javascript - 如何消除由相对路径引起的重复需求？

Question

使用该grunt-contrib-requirejs任务优化我的 require.js 项目时，由于相对路径，需要多次使用许多脚本。以下是构建期间输出的依赖项列表：

components/requirejs/require.js
.tmp/scripts/../../components/flight/lib/././utils.js
.tmp/scripts/../../components/flight/lib/./././utils.js
.tmp/scripts/../../components/flight/lib/././../tools/debug/../../lib/./utils.js
.tmp/scripts/../../components/flight/lib/././../tools/debug/../../lib/registry.js
.tmp/scripts/../../components/flight/lib/././../tools/debug/../../lib/utils.js
.tmp/scripts/../../components/flight/lib/././../tools/debug/debug.js
.tmp/scripts/../../components/flight/lib/././compose.js
.tmp/scripts/../../components/flight/lib/./advice.js
.tmp/scripts/../../components/flight/lib/./utils.js
.tmp/scripts/../../components/flight/lib/./../tools/debug/../../lib/./utils.js
.tmp/scripts/../../components/flight/lib/./../tools/debug/../../lib/registry.js
.tmp/scripts/../../components/flight/lib/./../tools/debug/../../lib/utils.js
.tmp/scripts/../../components/flight/lib/./../tools/debug/debug.js
.tmp/scripts/../../components/flight/lib/./compose.js
.tmp/scripts/../../components/flight/lib/./registry.js
.tmp/scripts/../../components/flight/lib/component.js

注意如何utils.js包含 7 次：

.tmp/scripts/../../components/flight/lib/./utils.js
.tmp/scripts/../../components/flight/lib/././utils.js
.tmp/scripts/../../components/flight/lib/./././utils.js
.tmp/scripts/../../components/flight/lib/./../tools/debug/../../lib/utils.js
.tmp/scripts/../../components/flight/lib/./../tools/debug/../../lib/./utils.js
.tmp/scripts/../../components/flight/lib/././../tools/debug/../../lib/utils.js
.tmp/scripts/../../components/flight/lib/././../tools/debug/../../lib/./utils.js

Flight需要utils.js在其lib路径中的每个脚本中./util，有时还需要其他依赖项，然后./util再次需要。

grunt-contrib-requirejs将他们的选项直接传递给requirejs，其中包含一个trimDots应该“[修剪] . 和 .. 从路径段数组中的函数。”

为什么不处理一些明显的重复项？

我该怎么做才能消除相对路径等于相同绝对路径的其他重复项？

如果相对路径将规范化为绝对路径，一切都会好的。

更新：

这就是我的项目的结构：

.tmp/scripts/ (where coffeescript is compiled)
app/scripts/ (coffeescript source)
components/ (bower components)
dist/ (where optimized code is output)
Gruntfile.coffee (requirejs config)

这是我的 Gruntfile 中的 requirejs 配置：

requirejs:
  dist:
    options:
      baseUrl: '.tmp/scripts'
      # paths relative to baseUrl
      paths:
        requireLib: '../../components/requirejs/require'
      include: 'requireLib'
      optimize: 'uglify2'
      generateSourceMaps: true
      preserveLicenseComments: false
      useStrict: true
      wrap: true
      name: 'main'
      out: 'dist/main.js'
      mainConfigFile: '.tmp/scripts/main.js'

这是里面的内容app/scripts/main.coffee：

require.config
  paths:
    # required dependencies
    jquery: '../../components/jquery/jquery'
    es5shim: '../../components/es5-shim/es5-shim'
    es5sham: '../../components/es5-shim/es5-sham'
    # plugins
    text: '../../components/requirejs-text/text'
    pickadate: '../../components/pickadate/source/pickadate.legacy'
  map:
    '*':
      'flight/component': '../../components/flight/lib/component'
  shim:
    '../../components/flight/lib/index':
      deps: ['jquery', 'es5shim', 'es5sham']
    'app':
      deps: ['../../components/flight/lib/index']

require ['app'], (App) ->
  App.initialize()

这是里面的内容app/scripts/app.coffee：

define [
  'ui/apple',
  'ui/orange'
], (Apple, Orange) ->
  initialize = ->
    Apple.attachTo document
    Orange.attachTo document
    return

  initialize: initialize

两者app/scripts/ui/apple.coffee和app/scripts/ui/orange.coffee都很简单：

"use strict"
define ['flight/component'], (defineComponent) ->
  apple = ->
    # stuff
  defineComponent apple

尝试在 grunt-contrib-requirejs 选项中设置 baseUrl：

requirejs: {
    compile: {
        options: {
            baseUrl: "path/to/base"
        }
    }
}

记录在这里。

我在您的代码中看到了一些引起问题的东西。我知道这个问题是在三年前提出的，所以其中一些问题在当时可能并不适用。但是我及时回过头来看了三年前的航班代码，然后才回答。

你为什么要提供requireLibgrunt 插件？您不需要这样做，因为 grunt 插件应该加载它自己的。结果将是两个需要加载的库，这令人困惑。
Shim 配置仅适用于非 AMD 模块，但是您正在填充“app”和 flight“index”，它们都是 AMD 模块。我会期待一些奇怪的行为。

为了修复 #2 并使您的代码更简单，您可以完全移除 shim 并简单地映射所有与“飞行”相关的内容：

# main.coffee
require.config
  paths:
    # required dependencies
    jquery: '../../components/jquery/jquery'
    es5shim: '../../components/es5-shim/es5-shim'
    es5sham: '../../components/es5-shim/es5-sham'
    # plugins
    text: '../../components/requirejs-text/text'
    pickadate: '../../components/pickadate/source/pickadate.legacy'
  map
    '*':
      'flight': '../../components/flight/lib'

require ['jquery', 'es5shim', 'es5sham'], (App) ->
  require ['app'], (App) ->
    App.initialize()

# app.coffee
define [
  'flight/index',
  'ui/apple',
  'ui/orange'
], (Apple, Orange) ->
  initialize = ->
    Apple.attachTo document
    Orange.attachTo document
    return

  initialize: initialize

我不确定这是否能解决你的问题，所以如果你可以上传一个带有相关代码的小 zip 文件，那将有很大帮助。
