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
    } )
}

你可以在package.json中编写bash:

# package.json
{
  "name": ...,
  "version": ...,
  "scripts": {
    "build": "NODE_ENV=production npm run webpack && cp -v <this> <that> && echo ok",
    ...
  }
}

如果你想复制静态文件，你可以这样使用文件加载器:

对于HTML文件:

在webpack.config.js中:

module.exports = {
    ...
    module: {
        loaders: [
            { test: /\.(html)$/,
              loader: "file?name=[path][name].[ext]&context=./app/static"
            }
        ]
    }
};

在js文件中:

  require.context("./static/", true, /^\.\/.*\.html/);

./static/相对于js文件的位置。

你可以对图像或其他东西做同样的事情。 语境是一种强大的探索方法!!

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)

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。

使用文件加载器模块要求资产是webpack的使用方式(源代码)。然而，如果你需要更大的灵活性或想要一个更干净的界面，你也可以直接使用我的copy-webpack-plugin (npm, Github)复制静态文件。对于静态构建示例:

const CopyWebpackPlugin = require('copy-webpack-plugin');
 
module.exports = {
    context: path.join(__dirname, 'your-app'),
    plugins: [
        new CopyWebpackPlugin({
            patterns: [
                { from: 'static' }
            ]
        })
    ]
};

兼容性注意:如果你使用的是旧版本的webpack，比如webpack@4.x.x，请使用copy-webpack-plugin@6.x.x。否则使用最新的。
