this module is a tool to append/update copyright/license notice in target source files, based on scope management.


For installation, run

npm install copyrightizen -g

to run copyrightizen against some file with glob patterns, run

copyrightizen --paths src/*.ts

to run copyrightizen with config file, just run

copyrightizen [--config custom.config.js]


  • [x] configuration file to control various features
  • [x] scope management (similar to Intellij IDE's scope concept)
  • [x] custom copyright text or custom file template
    • [ ] support dynamic template
  • [x] update strategy to control update or skip update the existing license
  • [x] custom Regexp rule to match custom copyright format
  • [x] full functionality supported in command line
    • [x] seamless support for multi files input from command line (useful for tools like lint-staged)


Config File

thanks to cosmiconfig, Copyrightizen support a bunch of config variants:

  • a copyrightizen property in package.json
  • a .copyrightizenrc file in JSON or YAML format
  • a .copyrightizenrc.json file
  • a .copyrightizenrc.yaml, .copyrightizenrc.yml, or .copyrightizenrc.js file
  • a copyrightizen.config.js file exporting a JS object

A sample content of the config should look like this:

  "licenseText": "Copyright (c) Humans on Mars",
  "updateStrategy": "update",
  "scopes": [
      "name": "scopeA",
      "paths": ["*.ts*"],
      "licenseText": "Copyright (c) Humans on Moon",
      "updateStrategy": "update",

NOTE: For the detail constraints of the supported configurations, see the JSON schema.

NOTE: Configuration uses globby for glob matching, it support glob features what globby supports

Options Precedence order

From lowest to highest

  1. default global Options
  2. global Options from config file(if config is enabled and a config file is found)
  3. command line global options
  4. related scope options if available

Scopes Precedence order

the order of scopes within config file matters.

The global scope (aka default config) has the lowest priority. The later a scope is defined in the scopes list, the higher priority it has.
