angularjs - Grunt usemin，获取压缩文件的最终路径以允许预加载

问题描述

我有一个这样的 HTML 块用于缩小 css 和 js 文件：

<!-- build:css static/assets/css/combined.css -->
<link rel="stylesheet" href="static/bower_components/font-awesome/css/font-awesome.css">
<link rel="stylesheet" href="static/bower_components/photoswipe/dist/photoswipe.css" />
<link rel="stylesheet" href="static/bower_components/photoswipe/dist/default-skin/default-skin.css" />
<link rel="stylesheet" href="static/assets/css/jasny-bootstrap.min.css">
<link rel="stylesheet" href="static/assets/css/main.min.css">
<link rel="stylesheet" href="static/assets/css/custom.css">
<link rel="stylesheet" href="static/common/da-angular-spinkit/angular-spinkit.min.css">
<!-- endbuild -->

我需要对资源进行预加载，static/assets/css/combined.css但最终文件的名称末尾有一个哈希，所以最终路径类似于static/assets/css/combined.min-af5890ce41.css，所以我不知道如何包含以下标记：

<link rel="preload" href="static/assets/css/combined.min-af5890ce41.css"/>
 -------------------------------------------^^^^^^^^^^^^^^^^^^^^^^^^^^^

因为我不知道生成的缩小文件的最终名称是什么。

我怎样才能得到这个生成文件的输出？我只需要最终的路径名。我搜索grunt-usemin但似乎是“极简主义”。

谢谢你。

如果您可以看到哪个模块正在作用于文件哈希，我在项目中发现了一些 grunt 代码：

/client/static/bower_components/bootstrap/Gruntfile.js：

在这里我可以看到：

jshint
丑化
较少的
csslint
cssmin
csscomb
htmlmin

我看不到这些模块对index.htmlbuild:js或build:cssindex.html 有什么作用。

/client/static/bower_components/photoswipe/Gruntfile.js：

在这里我可以看到 npm 任务：

  grunt.loadNpmTasks('grunt-contrib-clean');
  grunt.loadNpmTasks('grunt-contrib-concat');
  grunt.loadNpmTasks('grunt-contrib-uglify');
  grunt.loadNpmTasks('grunt-contrib-jshint');
  grunt.loadNpmTasks('grunt-contrib-watch');
  grunt.loadNpmTasks('grunt-sass');
  grunt.loadNpmTasks('grunt-autoprefixer');
  grunt.loadNpmTasks('grunt-contrib-copy');
  grunt.loadNpmTasks('grunt-jekyll');
  grunt.loadNpmTasks('grunt-contrib-cssmin');
  grunt.loadNpmTasks('grunt-aws-s3');
  grunt.loadNpmTasks('grunt-svgmin');

在文件夹/dev/中有一个带有此代码的 gruntfile.js（似乎不相关）：

var src = "../src/client/";

module.exports = function (grunt) {
    grunt.loadNpmTasks("grunt-angular-gettext");

    // We extract translations with 'grunt nggettext_extract'. Those files go to '/dev/translations-extract' directory.
    grunt.initConfig({
        nggettext_extract: {
            pot: {
                files: {
                    'translations-extract/template.pot': [src + 'static/common/**/*.html', src + 'static/states/**/*.html', src + 'index.html', src + 'indexMobile.html']
                }
            },
        },
        // We compile those files (*.po) with 'grunt nggettext_compile. The translations.js file goes to /client/static/util/translations/ dir.
        nggettext_compile: {
            all: {
                options: {
                    module: 'alvarez',
                },
                files: {
                    '../src/client/static/common/translations/translations.js': ['translations-extract/*.po']
                }
            },
        },
    })
}

然后，/dev/bower_components/ 有大量的插件，每个插件里面都有它的 gruntfile.js。
