One advantage that the aforementioned copy-webpack-plugin brings that hasn't been explained before is that all the other methods mentioned here still bundle the resources into your bundle files (and require you to "require" or "import" them somewhere). If I just want to move some images around or some template partials, I don't want to clutter up my javascript bundle file with useless references to them, I just want the files emitted in the right place. I haven't found any other way to do this in webpack. Admittedly it's not what webpack originally was designed for, but it's definitely a current use case. (@BreakDS I hope this answers your question - it's only a benefit if you want it)

在我的例子中，我使用webpack作为wordpress插件来压缩js文件，其中插件文件已经被压缩了，需要跳过这个过程。

optimization: {
    minimize: false,
},
externals: {
    "jquery": "jQuery",
},
entry: glob.sync('./js/plugin/**.js').reduce(function (obj, el) {
    obj[path.parse(el).name] = el;
    return obj
}, {}),
output: {
    path: path.resolve(__dirname, './js/dist/plugin'),
    filename: "[name].js",
    clean: true,
},

用于将js文件复制到build文件夹。使用任何其他方法，如文件加载器和复制webpack都会产生问题。

希望它能帮助到一些人。

webpack配置文件(在webpack 2中)允许你导出承诺链，只要最后一步返回一个webpack配置对象。参见承诺配置文档。从这里开始:

webpack现在支持从配置文件中返回Promise。这允许在配置文件中进行异步处理。

你可以创建一个简单的递归复制函数来复制你的文件，并且只在触发webpack之后。例如:

module.exports = function(){
    return copyTheFiles( inpath, outpath).then( result => {
        return { entry: "..." } // Etc etc
    } )
}

你不需要到处复制东西，webpack的工作方式与gulp不同。Webpack是一个模块捆绑器，你在文件中引用的所有内容都将被包括在内。你只需要为此指定一个加载器。

所以如果你写:

var myImage = require("./static/myImage.jpg");

Webpack将首先尝试将引用的文件解析为JavaScript(因为这是默认的)。当然，这将会失败。这就是为什么您需要为该文件类型指定一个加载器。例如，文件或url加载器获取引用的文件，将其放入webpack的输出文件夹(在您的情况下应该是构建的)，并返回该文件的散列url。

var myImage = require("./static/myImage.jpg");
console.log(myImage); // '/build/12as7f9asfasgasg.jpg'

通常加载器是通过webpack配置来应用的:

// webpack.config.js

module.exports = {
    ...
    module: {
        loaders: [
            { test: /\.(jpe?g|gif|png|svg|woff|ttf|wav|mp3)$/, loader: "file" }
        ]
    }
};

当然，您需要首先安装文件加载器才能使其工作。

我加载静态图像和字体的方式:

module: {
    rules: [
      ....

      {
        test: /\.(jpe?g|png|gif|svg)$/i,
        /* Exclude fonts while working with images, e.g. .svg can be both image or font. */
        exclude: path.resolve(__dirname, '../src/assets/fonts'),
        use: [{
          loader: 'file-loader',
          options: {
            name: '[name].[ext]',
            outputPath: 'images/'
          }
        }]
      },
      {
        test: /\.(woff(2)?|ttf|eot|svg|otf)(\?v=\d+\.\d+\.\d+)?$/,
        /* Exclude images while working with fonts, e.g. .svg can be both image or font. */
        exclude: path.resolve(__dirname, '../src/assets/images'),
        use: [{
          loader: 'file-loader',
          options: {
            name: '[name].[ext]',
            outputPath: 'fonts/'
          },
        }
    ]
}

不要忘记安装文件加载器来让它工作。

让我们说你所有的静态资产都在一个文件夹“静态”在根级别，你想复制他们到构建文件夹维护子文件夹的结构，然后 在你的参赛档案中)

//index.js or index.jsx

require.context("!!file?name=[path][name].[ext]&context=./static!../static/", true, /^\.\/.*\.*/);
