Analyzes an AMD project's Javascript (using madge), generating a report of largest Javascript dependencies.

Dependencies are sorted in descending order by Uglified filesize.

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-big-assets --save-dev

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


The "big_assets" task


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

  big_assets: {
    options: {
      base: 'public/javascripts'  // base path to project Javascript (no trailing slash), 
      reportPath: 'target/grunt/big-assets.html'  // path to output a report in HTML format (optional) 
    files: ['public/javascripts/**/*.js']



Type: String Default value: ''

Base path to the project Javascript, relative to the Gruntfile.


Type: object Default value:

  format: 'amd',
  findNestedDependencies: false,
  requireConfigFile: ''

Configuration options to pass on to Madge (full list of options).
