我正在为我的项目整合一个新的webpack构建，它实际上工作得很好。我有一个问题，我想得到一些帮助，如果有人有一个想法。我必须从我的工作电脑重新输入所有这些，所以请原谅任何错别字。

Package.json

{
    "name": "test_webpack",
    "version": "1.0.0",
    "description": "",
    "main": "index.js",
    scripts: {
        "build": "webpack --config webpack.production.js"
        "dev": "webpack serve --config webpack.development.js"
    },
    "devDependencies": {
        "@babel/core": "^7.22.9",
        "@babel/preset-env": "^7.22.9",
        "babel-loader": "^9.1.3",
        "css-loader": "^6.8.1",
        "html-webpack-plugin": "^5.5.3",
        "mini-css-extract-plugin": "^2.7.6",
        "sass": "^1.64.1",
        "sass-loader": "^13.3.2",
        "style-loader": "^3.3.3",
        "webpack": "^5.88.2",
        "webpack-cli": "^5.1.4",
        "webpack-dev-server": "^4.15.1"
    }
}

字符串

webpack.production.js

const path = reqire('path');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');

module.exports = {
    mode: "production",
    entry: {
        "script.min": path.resolve(_dirname, 'src/js/index.js'),
        "search": path.resolve(_dirname, 'src/js/functional/modules.js'),
        "modules/carousel": path.resolve(_dirname, 'src/js/modules/carousel.js'),

    },
    output: {
        path: path.resolve(__dirname, 'dist'),
        filename: '[name].js',
        clean: true,
        assetModuleFilename: '[name].[ext]'
    },
    module: {
        rules: [
            {
                est:/\.scss$/i,
                use: [
                    MiniCssExtractPlugin.loader, 
                    {
                        loader:'css-loader',
                        options: {url: false}
                    },
                    {loader: 'sass-loader'}
                ]
            },
            {
                test:/\.js$/,
                exclude:/node_modules/,
                use: {
                    loader: 'babel-loader',
                    options: {
                        presets: ['@babel/preset-env']
                    }
                }
            },
            {
                test:/\.(png|svg|jpg|jpeg|gif)$/i,
                type: 'asset/resource'
            }
        ]
    },
    plugins: [
        new MiniCssExtractPlugin({
            filename: "shared.min.css"
       })
    ]
}

问题是否有一种方法，我可以取代这个......与动态的东西？：

"modules/carousel": path.resolve(_dirname, 'src/js/modules/carousel.js'),
        "modules/handleEmoji": path.resolve(_dirname, 'src/js/modules/handleEmoji.js'),
        "modules/modalAccordion": path.resolve(_dirname, 'src/js/modules/modalAccordion.js'),
        "modules/sliders": path.resolve(_dirname, 'src/js/modules/sliders.js'),
        "modules/tourVideo": path.resolve(_dirname, 'src/js/modules/tourVideo.js'),
        "modules/vectorSwap": path.resolve(_dirname, 'src/js/modules/vectorSwap.js')

这样，我的modules文件夹中的每个文件都将被单独编译和输出。我想出了如何把它们都捆绑在一起，但我需要把它们分开。现在，每次我们添加一个模块，我们都必须将其添加到webpack配置文件中。现在它输出到“dist”文件夹中的“modules”文件夹。

似乎entry选项也可以接受一个返回promise的函数：

{
    /**
     * The entry point(s) of the compilation.
     */
    entry: EntryNormalized;
    /**
}

个字符
在该函数中，您可以读取modules目录中的文件，并相应地生成entry对象。

您可以创建一个模块名称数组，然后使用Array.reduce（）创建一个具有入口点的对象。

const path = require('path');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');

const modules = [
  'carousel',
  'handleEmoji',
  'modalAccordion',
  'sliders',
  'tourVideo',
  'vectorSwap',
];

const entryPoints = modules.reduce((entries, module) => {
  entries[`modules/${module}`] = path.resolve(__dirname, `src/js/modules/${module}.js`);
  return entries;
}, {});

module.exports = {
  mode: 'production',
  entry: {
    'script.min': path.resolve(__dirname, 'src/js/index.js'),
    'search': path.resolve(__dirname, 'src/js/functional/modules.js'),
    ...entryPoints, // Spread the dynamically generated entry points
  },
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: '[name].js',
    clean: true,
    assetModuleFilename: '[name].[ext]',
  },
  // Rest of the configuration remains unchanged
};

字符串
生成的entryPoints对象将如下所示：

{
  "modules/carousel": "/full/path/to/src/js/modules/carousel.js",
  "modules/handleEmoji": "/full/path/to/src/js/modules/handleEmoji.js",
  "modules/modalAccordion": "/full/path/to/src/js/modules/modalAccordion.js",
  "modules/sliders": "/full/path/to/src/js/modules/sliders.js",
  "modules/tourVideo": "/full/path/to/src/js/modules/tourVideo.js",
  "modules/vectorSwap": "/full/path/to/src/js/modules/vectorSwap.js"
}

这样，您就不必手动重复相同的入口点，并且构建配置变得更具可伸缩性。
