A Grunt plugin to find only the used images in your CSS and HTML files and copy those images to your build location.

This plugin requires Grunt.

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-img-find-and-copy --save-dev

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

grunt.loadNpmTasks('grunt-img-find-and-copy');

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

grunt.initConfig({
  img_find_and_copy: {
        resources: {
          files: {
            'build': ['css/**/*.css', '*.html']
          }
        }
      }
})

The options are pretty simple, in the example above 'build': ['css/**/*.css', '*.html'] the build is the location folder where you want your images copied to, this is ideally your build folder (e.g. dist etc). The array of wildcard file definitions in ['css/**/*.css', '*.html'] are the files that will be evaluated for image references.

You can specify CSS or HTML files, once images are found they will be copied to the build folder and the relative paths will be mapped and resolved so all original paths remain the same.

Evaluate all my local CSS and HTML files that are used in Dev mode and copy all the referenced images to my build folder. So I can have 100s of reference images in Dev mode (if needed) but only have the used actually used by my app to appear in my final build.

grunt.initConfig({
  img_find_and_copy: {
        resources: {
          files: {
            'build': ['css/**/*.css', '*.html']
          }
        }
      }
})

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.

• 1.0.1 - If no build folder found, it now gives a console error.
• 1.0.0 - Initial version (bugs may be found so please test and raise any issues).
