grunt-groundskeeper

Remove console statements, debugger and specific blocks of code

Notice

If you're using UglifyJS2 then you most likely don't need this package at all. You can just use the drop_debugger and drop_console to achieve the same effect.

If you're using the pragmas function, you might achieve the same effect using conditional compilation.

On the other hand if you don't use UglifyJS2 then go ahead and keep reading :)

Getting Started

This plugin requires Grunt ~0.4.0

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-groundskeeper --save-dev

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

grunt.loadNpmTasks('grunt-groundskeeper');

This plugin was designed to work with Grunt 0.4.x. If you're still using grunt v0.3.x it's strongly recommended that you upgrade, but in case you can't please use v0.3.2.

Usage Examples

groundskeeper: {
  compile: {
    files: {
      'path/to/result.js': 'path/to/source.js', // 1:1 compile
      'path/to/another.js': ['path/to/sources/*.js', 'path/to/more/*.js'] // clean up and concat into single file
    },
    options: {  // this options only affect the compile task
        console: false
    }
  },

  glob_to_multiple: { // if multiple files are given, this will keep the same folder structure and files
    expand: true,
    cwd: 'path/to',
    src: ['*.js'],
    dest: 'path/to/dest/',
    ext: '.js'
  },

  options: {
    console: true,                          // don't remove console statements
    debugger: true,                         // don't remove debugger statements
    pragmas: ['development', 'validation'], // don't remove `development` and `validation` pragmas
    namespace: ['App.logger'],              // Remove functions that live inside the App.logger namespace
    replace: '"0"'                          // Replace removed statements for the given string (note the extra quotes)
  }
}
