Timing Problems with many files

[benedikt-bartscher]

Grunt is running kinda out of sync if i process many files with uncss and compress.

Example Gruntfile:

module.exports = function(grunt) {
  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
    aws: grunt.file.readJSON('aws-keys.json'),
      uncss: {
        dist: {
	  options: {
            ignore: [
		    '.collapsing',
		    '.collapsed',
	            ],
            ignoreSheets: [/fonts.googleapis/],
            htmlroot: './src',
          },
	  files: [{
            expand: true,
            cwd: 'src/',
            src: ['**/index.html'],
            dest: 'dist/',
	    ext: '.css'
          }]
	}
      },
      compress: {
        options: {
          mode: 'brotli',
          brotli: {
            mode: 1
          }
        },
        css: {
	  files: [
	    {expand: true, cwd: 'dist/', src: ['**/*.css'], dest: 'dist/', extDot: 'last', ext: '.css.br'},
	  ]
        },
      },
  });
  grunt.loadNpmTasks('grunt-uncss');
  grunt.loadNpmTasks('grunt-contrib-compress');
  grunt.registerTask('css', ['uncss', 'compress:css']);
};
