Package Exports

jscpd

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (jscpd) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Copy/paste detector for JavaScript and CoffeeScript code

jscpd is a tool for detect copy/past "design pattern" in JavaScript and CoffeeScript code.

Status

Installation

npm install jscpd -g

Usage

jscpd --path my_project/ --languages js,coffee #scan for js and coffee files for duplicates

jscpd -f **/*.js -e **/node_modules/**

jscpd --files **/*.js --exclude **/*.min.js --output report.xml

If you have file .cpd.yaml in your directory

#.cpd.yaml
path:
  - fixtures/
languages:
  - js
  - coffee
exclude:
  - "**/*.min.js"

# coffeescript
jscpd = require('jspd')
result = jscpd::run
    path: 'my/project/folder'
    files: '**/*.js'
    exclude: ['**/*.min.js', '**/node_modules/**']
