Image optimization for Grunt using imgo

Installation

This plugin requires Grunt 0.4.

Install imgo (see How to install imgo on OS X below for instructions).

npm install grunt-imgo --save-dev

Add to your Gruntfile.js:

grunt.loadNpmTasks('grunt-imgo');

Then add section named imgo inside grunt.initConfig(). See next section for details.

Parameters

src string|array

Images list: PNG, GIF or JPEG. String or array. Wildcards are supported.

dest string

Destination path for images copying before optimizing.

icons: {
  src: 'static/dev/img/*.*',
  dest: 'static/build/img/'
}

options string

Any options you want to pass to imgo.

skip boolean

If true task will not be ran. In example, you can skip imgo on Windows (becase of difficult installation):

skip: require('os').platform() === 'win32'

Gruntfile Example

module.exports = function(grunt) {
	grunt.initConfig({
		imgo: {
		  icons: {
		    src: 'icons/*.png'
		  }
		}
	});
	grunt.loadNpmTasks('grunt-imgo');
	grunt.registerTask('default', ['imgo']);
};
