Getting Started

This plugin requires Grunt ~0.4.2

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-weightwatchsy --save-dev

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


The "weightwatchsy" task


In your project's Gruntfile, the weightwatchsy task is available to use.

You can run grunt weightwatchsy standalone Or add it to an existing task: grunt.registerTask('test', ['clean', 'weightwatchsy']);


  //Prettifies file sizes to readable format
  human: <true>,
  //Path where to save results
  location: <'dist/weightwatchsy.json'>,
  //Sums up assets' sizes per extension type
  aggregate: <['.txt', '.css', '.js', '.png', '.jpg']>,
   * Allows for grouping asset types e.g.
   * {
   *   text: ['.css', '.js']
   * }
  groups: <{}>,
   * Allows breaking the build by e.g. stating
   * {
   *   aggregations: {
   *     css: 1000
   *   },
   *   groups: {
   *     text: 20000
   *   },
   *   summary: {
   *     size: 50000,
   *     average: 250
   *   }
   * }
   break: <{
     file: {},
     aggregations: {},
     summary: {}
   //Aborts grunt immediately if false and a `break`-condition holds
   warn: <true>,
   //Excludes dependencies by name (from extensions and total size etc.)
   exclusions: <[]>,
   //Variations of files e.g .gz versions of all .js and css files which should be
   //treated separately and not be aggregated all as .gz
   variations: <[]>,
   //Keep history over builds with limit
   history: <{
     enabled: <false>,
     limit: <10>

An example configuration can be found here and if you want to check the options you might want to check the Gruntfile itself.

Developing & Contributing

Developing on the task alone is fairly easy just git clone then cd grunt-weightwatchsy. From there one has to link the package to itself via npm link && npm link grunt-weightwatchsy which will allow for calling grunt dev. Now just work the task/weightwatchsy.js and check results - feel free to submit a pull-request!
