🪟 智能窗口管理系统

核心组件架构
// WindowManager 采用组合模式,将职责委托给专门的管理器
class WindowManager {
  private windowStore: WindowStore;        // 核心门面
  private pluginExecutor: PluginExecutor;  // 插件系统
  private lifecycle: WindowLifecycle;      // 生命周期管理
  private metricsManager: MetricsManager;  // 性能监控
}

// WindowStore 协调四大核心模块
class WindowStore {
  private registry: WindowRegistry;        // 窗口注册表
  private operator: WindowOperator;        // 窗口操作器
  private stateManager: WindowStateManager; // 状态持久化
  private contextManager: WindowContextManager; // 上下文管理
}
1. WindowRegistry - 窗口注册表

职责:管理窗口存储映射和分组关系

class WindowRegistry {
  // 核心映射关系
  private windows: Map<string, BrowserWindow>;           // ID -> 窗口实例
  private windowNames: Map<string, string>;              // 名称 -> ID
  private windowIds: Map<string, string>;                // ID -> 名称
  private windowInstanceIds: Map<BrowserWindow, string>; // 实例 -> ID
  
  // 分组管理
  private groups: Map<string, Set<string>>;              // 组名 -> 窗口ID集合
  private windowGroups: Map<string, Set<string>>;        // 窗口ID -> 组名集合
  
  // 智能清理机制
  startCleanupProtection(intervalMs: number): void {
    // 定期清理已销毁的窗口,防止内存泄漏
    this.cleanupTimer = setInterval(() => {
      this.cleanupDestroyedWindows();
    }, intervalMs);
  }
}

特性

  • 双向索引 - 支持通过 ID、名称、实例快速查找
  • 分组管理 - 支持窗口分组,批量操作
  • 内存保护 - 自动清理已销毁窗口,防止内存泄漏
  • 分块处理 - 大量窗口时分块处理,避免阻塞主线程
2. WindowOperator - 窗口操作器

职责:封装所有窗口操作,提供安全检查

class WindowOperator {
  // 安全检查
  isSafe(window?: BrowserWindow | null): window is BrowserWindow {
    return !!window && !window.isDestroyed();
  }
  
  // 统一的窗口操作
  show(window: BrowserWindow): void {
    if (!this.isSafe(window)) return;
    window.show();
    window.setSkipTaskbar(false);
  }
  
  // 开发者工具管理
  openDevTools(window: BrowserWindow): void;
  closeDevTools(window: BrowserWindow): void;
  isDevToolsOpened(window: BrowserWindow): boolean;
}

特性

  • 安全第一 - 所有操作前都进行安全检查
  • 操作统一 - 统一的窗口操作接口
  • 开发支持 - 内置开发者工具管理
3. WindowStateManager - 状态持久化管理器

职责:管理窗口状态的持久化和恢复

class WindowStateManager {
  private stateKeeper: StateKeeper;
  
  manage(name: string, window: BrowserWindow, getGroups?: () => string[]): void {
    const saveState = () => {
      const bounds = window.getBounds();
      const isMaximized = window.isMaximized();
      const display = screen.getDisplayMatching(bounds);
      
      this.stateKeeper.saveState(name, {
        x: bounds.x, y: bounds.y,
        width: bounds.width, height: bounds.height,
        isMaximized, isFullScreen: window.isFullScreen(),
        displayBounds: display.bounds,
        groups: getGroups ? getGroups() : undefined,
      });
    };
    
    // 监听所有状态变化事件
    window.on('resize', saveState);
    window.on('move', saveState);
    window.on('maximize', saveState);
    // ... 更多事件
  }
}

StateKeeper 高级特性

class StateKeeper {
  // 智能保存策略
  private saveStrategy: 'debounce' | 'throttle';
  
  // 原子写入保护
  private async performSave(): Promise<void> {
    const tempFile = `${this.stateFile}.tmp`;
    
    // 1. 写入临时文件
    await fs.promises.writeFile(tempFile, data);
    // 2. 原子重命名(大多数文件系统上是原子操作)
    await fs.promises.rename(tempFile, this.stateFile);
  }
  
  // 状态验证
  private isValidState(state: WindowState): boolean {
    const displays = screen.getAllDisplays();
    // 检查窗口是否在可用显示器范围内
    return displays.some(display => /* 相交检查 */);
  }
}

