Webpack构建优化实战

// webpack.config.js
module.exports = {
  cache: {
    type: 'filesystem',
    buildDependencies: {
      config: [__filename]
    }
  },
  optimization: {
    runtimeChunk: 'single',
    splitChunks: {
      chunks: 'all',
      maxInitialRequests: Infinity,
      minSize: 0,
      cacheGroups: {
        vendor: {
          test: /[\\/]node_modules[\\/]/,
          name(module) {
            const packageName = module.context.match(/[\\/]node_modules[\\/](.*?)([\\/]|$)/)[1];
            return `npm.${packageName.replace('@', '')}`;
          }
        }
      }
    }
