Webpack 4 - 创建供应商块 [英] Webpack 4 - create vendor chunk

问题描述

在 webpack 3 配置中，我将使用以下代码创建单独的 vendor.js 块:

In a webpack 3 configuration I would use the code below to create separate vendor.js chunk:

entry: {
    client: ['./client.js'],
    vendor: ['babel-polyfill', 'react', 'react-dom', 'redux'],
},

output: {
  filename: '[name].[chunkhash].bundle.js',
  path: '../dist',
  chunkFilename: '[name].[chunkhash].bundle.js',
  publicPath: '/',
},

plugins: [
    new webpack.HashedModuleIdsPlugin(),
    new webpack.optimize.CommonsChunkPlugin({
      name: 'vendor',
    }),
    new webpack.optimize.CommonsChunkPlugin({
      name: 'runtime',
    }),
],

我不知道如何使用 Webpack 4 进行所有更改.我知道 CommonChunksPlugin 已被删除，因此有一种不同的方法可以实现.我还阅读了本教程，但我仍然不确定如何提取运行时块并正确定义输出 属性.

With all the changes I'm not sure how to do it with Webpack 4. I know that CommonChunksPlugin was removed, so there is a different way to achieve that. I've also read this tutorial but I'm still not sure about extracting runtime chunk and properly defining output property.

推荐答案

为了减少供应商 JS 包的大小.我们可以将节点模块包拆分为不同的捆绑文件.我提到了这个 博客 用于拆分 Webpack 生成的庞大的 vendor 文件.我最初使用的那个链接的要点:

In order to reduce the vendor JS bundle size. We can split the node module packages into different bundle files. I referred this blog for splitting the bulky vendor file generated by Webpack. Gist of that link which I used initially:

optimization: {
  runtimeChunk: 'single',
  splitChunks: {
    chunks: 'all',
    maxInitialRequests: Infinity,
    minSize: 0,
    cacheGroups: {
      vendor: {
        test: /[\/]node_modules[\/]/,
        name(module) {
          // get the name. E.g. node_modules/packageName/not/this/part.js
          // or node_modules/packageName
          const packageName = module.context.match(/[\/]node_modules[\/](.*?)([\/]|$)/)[1];

          // npm package names are URL-safe, but some servers don't like @ symbols
          return `npm.${packageName.replace('@', '')}`;
        },
      },
    },
  },
}

如果您想将多个包分组并分块到不同的包中，请参考以下要点.

If one wants to group multiple packages and chunk then into different bundles then refer following gist.

optimization: {
  runtimeChunk: 'single',
  splitChunks: {
    chunks: 'all',
    maxInitialRequests: Infinity,
    minSize: 0,
    cacheGroups: {
      reactVendor: {
        test: /[\/]node_modules[\/](react|react-dom)[\/]/,
        name: "reactvendor"
      },
      utilityVendor: {
        test: /[\/]node_modules[\/](lodash|moment|moment-timezone)[\/]/,
        name: "utilityVendor"
      },
      bootstrapVendor: {
        test: /[\/]node_modules[\/](react-bootstrap)[\/]/,
        name: "bootstrapVendor"
      },
      vendor: {
        test: /[\/]node_modules[\/](!react-bootstrap)(!lodash)(!moment)(!moment-timezone)[\/]/,
        name: "vendor"
      },
    },
  },
}
