npm install grunt-feo --save-dev

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


The 'feo' task


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

  feo: {
    options: {
      'js' : {
        'compressor' : 'yui-js',
        'root' : 'examples/src'
      'backgroundImage' : {
        'base64' : true
      'css' : {
        'compressor' : 'yui-css',
        'root' : 'examples/src'
      'image' : {
        'base64' : true,
        'root' : 'examples/src'
      'logLevel' : 1
    example: {
      'example/src': ['example/dist']

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.
