electron与cesium组件入门应用功能
运行应用效果图:
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);
