Question

我正在尝试将使用RequireJS的应用程序迁移到Webpack，并且现有模块存在问题。

以下是应用程序的文件夹结构：

App
--js
----custom
----lib
----app.build.js
----config.js
----app-loader.coffee

lib 和自定义文件夹包含不同的模块

app.build.js 文件：

({
    appDir: ".",
    baseUrl: ".",
    dir: "../build",
    findNestedDependencies: true,
    mainConfigFile: 'config.js',
    modules: [
        {
            name: "app-loader",
            include: ["domReady"]
        }
    ],
    optimize: "uglify",
    optimizeCss: "none",
    pragmas: {
        logExclude: true
    }
});

config.js ：

(function () {
  require.config({
    paths: {
      'bootstrap': 'lib/bootstrap/dist/js/bootstrap',
      'domReady': 'lib/domReady/domReady',
      'jquery': 'lib/jquery/jquery.min',
      'jquery-bbq': 'lib/jquery-bbq/jquery.ba-bbq.min',
      'jquery.browser': 'lib/jquery.browser/dist/jquery.browser',
      'jquery.chosen': 'lib/chosen/chosen.jquery.min',
      'jquery.cookie': 'lib/jquery.cookie/jquery.cookie',
      'jquery.colorpicker': 'lib/jQuery-ColorPicker/colorpicker.min',
      'jquery.fileupload': 'lib/blueimp-file-upload/js/jquery.fileupload',
      'jquery-mobile': 'lib/jquery-mobile-bower/js/jquery.mobile-1.3.2.min',
      'jquery.scrollTo': 'lib/jquery.scrollTo/jquery.scrollTo.min',
      'jquery.tagsinput': 'lib/jquery.tagsinput/src/jquery.tagsinput',
      'jquery.tablednd': 'lib/TableDnD/js/jquery.tablednd',
      'jquery.ui': 'lib/jquery-ui/jquery-ui',
      'jquery.ui.widget': 'lib/blueimp-file-upload/js/vendor/jquery.ui.widget',
      'jquery.validate': 'lib/jquery-validation/dist/jquery.validate',
      'json2': 'lib/JSON-js/json2',
      'swfobject': 'lib/swfobject/swfobject/swfobject',
      'sugar': 'lib/sugar/release/sugar.min',
      'underscore': 'lib/underscore/underscore-min'
    },
    packages: [

    ],
    shim: {
      "bootstrap": { "deps": ['jquery'] },
      'jquery-bbq': {
        deps: ['jquery.browser']
      },
      'jquery.cookie': {
        deps: ['jquery'],
        exports: 'jquery.cookie'
      },
      'jquery.colorpicker': {
        deps: ['jquery']
      },
      'jquery.tablednd': {
        deps: ['jquery']
      },
      'json2': {
        deps: ['jquery'],
        exports: 'JSON'
      },
      'swfobject': {
        exports: 'swfobject'
      },
      'underscore': {
        exports: '_'
      }
    }
  });

}).call(this);

app-loader.coffee ：

equire ['config'], ->
  require ['jquery.ui', 'jquery.validate'], ->

    _appDeveloper?()

    require [
      'custom/application/footer'
      'custom/application/floatingwindow'
      'custom/application/join'
      'custom/application/login'
      'custom/application/main'
      'custom/application/menu'
      'custom/application/message'      
      'custom/application/topmenu'      
      ]

