Vue+ ArcGIS JavaScript APi详解
版本Vue 2
ArcGIS JavaScript 4.22
注意 ArcGIS JavaScript3.x 和ArcGIS JavaScript 4.x框架差异较大
环境搭建
新建vue
可以使用vue ui创建项目
增加ArcGIS JavaScript 包引用
package.json
"dependencies": {
"core-js": "^3.8.3",
"vue": "^2.6.14",
"@arcgis/core":"4.22.2",
"ncp":"^2.0.0"
},
"devDependencies": {
"@babel/core": "^7.12.16",
"@babel/eslint-parser": "^7.12.16",
"@vue/cli-plugin-babel": "~5.0.0",
"@vue/cli-plugin-eslint": "~5.0.0",
"@vue/cli-service": "~5.0.0",
"eslint": "^6.8.0",
"eslint-plugin-vue": "^5.2.3",
"vue-template-compiler": "^2.6.14"
},ncp: 主要用于拷贝资源信息
@arcgis/core 是arcgis_js仓库
拷贝资源信息
package.json中配置copy命令
"scripts": {
"serve": "vue-cli-service serve",
"build": "vue-cli-service build",
"lint": "vue-cli-service lint",
"copy": "ncp ./node_modules/@arcgis/core/assets ./public/assets"
},安装完依赖后运行 copy命令
yarn
yarn copy
yarn serve
-------------------
npm i
npm run copy
npm run serve运行完copy命令后,会将arcgis相关资源拷贝到public/assets目录下
全局引入
main.js
import '@arcgis/core/assets/esri/themes/light/main.css'
import esriConfig from '@arcgis/core/config.js'
esriConfig.assetsPath = './assets'
