一、安装nodejs

二、安装electron（主程序）

npm install electron -g

三、安装electron-packager（打包用）

npm install electron-packager -g

四、uniapp的manifest.json修改

五、h5打包

注意：h5打包不需要输入网站域名，直接打包即可

六、h5文件夹下新建package.json和main.js

package.json

{
  "name"    : "app-name",
  "version" : "0.1.0",
  "main"    : "main.js"
}

main.js

const {app, BrowserWindow,ipcMain  } = require('electron')
const fs=require('fs')
const electron = require('electron')
const path = require('path')
const url = require('url')

// ipcMain.on('asynchronous-message', function(event, arg) {
//    // arg是从渲染进程返回来的数据
//   console.log(arg,1);
  
//   // 这里是传给渲染进程的数据C:/Users/Administrator/Desktop/test.txt
//   fs.readFile(path.join(__dirname,"./test.txt"),"utf8",(err,data)=>{
//   	if(err){
// 		event.sender.send('asynchronous-reply', "读取失败");
// 	}else{
// 		event.sender.send('asynchronous-reply', data);
// 	}
    
//   })
// });

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let win
const Menu = electron.Menu
function createWindow () {
  // Create the browser window.
  Menu.setApplicationMenu(null)
  win = new BrowserWindow({
	  fullscreen: true,
	  webPreferences: {
	  nodeIntegration: true, // 使渲染进程拥有node环境
	  
	  }
	  })

  // and load the index.html of the app.
  win.loadURL(url.format({
    pathname: path.join(__dirname, 'index.html'),
    protocol: 'file:',
    slashes: true
  }))
//cpu
	
	
  // Open the DevTools.
win.webContents.openDevTools()
  // Emitted when the window is closed.
  win.on('closed', () => {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    win = null
  })
  
  // ipcMain.on('asynchronous-message', function(event, arg) {
  //    // arg是从渲染进程返回来的数据
  //   console.log(arg,2);
    
  //   // 这里是传给渲染进程的数据C:/Users/Administrator/Desktop/test.txt
  //   fs.readFile(path.join(__dirname,"./test.txt"),"utf8",(err,data)=>{
  //   	if(err){
  // 		event.sender.send('asynchronous-reply', "读取失败");
  // 	}else{
  // 		event.sender.send('asynchronous-reply', data);
  // 	}
      
  //   })
  // });
}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow)

// Quit when all windows are closed.
app.on('window-all-closed', () => {
  // On macOS it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

app.on('activate', () => {
  // On macOS it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (win === null) {
    createWindow()
  }
})

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.

七、electron-packager打包

electron-packager . MyApp --win --out MyApp --arch=x64 --electron-version 12.0.7 --overwrite --ignore=node_modules

八、给软件新增菜单

1. main.js文件加贴入代码

const {
  app,
  BrowserWindow
} = require('electron'); //引入electron
let win;
let windowConfig = {
  width: 800,
  height: 600
}; //窗口配置程序运行窗口的大小
function createWindow() {
  win = new BrowserWindow(windowConfig); //创建一个窗口
  win.loadURL(`file://${__dirname}/index.html`); //在窗口内要展示的内容index.html 就是打包生成的index.html
  win.webContents.openDevTools(); //开启调试工具
  win.on('close', () => {
    //回收BrowserWindow对象
    win = null;
  });
  win.on('resize', () => {
    win.reload();
  })
}
app.on('ready', createWindow);
app.on('window-all-closed', () => {
  app.quit();
});
app.on('activate', () => {
  if (win == null) {
    createWindow();
  }
});

2. package.json文件贴入代码

{
"name": "cang",
"productName": "cang",
"author": "cang",
"version": "1.1.1",
"main": "main.js",
"description": "cang",
"scripts": {
"pack": "electron-builder --dir",
"dist": "electron-builder",
"postinstall": "electron-builder install-app-deps"
},
"build": {
"electronVersion": "1.8.4",
"win": {
"requestedExecutionLevel": "highestAvailable",
"target": [
{
"target": "nsis",
"arch": [
"x64"
]
}
]
},
"appId": "cang",
"artifactName": "cang-version−{arch}.${ext}",
"nsis": {
"artifactName": "cang-version−{arch}.${ext}"
},
"extraResources": [
{
"from": "",
"to": "app-server",
"filter": [
"**/*"
]
}
],
"publish": [
{
"provider": "generic",
"url": "cang"
}
]
},
"dependencies": {
"core-js": "^2.4.1",
"electron-updater": "^4.0.0",
"fs-extra": "^4.0.1",
"install.js": "^1.0.1",
"moment": "^2.18.1",
"moment-es6": "^1.0.0",
"electron-packager": "^12.1.0"
},
"devDependencies": {},
"license": "ISC"
}

这样打包之后就出现头部菜单了
细节补充：

• 在打包命令最后加 --icon=图标名 可以更换.exe图标
• 打包命令MyApp为.exe的名称，可以改为自己的软件名
