grunt-delete-sync

Syncs file deletion from one directory to another.

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-delete-sync --save-dev

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

grunt.loadNpmTasks('grunt-delete-sync');

This task looks through the files defined in src, if they do not exist in the syncWith directory, they are removed.

Example:

delete_sync: {
  dist: {
    cwd: 'targetDir',
    src: ['**', '!**/*.css'],
    syncWith: 'src'
  }
},
