说明: vue2项目,使用的vue-element-admin框架,用electron打包成.exe文件。

1、新建一个文件夹,然后右键打开终端或者cd到这个目录。执行下面的命令(最好确认一下github网站是否登陆了)。

1
2
//将electron官网中的quick-start拉取到本地
git clone https://github.com/electron/electron-quick-start


安装成功的文件如下显示:

2.安装好后,用vscode(其他类似工具)打开,新建终端,前后输入下面的命令。

//下载项目需要的依赖
npm install

//安装打包.exe所需要的依赖electron-packager、electron
npm i electron-packager --save-dev
npm i electron --save-dev

//运行看看是否可以成功
npm run start

如果运行成功,会弹出一个页面,如下图:


3、删除electron-quick-start文件中的index.html,把自己的项目dist文件放进去。

4、打开electron-quick-start文件里的main.js文件,下面是mian.js完整代码。
重点是: mainWindow.loadFile(“./dist/index.html”) 的修改

// Modules to control application life and create native browser window
const { app, BrowserWindow } = require("electron");
const path = require("node:path");

function createWindow() {
// Create the browser window.
const mainWindow = new BrowserWindow({
width: 1024, //自己需要的宽高
height: 960,
webPreferences: {
preload: path.join(__dirname, "preload.js"),
},
});

// and load the index.html of the app.
mainWindow.loadFile("./dist/index.html");
// Open the DevTools.
mainWindow.webContents.openDevTools(); // 打开调试工具
}

// 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.whenReady().then(() => {
createWindow();

app.on("activate", function () {
// 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 (BrowserWindow.getAllWindows().length === 0) createWindow();
});
});

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

// 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.

5、打开 package.json文件,添加上有关packager的代码。
(PS: 如果不需要自动匹配dist文件夹下的应用图标使用该内容
“electron-packager ./ Vite App --platform=win32 --arch=x64 --overwrite”)

"scripts": {
"start": "electron .",
"packager": "electron-packager ./ 你想用的exe名字 --platform=win32 --arch=x64 --icon=./dist/favicon.ico --overwrite"
},

6、终于到了最后一步:npm run packager进行打包!打包成功后如下图

1
npm run packager

7、其它

如果想electron打包后自带服务,将electron-quick-start文件里的main.js文件修改如下:

const { app, BrowserWindow } = require("electron");
const express = require("express");
const expressApp = express();

expressApp.get("/", (req, res) => {
res.send("Hello World!");
});

const server = expressApp.listen(3000, () => {
console.log("Server is running on http://localhost:3000");
});

app.on("ready", () => {
const mainWindow = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
nodeIntegration: true,
contextIsolation: false // 如果你使用的是Electron 12及以上版本,推荐启用contextIsolation并使用preload脚本
}
});
mainWindow.loadURL("http://localhost:3000");

mainWindow.on("closed", () => {
server.close();
});

});

// 处理应用退出逻辑
app.on("window-all-closed", () => {
// 在macOS上,应用通常在用户明确退出前保持活动状态
if (process.platform !== "darwin") {
app.quit();
}
});
