList('appointments').then(function(appointments){
				console.log(appointments);
				$scope.appointments = appointments;
			})
		}else{
			$scope.appointments = [];
		}
		
		
	})

Technical notes

AngularJS Service objects and Transactions

AngularJS Service objects are not considered by CAST AIP as being part of any transaction (they are considered as technical function points). Instead, the AngularJS Service's functions are considered to be part of the transaction. Therefore when looking at the results of an AngularJS analysis, links to the AngularJS Service's functions should be checked to ensure that the expected transactions exist. Transactions within AngularJS are ALWAYS from functions or methods to functions or methods (objects which are executable).

Avoid using unsanitized AngularJS application (1020546)

The AngularJS Quality Rule Avoid using unsanitized AngularJS application (1020546) is designed to list violations for missing items. When this type of Quality Rule is violated, it is not possible to place a bookmark at the location in the code where the violation occurs since the violation is for something that is missing. In this situation, for this specific Quality Rule, the following is done:

• When the AngularJS application is defined in an HTML file (as is sometimes the case) the bookmark will be placed on the entire HTML file.
• If the no HTML file associated to the AngularJS application can be found then no bookmark will be created at all. In this situation, the message "No associated html file" will be visible in the analysis log file and the following error message will be displayed in the legacy CAST Engineering Dashboard when an attempt is made to view the code of the violation: The source file is absent from the Local Site. Page cannot be displayed.

Known Limitations

In this section we list the most significant functional limitations that may affect the analysis of applications using AngularJS:

AngularJS objects declared with prototypes

The extension does not detect AngularJS objects when they are declared with prototype. For example:

xxx.service('ContentService', ['$rootScope', '$window', '$resource', '$q', '$log', 'ManageContentURIs', attContent.content]);

attContent.content.prototype.retrieveContent = function(criteria, useStubs) {
var useStub = useStubs?useStubs:false;
var deferred = this.q.defer(),