特性

  • 防抖/节流 - 可配置的保存策略,避免频繁 IO
  • 原子写入 - 使用临时文件确保数据完整性
  • 状态验证 - 确保恢复的窗口在可用显示器范围内
  • 多实例保护 - 防止多个实例同时写入同一文件
  • MD5 优化 - 只在数据真正变化时才写入磁盘
4. 焦点历史管理
class WindowStore {
  private focusHistory: string[] = [];
  
  pushFocus(windowId: string): void {
    // 移除已存在的(移动到顶部)
    this.focusHistory = this.focusHistory.filter(id => id !== windowId);
    this.focusHistory.push(windowId);
  }
  
  getPreviousFocusedWindow(): string | undefined {
    // 返回上一个聚焦的窗口
    return this.focusHistory[this.focusHistory.length - 2];
  }
}
5. 窗口分组系统
// 创建窗口并加入组
const editorWindow = await windowManager.create({
  name: 'editor-main',
  title: '主编辑器',
  groups: ['editor-group', 'main-windows']
});

// 批量操作组内窗口
await windowManager.closeGroup('editor-group');
windowManager.hideGroup('tool-windows');
windowManager.focusGroup('main-windows');

🔌 类型安全的 IPC 路由系统

核心架构
class IpcRouter<Api, Schema> {
  private dispatcher: MessageDispatcher<Api>;  // 消息分发器
  private rateLimiter: RateLimiter;           // 限流器
  
  // 添加处理器
  addHandler<K extends keyof Schema>(
    handler: IpcHandler<Api, Schema[K]['payload'], Schema[K]['response']>
  ): void {
    this.dispatcher.register(handler.name, handler.callback, handler.schema);
  }
}
1. IpcHandler - 处理器定义
class IpcHandler<Context, T, R> {
  constructor(
    private name: string,
    private event: string,
    private callback: IpcHandlerCallback<Context, T, R>,
    private schema?: ZodType<T>  // Zod 验证 schema
  ) {}
}

// 使用示例
const getUserHandler = new IpcHandler(
  'getUser',
  'user',
  async (context, payload: { id: string }) => {
    // 可以访问注入的 API
    const db = context.api.database;
    const user = await db.users.findById(payload.id);
    return { success: true, data: user };
  },
  z.object({ id: z.string().min(1) })  // 运行时验证
);
2. MessageDispatcher - 消息分发器
class MessageDispatcher<Context> {
  private handlers = new Map<string, {
    callback: HandlerCallback<Context, any, any>;
    metadata?: any;  // 存储 Zod schema 等元数据
  }>();
  
  dispatch<T, R>(name: string, context: Context, data: T): R | undefined {
    const entry = this.handlers.get(name);
    if (!entry) return undefined;
    
    try {
      // 执行处理器
      return entry.callback(context, data);
    } catch (error) {
      this.logger.error(`Error in handler "${name}": ${error}`);
      if (this.errorHandler) {
        return this.errorHandler(error, name);
      }
      throw error;
    }
  }
}
3. RateLimiter - 智能限流器
class RateLimiter {
  private limits = new Map<string, RateLimitConfig>();
  private state = new Map<string, RateLimitState>();
  
  check(key: string, ruleKey: string): boolean {
    const config = this.limits.get(ruleKey) || this.defaultLimit;
    if (!config) return true;
    
    const now = Date.now();
    let record = this.state.get(key);
    
    if (!record || now > record.resetTime) {
      record = {
        count: 0,
        resetTime: now + config.interval,
      };
      this.state.set(key, record);
    }
    
    if (record.count >= config.limit) {
      this.logger.warn(`Rate limit exceeded for ${key}`);
      return false;
    }
    
    record.count++;
    return true;
  }
}

// 使用示例
ipcRouter.setRateLimit('expensiveOperation', {
  limit: 10,      // 10次调用
  interval: 60000 // 每分钟
});
4. 依赖注入系统
// 主进程中注册服务
const context = {
  api: {
    database: new DatabaseService(),
    fileSystem: new FileSystemService(),
    notification: new NotificationService(),
  },
  window: {
    getWinId: () => getCurrentWindowId(),
    minimize: (id) => windowManager.minimize(id),
    // ... 更多窗口操作
  }
};

