ComplexityCounter

A tool to crudely calculate code complexity per file.

Assumptions

I'm calculating complexity assuming code features which result in code branches increase complexity by one point.

Features:

• if statements
• ternary conditions
• logical OR
• logical AND
• nullish coalescing
• switch cases
• optional chaining

Flags

-extensionsRegex "\\.jsx$"

• A regex which can be used to change what files you're including.
• Defaults to "\\.(js|jsx|ts|jsx)$"

-directory ~/Code/Project/src

• Which directory to run the search on
• Defaults to "./"

-exclusionsRegex __tests__

• Match on any files you don't want included
• Defaults to "(__snapshots__|__tests__|test\\.(js|ts|jsx|tsx))"

-outputType json

• Specify json or csv as an output type
• Defaults to "csv"

JSON Output

[
 {
  "filepath": "TestFile.js",
  "lineCount": 50,
  "codeLines": 48,
  "complexity": 7
 }
]

CSV Output
