new AppWindow()

3.4 预加载脚本配置

// electron/preload.js
import { contextBridge, ipcRenderer } from 'electron'

// 暴露安全的API给渲染进程
contextBridge.exposeInMainWorld('electronAPI', {
  // 窗口控制
  minimizeWindow: () => ipcRenderer.invoke('window-minimize'),
  maximizeWindow: () => ipcRenderer.invoke('window-maximize'),
  closeWindow: () => ipcRenderer.invoke('window-close'),

  // 文件操作
  showSaveDialog: (options) => ipcRenderer.invoke('show-save-dialog', options),
  showOpenDialog: (options) => ipcRenderer.invoke('show-open-dialog', options),

  // 系统操作
  openExternal: (url) => ipcRenderer.invoke('open-external', url),

  // 应用事件
  onNewFile: (callback) => ipcRenderer.on('new-file-created', callback),

  // 移除监听器
  removeAllListeners: (channel) => ipcRenderer.removeAllListeners(channel)
})

// 类型定义
contextBridge.exposeInMainWorld('env', {
  platform: process.platform,
  version: process.versions.electron
})

五、实际应用场景

5.1 现代化代码编辑器

// src/utils/fileOperations.ts
import { dialog } from 'electron'

export class FileOperations {
  static async openFile(): Promise<{ path: string; content: string } | null> {
    try {
      const result = await dialog.showOpenDialog({
        filters: [
          { name: 'All Files', extensions: ['*'] },
          { name: 'Text Files', extensions: ['txt', 'md'] },
          { name: 'Code Files', extensions: ['js', 'ts', 'vue', 'html', 'css'] }
        ],
        properties: ['openFile']
      })
      
      if (!result.canceled && result.filePaths.length > 0) {
        const path = result.filePaths[0]
        const content = await this.readFileContent(path)
        return { path, content }
      }
      return null
    } catch (error) {
      console.error('Open file error:', error)
      throw error
    }
  }
  
  static async saveFile(content: string, defaultPath?: string): Promise<string | null> {
    try {
      const result = await dialog.showSaveDialog({
        defaultPath,
        filters: [
          { name: 'All Files', extensions: ['*'] },
          { name: 'Text Files', extensions: ['txt'] },
          { name: 'Markdown', extensions: ['md'] },
          { name: 'JavaScript', extensions: ['js'] },
          { name: 'TypeScript', extensions: ['ts'] }
        ]
      })
      
      if (!result.canceled && result.filePath) {
        await this.writeFileContent(result.filePath, content)
        return result.filePath
      }
      return null
    } catch (error) {
      console.error('Save file error:', error)
      throw error
    }
  }
  
  private static async readFileContent(path: string): Promise<string> {
    // 在实际应用中,这里会调用Electron的fs模块
    // 这里使用模拟实现
    return new Promise((resolve) => {
      setTimeout(() => {
        resolve(`// Content of ${path}\nconsole.log('Hello World');`)
      }, 100)
    })
  }
  
  private static async writeFileContent(path: string, content: string): Promise<void> {
    // 在实际应用中,这里会调用Electron的fs模块
    console.log(`Writing content to ${path}`)
  }
}

5.2 系统托盘应用

// electron/trayManager.ts
import { app, Tray, Menu, nativeImage } from 'electron'
import { join } from 'path'

export class TrayManager {
  private tray: Tray | null = null
  
  constructor(private mainWindow: Electron.BrowserWindow) {}
  
  createTray() {
    // 创建托盘图标
    const iconPath = join(__dirname, '../assets/tray-icon.png')
    const trayIcon = nativeImage.createFromPath(iconPath)
    
    this.tray = new Tray(trayIcon.resize({ width: 16, height: 16 }))
    
    // 托盘菜单
    const contextMenu = Menu.buildFromTemplate([
      {
        label: '显示窗口',
        click: () => {
          this.mainWindow.show()
          this.mainWindow.focus()
        }
      },
      {
        label: '新建文件',
        click: () => {
          this.mainWindow.webContents.send('tray-new-file')
        }
      },
      { type: 'separator' },
      {
        label: '退出',
        click: () => {
          app.quit()
        }
      }
    ])
    
    this.tray.setContextMenu(contextMenu)
    this.tray.setToolTip('My Electron App')
    
    // 托盘图标点击事件
    this.tray.on('click', () => {
      this.toggleWindow()
    })
    
    // 双击事件
    this.tray.on('double-click', () => {
      this.mainWindow.show()
      this.mainWindow.focus()
    })
  }
  
  private toggleWindow() {
    if (this.mainWindow.isVisible()) {
      this.mainWindow.hide()
    } else {
      this.mainWindow.show()
      this.mainWindow.focus()
    }
  }
  
  destroy() {
    if (this.tray) {
      this.tray.destroy()
      this.tray = null
    }
  }
}