// 处理器中使用注入的服务
const saveFileHandler = new IpcHandler(
  'saveFile',
  'file',
  async (context, payload: { path: string, content: string }) => {
    // 使用注入的文件系统服务
    await context.api.fileSystem.writeFile(payload.path, payload.content);
    
    // 使用注入的通知服务
    context.api.notification.show('文件保存成功');
    
    return { success: true };
  },
  z.object({
    path: z.string().min(1),
    content: z.string()
  })
);

🌉 高性能消息总线系统

核心架构
class MessageBus extends EventEmitter {
  // 核心管理器
  private subscriptionManager: SubscriptionManager;  // 订阅管理
  private transactionManager: TransactionManager;    // 事务管理
  private dataStoreManager: DataStoreManager;        // 数据存储管理
  
  // 传输层
  private transport: ITransport;  // MessagePort 或 IPC 传输
  private windows: Map<string, BrowserWindow>;
}
1. DataStoreManager - 数据存储管理器
class DataStoreManager {
  private dataStore: Map<string, DataStoreItem> = new Map();
  
  // 权限检查
  checkPermission(
    key: string, 
    windowId: string | undefined, 
    operation: 'modify' | 'delete'
  ): { success: boolean; error?: string } {
    const item = this.dataStore.get(key);
    
    if (item?.permission) {
      if (item.permission.readonly) {
        return { success: false, error: `Field "${key}" is readonly` };
      }
      
      if (item.permission.allowedWindows && windowId) {
        if (!item.permission.allowedWindows.includes(windowId)) {
          return {
            success: false,
            error: `Window "${windowId}" is not allowed to ${operation} "${key}"`
          };
        }
      }
    }
    
    return { success: true };
  }
}
2. SubscriptionManager - 订阅管理器
class SubscriptionManager {
  private subscriptions: Map<string, Set<string>> = new Map(); // key -> windowIds
  private readonly MAX_SUBSCRIPTIONS_PER_KEY = 100;
  
  subscribe(windowId: string, keys: string[]): void {
    keys.forEach(key => {
      if (!this.subscriptions.has(key)) {
        this.subscriptions.set(key, new Set());
      }
      const subscribers = this.subscriptions.get(key)!;
      subscribers.add(windowId);
      
      // 内存泄漏检测
      if (subscribers.size > this.MAX_SUBSCRIPTIONS_PER_KEY) {
        this.logger.warn(
          `High number of subscriptions (${subscribers.size}) for key: "${key}"`
        );
      }
    });
  }
}
3. TransactionManager - 事务管理器
class TransactionManager {
  private buffers: Map<string, Map<string, TransactionOperation>> = new Map();
  
  // 开启事务
  start(windowId: string): void {
    this.buffers.set(windowId, new Map());
  }
  
  // 提交事务
  commit(windowId: string): Map<string, TransactionOperation> | undefined {
    const buffer = this.buffers.get(windowId);
    if (buffer) {
      this.buffers.delete(windowId);
      return buffer;
    }
    return undefined;
  }
  
  // 添加操作到事务缓冲区
  add(windowId: string, key: string, op: TransactionOperation): boolean {
    if (this.buffers.has(windowId)) {
      this.buffers.get(windowId)!.set(key, op);
      return true;
    }
    return false;
  }
}

// 使用示例
messageBus.startTransaction('window-1');
messageBus.setData('user.name', 'Alice');
messageBus.setData('user.age', 25);
messageBus.setData('user.email', 'alice@example.com');
messageBus.commitTransaction('window-1'); // 批量提交
4. MessagePortTransport - 高性能传输层
class MessagePortTransport implements ITransport {
  private portManager: PortManager;
  
  registerWindow(windowId: string, window: BrowserWindow): void {
    this.portManager.register(windowId, window, (msg, _port) => {
      if (this.onMessage) {
        this.onMessage(msg, windowId);
      }
    });
  }
  
  broadcast(message: any, windowIds?: string[]): number {
    const serialized = typeof message === 'string' ? message : JSON.stringify(message);
    return this.portManager.broadcast(serialized, windowIds);
  }
}

