Description

The HTML5/JavaScript Analyzer can 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:

• 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.
• Automated Function Point counting.

Technology support

See HTML5 and JavaScript - Technical Notes for information about:

• Web Services support

You may find that the number of files delivered is more than then number of files reported after analysis. This is due to the following:

• 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.
• some bundled javascript files are automatically excluded from the analysis, typically minified files (extension.min.js) or disguised minified files (extension.js), but for files containing one or a few very long lines, a specific calculation is actioned by the analyzer. 
• some files that have been included in the analysis may not be saved in the CAST Analysis Service schema because they do not contain any useful information, i.e. they do not contain any technical sections such as functions which would lead to the creation of a specific object.

Since version 2.1.14-funcrel, files which are excluded from analysis are considered as external libraries when they are included in analyzed code. For each file, a “HTML5 JavaScript Source Code” is created with the external property set to “True”. This means that these files are not included in rule checks or other computations.

Function Point, Quality and Sizing 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.

Known Limitations

• Creation and detection of object using “prototype” is not supported.
• When HTML5/JavaScript source code is used as the “source” or “destination” in a Reference Pattern it will be ignored when the analysis is run - this is due to a limitation in the way the analyzer functions.
