vue中使用echarts来绘制中国地图,NuxtJS制作疫情地图，内有详细注释，我就懒得解释了，vue cli制作疫情地图 代码略有不同哦~~~

我的代码自我感觉----注释一向十分详细，就不用过多解释都是什么了~~

因为最近疫情期间在家实在是没事干，想找点事，就练手了个小demo

首先上 NuxtJs版本代码，这里面

export default {
  mode: 'universal',
  /*

    title: process.env.npm_package_name || '',

      { hid: 'description', name: 'description', content: process.env.npm_package_description || '' }
    ],
    link: [
      { rel: 'icon', type: 'image/x-icon', href: '/favicon.ico' }
    ]
  },

  axios: {

  build: {

    extend (config, ctx) {
      config.module.rules.push({
        enforce: 'pre',
        test: /\.(js|vue)$/,
        loader: 'eslint-loader',

        options: {

        }
      })
    }
  }
}
