使用webpack服务静态资产

我正在尝试从webpack提供静态资产,但是现在正在使用copywebpack插件将任何所需的静态资产复制到我的static_dist /目录中,这也是我的构建文件所在的目录。尽管此技巧有效,但我现在现在还需要提供在构建过程之后生成的stats.json文件。我无法破解并使用copywebpackplugin,因为在运行copywebpackplugin时此文件尚不存在。所有webpacks配置选项都让我有点不知所措,而且似乎无法为这些静态文件提供服务。

//我的webpack.config.js

const PATHS = {
    app: path.join(__dirname, '../src/static'),
    build: path.join(__dirname, '../src/static_dist')
};

const basePath = path.resolve(__dirname, '../src/static/');

module.exports = {
    mode: 'development',
    devtool: 'cheap-module-eval-source-map',
    output: {
        filename: '[name].js',
        path: PATHS.build,
        publicPath: '/static/'
    },
    devServer: {
        watchOptions: {
            aggregateTimeout: 300,
            ignored: /node_modules/,
            poll: 1000,
        },
        port: 3000,
        contentBase: '/static/',
        host: '0.0.0.0',
        disableHostCheck: true,
        historyApiFallback: { index: '/static/index.html' },
        public: 'localhost:8000',
        writeToDisk: true,
       // hot: true
    },
    plugins: [
          new CopyPlugin([
          { from: '../static/assets/img/favicons', to: '../static_dist/favicons' },

          { from: '../static/assets/img/logos', to: '../static_dist/logos' },
          { from: '../static/assets/img/icons', to: '../static_dist/icons'},
        ]),
        new BundleTracker({ path: PATHS.build, filename: './stats/webpack-stats.json'})
    ],
}

现在,可以在domain.com/static/app.[some-hash].js处访问我的广告包,例如,可以在domain.com/static/logos/somelogo.png处访问徽标。看来大多数人没有从同一目录提供这些服务,但是我并不特别在意从何处提供这些服务。只是我可以提供构建后生成的统计文件。

因此,您必须等到webpack编译完成。您可以使用webpack compiler-hook编写自己的插件。这是一个示例脚本。取消测试!

compiler-hook aftercompile

// fs-extra to copy files (npm install fs-extra)
const fs = require('fs-extra');
const path = require('path');

// own plugin: do what ever 
class MyPlugin {
    apply(compiler) {
        compiler.hooks.afterCompile.tap('MyPlugin', (compilation) => {
            // copy all files and folder (recursive)
            fs.copySync(path.resolve(process.cwd(), 'static/assets/img/favicons'), path.resolve(process.cwd(), 'static_dist/favicons'), { recursive: true })
            // return true to emit the output, otherwise false
            return true;
        });
    }
};

//...

// append your plugin to webpacks plugin section
plugins: [
    //...
    new MyPlugin(),
    //...
]
