cesium打包优化

<link href="https://cesium.com/downloads/cesiumjs/releases/1.74/Build/Cesium/Widgets/widgets.css" rel="stylesheet">

  <script src="https://cesium.com/downloads/cesiumjs/releases/1.74/Build/Cesium/Cesium.js"></script>

index.html直接引入依赖 

 

因为生产环境不需要错误提示, 关闭js.map文件

productionSourceMap: false,

代码打包配置

  chainWebpack: (config) => {

    config.resolve.alias

      .set('@$', resolve('src'))

      .set('@api', resolve('src/api'))

      .set('@assets', resolve('src/assets'))

      .set('@comp', resolve('src/components'))

      .set('@views', resolve('src/views'))

    //生产环境，开启js\css压缩

    config.plugin('compressionPlugin').use(new CompressionPlugin({

      test: /\.(js|css|less)$/, // 匹配文件名

      threshold: 10240, // 对超过10k的数据压缩

      deleteOriginalAssets: false // 不删除源文件

    }))

  },
