eslint-plugin-license-header

Rules to validate the presence of license headers in source files.

Installation

npm install eslint-plugin-license-header --save-dev

Usage

Add license-header to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
  "plugins": [
    "license-header"
  ]
}

Header configuration

When enabling the rule specify the license header template as a path:

{
  "rules": {
    "license-header/header": [ "error", "./resources/license-header.js" ]
  }
}

Alternatively, specify the license header as raw text:

{
  "rules": {
    "license-header/header": [
      "error",
      [
          "/***********************************************",
          " * Copyright My Company",
          " * Copyright " + new Date().getFullYear(),
          " ***********************************************/",
      ]
    ]
  }
}

Flat config

In eslint@9 you can consume the library using a flat configuration, too:

import licenseHeader from "eslint-plugin-license-header";

export default [
  {
    files: '**/*.js',
    plugins: {
      'license-header': licenseHeader
    },
    rules: {
      "license-header/header": ...
    }
  }
];

Autofix

You may auto-fix your source files, adding or updating a given license header:

eslint --fix .
