grunt-nice-package

Opinionated package.json validator

You can read the description of each package.json property here. Example package.json that passes all checks (because it is using this module!) is kensho/ng-describe/package.json.

Install

npm install grunt-nice-package --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-nice-package');
grunt.initConfig({
  'nice-package': {
    all: {
      options: {
        // make sure package.json ends with \n\n, default false
        blankLine: true|false,
        version: function (value) {
          // strict version number validation
          return (/\d{1,2}\.\d{1,2}\.\d{1,2}/).test(value);
        }
      }
    }
  }
});

Alternative: default options

You can load the task with default options without specifying the configuration object

grunt.loadNpmTasks('grunt-nice-package');
grunt.registerTask('default', ['nice-package']);

Note: you can use nicePackage as alias to nice-package task name

 grunt.initConfig({
   nicePackage: {
     all: { ... }
   }
  });

Install without Grunt

If you don't want to use grunt, but still need this project, run it via grunty

npm install -D grunt-nice-package grunty

Then add the following to the scripts section

{
  "scripts": {
    "nice": "grunty grunt-nice-package nice-package"
  }
}

Validator functions

Please return true if the check passes from custom validation functions.

After the property validators pass, package.json is further checked using package-json-validator by Nick Sullivan. It will check the required properties, and provide suggestions for the recommended ones.

Tight versions

The fix step in this task removes all fuzzy symbols from declared versions (~, ^), leaving just the numbers.

"dependencies": {         "dependencies": {
  "foo": "^0.1.0",  ==>     "foo": "0.1.0",
  "bar": "~1.0.0"           "bar": "1.0.0"
}                         }

Options

You can define a validation function for any property of the package.json, by default the validation will check:

name
version
description
license or licenses
keywords (array of strings)

For complete list see nice_package.js for details.
