让 Webpack 不捆绑文件

Question

所以现在我正在使用一个原型，我们正在使用 webpack（用于构建 .tsx 文件和复制 .html 文件）和 webpack-dev-server 之间的组合用于开发服务。你可以假设我们也使用 React 和 ReactDOM 作为两个库依赖项。我们当前的构建输出是以下结构：

dist
    -favicon.ico
    -index.html
    -main.js
    -main.js.map // for source-mapping between tsx / js files

这会将所有模块（包括库依赖项放入大捆绑文件中）。我希望最终结果如下所示：

dist
    -favicon.ico
    -index.html
    -appName.js
    -appName.min.js
    -react.js
    -react.min.js
    -reactDOM.js
    -reactDOM.min.js

我在 index.html 和 .tsx 文件中的 import 语句中引用了每个库。所以我的问题是这个... 如何从 webpack 生成这个巨大的捆绑 .js 文件到单个 .js 文件（包括库，无需单独指定每个文件）？ **奖励：我知道如何做 prod/dev 环境标志，那么我如何缩小这些单独的文件（同样不捆绑它们）？

当前 webpack.config：

var webpack = require("webpack"); // Assigning node package of webpack dependency to var for later utilization
var path = require("path"); // // Assigning node package of path dependency to var for later utilization

module.exports = {
    entry:  [
                "./wwwroot/app/appName.tsx", // Starting point of linking/compiling Typescript and dependencies, will need to add separate entry points in case of not deving SPA
                "./wwwroot/index.html", // Starting point of including HTML and dependencies, will need to add separate entry points in case of not deving SPA
                "./wwwroot/favicon.ico" // Input location for favicon
            ],
    output: {
        path: "./dist/", // Where we want to host files in local file directory structure
        publicPath: "/", // Where we want files to appear in hosting (eventual resolution to: https://localhost:4444/)
        filename: "appName.js" // What we want end compiled app JS file to be called
    },

    // Enable sourcemaps for debugging webpack's output.
    devtool: "source-map",

    devServer: {
        contentBase: './dist', // Copy and serve files from dist folder
        port: 4444, // Host on localhost port 4444
        // https: true, // Enable self-signed https/ssl cert debugging
        colors: true // Enable color-coding for debugging (VS Code does not currently emit colors, so none will be present there)
    },

    resolve: {
        // Add '.ts' and '.tsx' as resolvable extensions.
        extensions: [
            "",
            ".ico",
            ".js",
            ".ts",
            ".tsx",
            ".web.js",
            ".webpack.js"
        ]
    },

    module: {
        loaders: [
            // This loader copies the index.html file & favicon.ico to the output directory.
            {
                test: /\.(html|ico)$/,
                loader: 'file?name=[name].[ext]'
            },
            // All files with a '.ts' or '.tsx' extension will be handled by 'ts-loader'.
            {
                test: /\.tsx?$/,
                loaders: ["ts-loader"]
            }
        ],

        preLoaders: [
            // All output '.js' files will have any sourcemaps re-processed by 'source-map-loader'.
            {
                test: /\.js$/,
                loader: "source-map-loader"
            }
        ]
    },

    // When importing a module whose path matches one of the following, just
    // assume a corresponding global variable exists and use that instead.
    // This is important because it allows us to avoid bundling all of our
    // dependencies, which allows browsers to cache those libraries between builds.
    // externals: {
    //     "react": "React",
    //     "react-dom": "ReactDOM",
    //     "redux": "Redux"
    // }
};

将output 设置更改为名称驱动，例如

    entry: {
        dash: 'app/dash.ts',
        home: 'app/home.ts',
    },
    output: {
        path: './public',
        filename: 'build/[name].js',
        sourceMapFilename: 'build/[name].js.map'
    },

要扩展@basarat 的答案，您可以使用节点标准库中的glob 包来构建“入口”配置：

const glob = require("glob");

module.exports = [
  {
    target: "node",
    entry: glob.sync("./src/**/*.test.{ts,tsx}").reduce((acc, file) => {
      acc[file.replace(/^\.\/src\//, "")] = file;
      return acc;
    }, {}),
    output: {
      filename: "[name].js",
      chunkFilename: "[name]-[id].js",
      path: __dirname + "/dist"
    },
    //...
  }
];

这会构建与其源名称相同的文件，将.ts 和.tsx 替换为.js。

Answer 3

从问题中复制的 OP 答案

最终找到了适合我需求的解决方案，尽管再次以 webpack-y 方式，需要一些额外的配置。仍然想让它更有活力，但会在稍后的时间点完善它。我正在寻找的解决方案是“分块”公共模块的能力，但我将其声明为给定 webpack 中提供的“入口”点的文件名。我不介意一些文件被合并，这是有意义的，但考虑到项目不是 SPA（单页应用程序），我希望整个文件处于组件级别。

附加代码最终是：

plugins: [
    new webpack.optimize.CommonsChunkPlugin({ // This plugin is for extracting and created "chunks" (extracted parts of the code that are common and aren't page specific)
        // One of these instances of plugins needs to be specified for EACH chunk file output desired
        filename: "common.js", // Filename for this particular set of chunks to be stored
        name: "common", // Entry point name given for where to pull all of the chunks
        minChunks: 3 // Minimum number of chunks to be created
    })
]

我还必须通过变量名参数化入口点（例如见下文），以便我可以将 react、react-dom 和 redux 模块分配给 common.js 文件。

entry:  {
    main:    "./wwwroot/app/appName.tsx", // Starting point of linking/compiling Typescript and dependencies, will need to add separate entry points in case of not deving SPA
    index:   "./wwwroot/index.html", // Starting point of including HTML and dependencies, will need to add separate entry points in case of not deving SPA
    favicon: "./wwwroot/favicon.ico", // Input location for favicon
    common:  [ "react", "react-dom", "redux" ] // All of the "chunks" to extract and place in common file for faster loading of common libraries between pages
},
