如何在yeoman/grunt项目中自动包含脚本？

Question

我有一个可用的Yeoman项目。我正在使用grunt-usemin。

为了包含JavaScript，我在index.html中这样做：

<!-- build:js scripts/includes.js -->
<script src="/bower_components/jquery/jquery.min.js"></script>
<script src="/bower_components/underscore/underscore-min.js"></script>
<script src="/bower_components/angular/angular.js"></script>
<script src="/bower_components/angular-route/angular-route.min.js"></script>
<script src="/bower_components/angular-resource/angular-resource.min.js"></script>
<script src="/bower_components/angular-sanitize/angular-sanitize.min.js"></script>
<script src="/bower_components/angular-ui-date/src/date.js"></script>
<script src="/bower_components/angulartics/src/angulartics.js"></script>
<script src="/bower_components/angulartics/src/angulartics-ga.js"></script>
<script src="/bower_components/jquery-ui/ui/jquery-ui.js"></script>
<script src="/assets/vendor/bootstrap.2.3.1.min.js"></script>
... a few more libs like that

<script src="/scripts/config.processed.js"></script>
<script src="/scripts/app.js"></script>

<script src="/scripts/controllers/first_controller.js"></script>
<script src="/scripts/controllers/second_controller.js"></script>
<script src="/scripts/controllers/third_controller.js"></script>
<script src="/scripts/controllers/fourth_controller.js"></script>
<script src="/scripts/controllers/fith_controller.js"></script>
<script src="/scripts/controllers/sixth_controller.js"></script>
<script src="/scripts/controllers/seventh_controller.js"></script>
... 20 more like that

<script src="/scripts/directives/first_directive.js"></script>
<script src="/scripts/directives/second_directive.js"></script>
<script src="/scripts/directives/third_directive.js"></script>
... 10 more like that

<script src="/scripts/services/first_service.js"></script>
<script src="/scripts/services/second_service.js"></script>
...

<script src="/scripts/filters/first_filter.js"></script>
<script src="/scripts/filters/second_filter.js"></script>
...
<!-- endbuild -->

这段文字很啰嗦。我希望能够像这样做:

在 index.html 文件中:

<!-- build:js scripts/includes.js -->

<!-- library includes as before -->
<script src="/bower_components/jquery/jquery.min.js"></script> 
<script src="/bower_components/underscore/underscore-min.js"></script>
...

<!-- Replace application includes with this: -->
<script src="<% '/scripts/**/*.js' %>"></script>

<!-- endbuild -->

我使用了grunt-include-source

安装它：

npm install grunt-include-source --save-dev

在 Gruntfile 文件中：

在 initConfig 之前加载它：

module.exports = function (grunt) {
  ...
  grunt.loadNpmTasks('grunt-include-source');

在initConfig中配置includeSource本身：

grunt.initConfig({
  ...,
  includeSource: {
      options: {
        basePath: 'app',
        baseUrl: '/',
      },
      server: {
        files: {
          '.tmp/index.html': '<%= yeoman.app %>/index.html'
        }
      },
      dist: {
        files: {
          '<%= yeoman.dist %>/index.html': '<%= yeoman.app %>/index.html'
        }
      }
    }

将此任务添加到您想要的位置（这里，我将其添加到构建任务中）：

grunt.registerTask('build', [
    'clean:dist',
    'includeSource:dist',
    'useminPrepare',
    ...

将其添加到监视任务中：

watch: {
  ...,
  includeSource: {
    files: ['<%= yeoman.app %>/index.html'],
    tasks: ['includeSource:server']
  }

修改 useminPrepare （如果您使用 yeoman）

useminPrepare: {
  // changed from app to dist, to take index.html processed by includeSource in dist
  html: '<%= yeoman.dist %>/index.html',
  options: {
    dest: '<%= yeoman.dist %>'
  }
},

我曾经使用了两个子任务：dist和server来在不同的目录中生成index.html。

编辑：如何将你的javascript包含在index.html中：

<!-- build:js({.tmp,dist,app}) /scripts/application.js -->
<!-- vendor, external -->
<script src="/bower_components/jquery/jquery.min.js"></script>
<script src="/bower_components/underscore/underscore-min.js"></script>
<script src="/assets/vendor/underscore.extentions.js"></script>
<script src="/bower_components/angular/angular.js"></script>
<script src="/bower_components/select2/select2.js"></script>
<script src="/bower_components/angular-ui-select2/src/select2.js"></script>

<!-- entry point -->
<script src="/scripts/config.processed.js"></script>
<script src="/scripts/app.js"></script>

<!--include everything in scripts/ except files directly inside scripts (without subdirectory) -->
<!-- include: "type": "js", "files": ["scripts/**/*.js", "!scripts/*.js"] -->

<!-- endbuild -->

如果您想包含所有脚本，请执行以下操作：

<!-- include: "type": "js", "files": "scripts/**/*.js" -->

你的HTML索引文件是什么样子的？我按照所有步骤操作了，但是因为不知道HTML注释标签，所以无法使其正常工作。谢谢！ - DanFritz

我正在使用带有Angular和Ionic/Cordova的Yeoman，对于这个例子（它可以工作，谢谢！），你需要将/www视为分发文件夹。例如，includeSource：dist应该指向www/index.html。 - FugueWeb

另外，我的Grunt文件有require('load-grunt-tasks')(grunt);，所以我不需要使用loadNpmTasks()。 - FugueWeb

或者，您可以使用 grunt serve 在相同的目录中创建文件（覆盖现有文件），并将其配置为在“build”时加载到www。 - FugueWeb

谢谢。我不能不说这似乎过于复杂了，但这并不是你的错。 - Casey
