2021-04-29 npm run build 打出来的JS过大 分包代码

在vue.config.js 中添加

configureWebpack: config => {

  if (process.env.NODE_ENV === 'production') {

    config.mode = 'production';

    config["performance"] = {//打包文件大小配置

      "maxEntrypointSize": 900000000,

      "maxAssetSize": 90000000,

      "hints": false

    }

}

  config.optimization = {

    runtimeChunk: 'single',

    splitChunks: {

      chunks: 'all',

      maxInitialRequests: Infinity,

      maxSize: 20000,

      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('@', '')}`

          }

}

}

}

  };

},
