Vue+ ArcGIS JavaScript APi详解
安迪小宝 人气:17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'
