vue+arcgis api for javascript初始项目

先安装好node.js,vue环境了,下面开始

1。确定一个项目目录,如e:\aaaa

2、cmd中转到目录,vue create arcgis-test1

就选择第一个 vue cli v4.5.11

vue+arcgis api for javascript初始项目

 3。安装好之后,转到目录e:\aaaa\arcgis-test1

npm install --save esri-loader

4、然后就用vscode 右键打开项目了,开始编码

把components 目录下初始来的helloworld.vue 删除,添加一个map001.vue 

导包
