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 supported versions matrix:

Version	Transaction Support	Rules Support	Type of Support
1.0			Full-stack use case 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

Comparison with existing support for JavaScript in CAST AIP

CAST AIP has provided support for analyzing JavaScript via its J2EE 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 J2EE 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 J2EE application.
• If the back end web client part of a .NET or J2EE application is analyzed with the AngularJS extension and with the native .NET/J2EE 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

CAST AIP compatibility

This extension is compatible with:

CAST AIP release	Supported
8.3.x
8.2.x
8.1.x
8.0.x
7.3.4 and all higher 7.3.x releases

Supported DBMS servers

This extension is compatible with the following DBMS servers:

CAST AIP release	CSS	Oracle	Microsoft
All supported releases

Prerequisites

An installation of any compatible release of CAST AIP (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
• Web Services Linker

Packaging, delivering and analyzing your source code

Once the extension is downloaded and installed, you can nowpackage 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

Objects

The following specific objects are displayed in CAST Enlighten:

Icon	Description
	AngularJS Application
	AngularJS Controller
	AngularJS Directive
	AngularJS Directive Controller
	AngularJS Directive Link Function
	AngularJS Factory
	AngularJS Model function
	AngularJS Model variable
	AngularJS Service
	AngularJS Get Resource Service
	AngularJS Post Resource Service
	AngularJS Put Resource Service
	AngularJS Delete Resource Service
	AngularJS Get Http Service
	AngularJS Post Http Service

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).

Known Limitations

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

• 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(),
