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);
