vue3+vite项目引入electron运行为桌面项目

一、安装electron

javascript 复制代码

npm install --save-dev electron

二、项目根目录添加electron文件

在此文件夹中添加两个js文件：main.js、preload.js

main.js:

javascript 复制代码

// 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: 800,
    height: 600,
    webPreferences: {
      preload: path.join(__dirname, 'preload.js')
    }
  })

  // and load the index.html of the app.
  mainWindow.loadFile('index.html')

  // Open the DevTools.
  // mainWindow.webContents.openDevTools()
}

// 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.

preload.js:

javascript 复制代码

/**
 * The preload script runs before `index.html` is loaded
 * in the renderer. It has access to web APIs as well as
 * Electron's renderer process modules and some polyfilled
 * Node.js functions.
 *
 * https://www.electronjs.org/docs/latest/tutorial/sandbox
 */
window.addEventListener('DOMContentLoaded', () => {
  const replaceText = (selector, text) => {
    const element = document.getElementById(selector)
    if (element) element.innerText = text
  }

  for (const type of ['chrome', 'node', 'electron']) {
    replaceText(`${type}-version`, process.versions[type])
  }
})

三、配置package.json文件

删除："type": "module"

添加："main": "electron/main.js",

添加："start": "electron ."

示例：

javascript 复制代码

{
  "name": "electron_vue3",
  "private": true,
  "version": "0.0.0",
  "main": "electron/main.js",
  "scripts": {
    "dev": "vite",
    "build": "vue-tsc -b && vite build",
    "preview": "vite preview",
    "start": "electron ."
  },
  "dependencies": {
    "vue": "^3.5.13"
  },
  "devDependencies": {
    "@types/node": "^22.10.10",
    "@vitejs/plugin-vue": "^5.2.1",
    "@vue/tsconfig": "^0.7.0",
    "electron": "^34.0.1",
    "typescript": "~5.6.2",
    "vite": "^6.0.5",
    "vue-tsc": "^2.2.0"
  }
}

四、运行

javascript 复制代码

// 运行为桌面项目
npm run start

// 运行为网页
npm run dev
