Build Status

Use rflynn's aggressive, lossy image optimizer, imgmin, in grunt! Unfortunately, you'll have to deal with the dependencies on your own, and it's a particularly wiley bunch. This is just a wrapper to automate running it on a buncha files.

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-imgmin --save-dev

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


The "imgmin" task


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

  imgmin: {
    dist: {
        files: {
          'dest/img.jpg': 'src/img.jpg',
          'dest/img.png': 'src/img.png'

It's pretty darn slow, so I'd be careful about giving it too many files.


In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
