Info

Summary: This document provides basic information about the extension providing HTML5/JavaScript support for Web applications.


Info

What's new:

  • Support of Object Oriented ECMA6 annotations (classes, constructors, try/catch...)
  • Support of const, let arrows ECMA6 annotations
  • Support of Javascript call(), window.function(), bind(), prototype and prototype inheritance
  • HttpRequest web service (<a href="">)
  • 18 new Quality Rules

Description

In what situation should you install this extension?

The analyzer could be used if your application is a Web Application, has HTML/Javascript/CSS files and/or contains HTML/Javascript fragments embedded into JEE and .NET files (for example).

The analyzer provides the following features:

  • Automated Function Point counting.
  • 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. If nothing is found in html files to filter, links are created to all possible callees.

Files analyzed

Icon(s)FileExtensionNote

HTML

*.html, *.htm, *.xhtml
  • Supports HTML/XHTML versions 1 - 5.
  • 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.

Javascript*.js

Supports:

  • JavaScript 1 to 1.8.1.
  • JavaScript ECMA 6

See also JavaScript below for more information.

Cascading Style Sheet*.css

Supports CSS 1 - 3.

 

Java Server Page*.jsp

Supports JSP 1.1 - 2.3.

See JSP below for more information.

Active Server Page*.asp, *.aspx

See (Classic) ASP below for more information.

HTML Components*.htcHTC files contain html, javascript fragments that will be parsed. Created objects will be linked to the HTC file.

ASP.NET MVC Razor*.cshtml

See ASP.NET MVC Razor below for more information.


Info
Note that by default some files are automatically excluded from the analysis, typically third-party frameworks which are not required. Please see the filters.json file located at the root of the extension folder for a complete list of default exclusions.

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 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 when using the extension with CAST AIP ≤ 8.2.x

  • 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 HTML5/JavaScript 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.
Info
Note that in CAST AIP 8.3.x, support for analyzing JavaScript has been withdrawn from the JEE and .NET analyzers.

Support of JavaScript in this extension

  • JavaScript (1 to 1.8.1):
    • Javascript call(), function(), bind(), prototype and prototype inheritance are supported
    • creates Functions, Classes and Constructors
    • local call links between function calls and functions inside each JavaScript file are created

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
