grunt-cleanempty

Clean empty files and folders.

Getting Started

This plugin requires Grunt >=0.4

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-cleanempty --save-dev

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

grunt.loadNpmTasks('grunt-cleanempty');

The "cleanempty" task

Overview

In your project's Gruntfile, add a section named cleanempty to the data object passed into grunt.initConfig().

grunt.initConfig({
  cleanempty: {
    options: {
      // Task-specific options go here.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    },
  },
});

Options

options.files

Type: Boolean
Default value: true

Remove empty files or not.

options.folders

Type: Boolean
Default value: true

Remove empty folders or not.

options.force

Type: Boolean
Default value: false

Override the task from blocking deletion of folders outside current working dir (CWD). Use with caution.

Consider folders that only have junk files in them to be empty. Use in conjunction with options.folders set to true.
