Usage Examples

default config

  assets: {
    files: {
      'path/to/target.php': ['path/to/style.css', 'path/to/scripts.js']

This example task will copy path/to/style.css to assets/css/{md5hash}.style.css and path/to/scripts.js to path/to/{md5hash}.scripts.js and update assets reference in path/to/target.php.

Custom config

  options: {
      algorithm: 'sha1',
      length: 4,
      format: false,
      rename: true,
      manifest: 'assets/manifest.json',
    files: {
      'scripts.php': ['assets/css/main.min.css', 'assets/js/scripts.min.js']

This example task will rename assets/css/main.min.css to assets/css/main.{sha1hash}.min.css and assets/js/scripts.min.js to assets/js/scripts.{sha1hash}.min.js and update assets reference in scripts.php. Also generate assets summary at assets/manifest.json.
