1.开启gzip
2.webpack配置externals三方库（vue、vuex、axios、moment等）
3.移除prefetch
4.修改router.js(相同路由地址报错)
5.cdn/oss静态(图片等)资源

 configureWebpack: {
    plugins: [
      new CompressionPlugin({ // 开启gzip压缩
        test: /\.js$|\.html$|.\css/, //匹配文件名
        threshold: 10240,//对超过10k的数据压缩
        deleteOriginalAssets: false //不删除源文件
      }),
    ],
  },

  # 开启gzip
	gzip on;
	# 匹配压缩类型 js/css
	gzip_types text/plain application/javascript application/x-javascript text/css application/xml text/javascript;

  configureWebpack: {
    // 引用外部库
    externals: {
      'vue': 'Vue',
      'vue-router': 'VueRouter',
      'vuex': 'Vuex',
      'axios': 'axios',
      'moment': 'moment',
      'v-viewer': 'VueViewer',
    },
  },

    <script src="https://cdn/lib/v-viewer/viewer.min.js"></script>
    <script src="https://cdn/lib/v-viewer/v-viewer.min.js"></script>

  chainWebpack: config => {
    // 移除 prefetch 插件
    config.plugins.delete('prefetch')
  },

// 解决两次访问相同路由地址报错
const originalPush = Router.prototype.push;
Router.prototype.push = function push(location) {
  return originalPush.call(this, location);
}