六、测试与质量保证

6.1 单元测试配置

// vitest.config.js
import { defineConfig } from 'vitest/config'
import vue from '@vitejs/plugin-vue'

export default defineConfig({
  plugins: [vue()],
  test: {
    environment: 'happy-dom',
    globals: true,
    setupFiles: ['./tests/setup.js'],
    coverage: {
      reporter: ['text', 'html', 'lcov'],
      exclude: [
        '**/node_modules/**',
        '**/dist/**',
        '**/electron/**',
        '**/*.config.js'
      ]
    }
  }
})

6.2 组件测试示例

// tests/components/FileEditor.spec.ts
import { describe, it, expect, vi } from 'vitest'
import { mount } from '@vue/test-utils'
import FileEditor from '@/components/FileEditor.vue'
import { useAppStore } from '@/stores/appStore'

// 模拟Electron API
vi.stubGlobal('electronAPI', {
  readFile: vi.fn(),
  writeFile: vi.fn()
})

// 模拟Pinia store
vi.mock('@/stores/appStore', () => ({
  useAppStore: vi.fn()
}))

describe('FileEditor', () => {
  const mockAppStore = {
    currentFile: {
      id: '1',
      name: 'test.js',
      path: '/path/to/test.js',
      content: 'console.log("hello")',
      modified: new Date(),
      isDirty: false
    },
    displayName: 'test.js',
    hasUnsavedChanges: false,
    saveFile: vi.fn(),
    settings: {
      fontSize: 14
    }
  }
  
  beforeEach(() => {
    vi.mocked(useAppStore).mockReturnValue(mockAppStore)
  })
  
  it('renders file content correctly', () => {
    const wrapper = mount(FileEditor, {
      props: {
        content: 'console.log("test")'
      }
    })
    
    expect(wrapper.find('textarea').element.value).toBe('console.log("test")')
  })
  
  it('emits update event when content changes', async () => {
    const wrapper = mount(FileEditor, {
      props: {
        content: 'initial'
      }
    })
    
    const textarea = wrapper.find('textarea')
    await textarea.setValue('updated content')
    
    expect(wrapper.emitted('update:content')).toBeTruthy()
    expect(wrapper.emitted('update:content')![0]).toEqual(['updated content'])
  })
  
  it('handles save shortcut', async () => {
    const wrapper = mount(FileEditor, {
      props: {
        content: 'content to save'
      }
    })
    
    // 模拟Ctrl+S快捷键
    const event = new KeyboardEvent('keydown', {
      ctrlKey: true,
      key: 's'
    })
    
    await wrapper.find('textarea').element.dispatchEvent(event)
    
    expect(mockAppStore.saveFile).toHaveBeenCalledWith('content to save')
  })
})

6.3 E2E 测试配置

// tests/e2e/example.spec.js
import { test, expect } from '@playwright/test'

test('basic app functionality', async ({ page }) => {
  // 启动应用(需要先启动开发服务器)
  await page.goto('http://localhost:5173')
  
  // 检查应用标题
  await expect(page.locator('h1')).toContainText('My Electron App')
  
  // 测试文件操作
  await page.click('button:has-text("New File")')
  await expect(page.locator('.file-name')).toContainText('Untitled')
  
  // 测试编辑功能
  const editor = page.locator('textarea')
  await editor.fill('console.log("Hello World")')
  await expect(editor).toHaveValue('console.log("Hello World")')
})

七、打包与部署

7.1 生产环境构建配置

// electron-builder.config.js
module.exports = {
  appId: 'com.yourcompany.yourapp',
  productName: 'Your App',

    'electron/**/*',
    'node_modules/**/*',
    'package.json'
  ],
  extraMetadata: {
    main: 'electron/main.js'
  },
  mac: {
    category: 'public.app-category.developer-tools',
    icon: 'build/icon.icns',
    target: [
      {
        target: 'dmg',

        message: `A new version ${info.version} is available. Do you want to download it now?`,
        buttons: ['Download', 'Later']
      }).then((result) => {
        if (result.response === 0) {
          autoUpdater.downloadUpdate()
        }
      })
    })
    
    autoUpdater.on('update-not-available', (info) => {
      this.mainWindow.webContents.send('update-status', 'up-to-date')
    })
    
    autoUpdater.on('download-progress', (progress) => {
      this.mainWindow.webContents.send('download-progress', progress)

    autoUpdater.on('update-downloaded', (info) => {
      this.mainWindow.webContents.send('update-downloaded', info)
      
      dialog.showMessageBox(this.mainWindow, {
        type: 'info',
        title: 'Update Ready',
        message: 'The update has been downloaded. Restart the application to apply the update?',
        buttons: ['Restart', 'Later']
      }).then((result) => {
        if (result.response === 0) {
          autoUpdater.quitAndInstall()
        }
      })
    })
    
    autoUpdater.on('error', (error) => {
      this.mainWindow.webContents.send('update-error', error)
      console.error('Update error:', error)
    })
