electron与cesium组件入门应用功能

运行应用效果图：
在这里插入图片描述

electron应用目录，需要包括三个文件:
index.html
main.js
package.json

(一)、创建一个新项目
目录名称：project_helloWolrd

(二)、生成package.json文件

npm init --yes

(三）、运行该项目方法一
在终端cmd输入如下命令：

electron .

(四)、运行该项目方法二
#==========================================
#start cli cammand
全局安装

cnpm install -g electron @electron-forge/cli

#build cli electron-builder
打exe安装包我们使用electron-builder工具包，安装命令如下。
全局安装

cnpm install -g electron-builder

开始/打包生成exe文件

npm run start
npm run build

#==========================================
注意，json文件不能带注释，复制上面的文本后记得注释去掉。
修改package.json，添加一条scripts命令和build配置。

 "scripts": {"start": "electron-forge start","build": "electron-builder --win" // 打包命令},"devDependencies": {"@electron-forge/cli": "^6.2.1","electron": "^25.4.0","electron-builder": "^24.6.3"},"dependencies": {"cesium": "^1.112.0","@electron-forge/cli": "^6.2.1"},// `electron-builder`配置"build": {"productName": "我的应用", // 安装应用后桌面名称"directories": {"output": "out" // 输出的文件目录},"win": {"icon": "./ico/logo.ico", // 安装的图标"target": [{"target": "nsis","arch": ["x64","ia32"]}]},"nsis": {"oneClick": false,"allowElevation": true,"allowToChangeInstallationDirectory": true,"installerIcon": "./ico/logo.ico","uninstallerIcon": "./ico/logo.ico","installerHeaderIcon": "./ico/logo.ico","createDesktopShortcut": true,"createStartMenuShortcut": true,"shortcutName": "我的应用"}}

#==========================================
#如果报错，可以采用node_modules目录删除，重新下载依赖包

cnpm install

#cesium安装cmd命令： //OK

cnpm install cesium --save

（五)、源代码
main.js主程序文件内容：

const { app,BrowserWindow}=require("electron");
const path=require("path");const createWindow=()=>{const mainWindow=new BrowserWindow({width:600,height:400,});mainWindow.loadFile(path.join(__dirname,'indexCesium.html'));    //index.html  indexCesium.html////mainWindow.loadURL("https://gitee.com");//mainWindow.loadURL("https://blog.csdn.net/hsg77");
}//监听应用启动事件
app.on("ready",createWindow);