我的 webpack.config.js ：

var webpack = require('webpack'),
    path = require('path'),
    glob = require('glob');

var config = {
    context: __dirname + 'App/js',
    entry: {
        app: 'app-loader.coffee'
    },
    output: {
        path: __dirname + '/public/js',
        filename: '[name].js',
        chunkFilename: '[id].[name].js'
    },
    plugins: [
        new webpack.ProvidePlugin({
            _: 'underscore',
            $: 'jquery'
        })
    ],
    module: {
        loaders: [
            {test: /bootstrap/, loader: 'imports?jquery'},
            {test: /jquery-bbq/, loader: 'imports?jquery.browser'},
            {test: /jquery.cookie/, loader: 'exports?jquery.cookie!imports?jquery'},
            {test: /jquery.colorpicker/, loader: 'imports?jquery'},
            {test: /jquery.tablednd/, loader: 'imports?jquery'},
            {test: /json2/, loader: 'exports?JSON!imports?jquery'},
            {test: /swfobject/, loader: 'exports?swfobject'},
            {test: /\.coffee$/, loader: 'coffee-loader'}
        ]
    },
    resolve: {
        extensions: ['', '.coffee', '.js'],
        root: [__dirname + '/App/js'],
        alias: {
            'bootstrap': 'lib/bootstrap/dist/js/bootstrap',
            'domReady': 'lib/domReady/domReady',
            'jquery': 'lib/jquery/jquery.min',
            'jquery-bbq': 'lib/jquery-bbq/jquery.ba-bbq.min',
            'jquery.browser': 'lib/jquery.browser/dist/jquery.browser',
            'jquery.chosen': 'lib/chosen/chosen.jquery.min',
            'jquery.cookie': 'lib/jquery.cookie/jquery.cookie',
            'jquery.colorpicker': 'lib/jQuery-ColorPicker/colorpicker.min',
            'jquery.fileupload': 'lib/blueimp-file-upload/js/jquery.fileupload',
            'jquery-mobile': 'lib/jquery-mobile-bower/js/jquery.mobile-1.3.2.min',
            'jquery.scrollTo': 'lib/jquery.scrollTo/jquery.scrollTo.min',
            'jquery.tagsinput': 'lib/jquery.tagsinput/src/jquery.tagsinput',
            'jquery.tablednd': 'lib/TableDnD/js/jquery.tablednd',
            'jquery.ui': 'lib/jquery-ui/jquery-ui',
            'jquery.ui.widget': 'lib/blueimp-file-upload/js/vendor/jquery.ui.widget',

            'swfobject': 'lib/swfobject/swfobject/swfobject',
            'sugar': 'lib/sugar/release/sugar.min',
            'underscore': 'lib/underscore/underscore-min'
        }
    },
    resolveLoader: {
        root: path.join(__dirname, 'node_modules')
    }
};

module.exports = config;

我一跑webpack，就会收到以下错误消息：

ERROR in /Users/user/project/App/js/app-loader.coffee
Module not found: Error: Cannot resolve module 'jquery
validation/dist/jquery.validate' in /Users/user/project/App/js
@ /Users/user/project/App/js/app-loader.coffee 2:9-7:4

validation/dist/jquery.validate' in

不确定我在webpack的配置文件中还缺少什么......

根据@Tom Chen的评论，我能够进一步深入了解我的配置并通过添加Node和＆＃39; Bower＆＃39;来解决它。配置文件的resolve.modulesDirectories部分中的模块。

以下是我的 Webpack.config.js 文件：

    path = require('path'),
    ExtractTextPlugin = require('extract-text-webpack-plugin');

    $: 'jquery',
    jQuery: 'jquery',

  }),
  new ExtractTextPlugin(__dirname + '/Content/css/[name].css'),
  new webpack.optimize.CommonsChunkPlugin(
    /* chunkName= */"vendor", /* filename= */"vendor.js"
  ),
  new webpack.optimize.LimitChunkCountPlugin({
    maxChunks: 1
  })

if (process.env.NODE_ENV === 'production') {
  var optPlugins = [
    new webpack.optimize.DedupePlugin(),
    new webpack.optimize.UglifyJsPlugin({

Answer 2

从webpack的错误消息中，我相信你错过了一些依赖项。将这些内容添加到resolve.alias对象可能会有所帮助：

'jqueryvalidation/dist/jquery.validate', 'jquery-ui/jquery-ui',

迁移现有的RequireJS应用程序以使用Webpack
