Description

This extension provides support for HTML5/JavaScript.

In what situation should you install this extension?

If your Web application contains HTML5/JavaScript source code and you want to view these object types and their links with other objects, then you should install this extension:

• The extension provides support for Automated Function Point counting.
• Handles pure JavaScript code:
  
  • creates "functions"
  • local call links between function calls and functions inside each JavaScript file.
• Handles html files: 
  • creates one "HTML5 Source Code" object that is the caller of html to js links and a transaction entry point
  • broadcasts tags and attributes/values to other CAST extensions such as AngularJS. Other extensions will not need to analyze the files themselves.
• Files whose names end with .min.js and Spec.js (tests) are ignored.
• Checksum, number of code lines, number of comment lines, comments are present.
• Local and global resolution is done when function is called directly through its name (inference engine resolution is not available).
• For global resolution, caller is searched in all .js files. If only one callee is found, a link is created. If several callees are found, the analyzer watches inclusions in html files to see if it can filter the callee. It nothing is found in html files to filter, links are created to all possible callees.

Files analyzed

• *.html
• *.js
• *.css

Transaction configuration

HTML5 source code: it represents the whole HTML file content.

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

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 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 HTML5/JavaScript 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.
