JS Complexity Analysis

JavaScript Complexity Analysis for Visual Studio Code

Uses [ESComplex] to produce a complexity analysis report for a JavaScript project or file. The following [metrics] can calculated:

• Lines of code
• Number of parameters
• Cyclomatic complexity
• Halstead metrics
• Maintainability

Installation

• Install the latest Visual Studio Code.
• In the command palette (Ctrl-Shift-P or Cmd-Shift-P or F1) select Install Extension and choose JS Complexity Analysis Report.

Usage

This extenson uses typhonjs-escomplex to analyse source files. Currently it utilizes babylon w/ all plugins enabled to analyse source code, so it should support most JS syntax.

Project analysis

Produces a per function complexity analysis report of all .js files in the project. Open command palette F1 and search for Project complexity analysis.

By default uses project's jsconfig.json configuration for including and excluding files, but files can also be configured using include and exclude glob patterns. Select Code --> Preferences --> User Settings or Workspace Settings. For example:

"complexityAnalysis.exclude": [
    "**/bower_components/**"
],

"complexityAnalysis.include": [
    "**/app/**/*.js"
]

File analysis

Produces a per function complexity analysis report of currently open file. Open command palette F1 and search for File complexity analysis.