MessagePort vs IPC 性能对比

⚙️ 配置管理系统

class ConfigManager extends TypedEmitter<ConfigManagerEvents> {
  private config: Record<string, any> = {};
  private schema?: z.ZodType<any>;
  
  // 支持点符号访问
  get<T>(key: string, defaultValue?: T): T {
    return this.getDeep(this.config, key) ?? defaultValue;
  }
  
  set(key: string, value: any): void {
    // Zod 验证
    if (this.schema) {
      const tempConfig = JSON.parse(JSON.stringify(this.config));
      this.setDeep(tempConfig, key, value);
      const result = this.schema.safeParse(tempConfig);
      if (!result.success) {
        throw new Error(`Configuration validation failed: ${result.error.message}`);
      }
    }
    
    const oldValue = this.get(key);
    this.setDeep(this.config, key, value);
    this.emit('change', key, value, oldValue);
    
    if (this.autoSave) {
      this.triggerSave();
    }
  }
}

// 使用示例
const configManager = new ConfigManager({
  schema: z.object({
    ui: z.object({
      theme: z.enum(['light', 'dark']),
      language: z.string(),
    }),
    window: z.object({
      width: z.number().min(400),
      height: z.number().min(300),
    })
  })
});

configManager.set('ui.theme', 'dark');
configManager.set('window.width', 1200);

🐛 调试与性能监控系统

PerformanceMonitor - 性能监控器
class PerformanceMonitor {
  private static instance: PerformanceMonitor;
  private metrics: Map<string, PerformanceMetric> = new Map();
  
  startMeasure(id: string, name: string, metadata?: any): void {
    this.metrics.set(id, {
      name,
      startTime: performance.now(),
      metadata,
    });
  }
  
  endMeasure(id: string, additionalMetadata?: any): number | undefined {
    const metric = this.metrics.get(id);
    if (!metric) return undefined;
    
    const duration = performance.now() - metric.startTime;
    this.logger.info(`[Performance] ${metric.name}: ${duration.toFixed(2)}ms`);
    
    this.metrics.delete(id);
    return duration;
  }
}

// 使用示例
const monitor = PerformanceMonitor.getInstance();
monitor.startMeasure('window-creation', 'Create Main Window');
await windowManager.create({ name: 'main' });
monitor.endMeasure('window-creation'); // 输出: [Performance] Create Main Window: 45.23ms

🔄 生命周期管理器

class LifecycleManager {
  async startup(): Promise<void> {
    this.logger.info('Starting up Electron Toolkit services...');
    
    // 1. 初始化 IpcRouter (通信基础)
    this.ipcRouter = new IpcRouter({ logger: this.logger });
    
    // 2. 初始化 MessageBus (跨窗口通信)
    this.messageBus = new MessageBus({ logger: this.logger });
    
    // 3. 初始化 WindowManager (核心窗口管理)
    this.windowManager = new WindowManager({
      ...this.config,
      ipcRouter: this.ipcRouter,
      messageBus: this.messageBus,
    });
    await this.windowManager.ready();
    
    // 4. 连接 MessageBus 到 WindowManager
    this.messageBus.autoRegisterWindows(this.windowManager);
    
    // 5. 启用调试模式
    if (this.config.isDevelopment) {
      DebugHelper.enableDebugMode();
      DebugHelper.register('windowManager', this.windowManager);
      DebugHelper.register('ipcRouter', this.ipcRouter);
      DebugHelper.register('messageBus', this.messageBus);
    }
    
    this.isStarted = true;
  }
  
  async shutdown(): Promise<void> {
    // 按初始化的逆序关闭
    if (this.messageBus) this.messageBus.dispose();

🏗️ 架构设计亮点

分层架构设计

应用层 (开发者代码)
    ↓
核心层 (WindowManager, IpcRouter, MessageBus)
    ↓
支撑层 (WindowStore, PluginExecutor, DI Container)
    ↓
基础设施层 (ConfigManager, Logger, DebugHelper)
    ↓
Electron 运行时

设计模式应用

  • 组合模式 - WindowStore 作为核心门面,职责清晰
  • 插件系统 - 标准化的扩展机制,支持自定义功能
  • 依赖注入 - IPC 处理器中的 DI 容器,解耦业务逻辑
  • 事件驱动 - 完整的生命周期钩子,支持自定义扩展
  • 消息代理 - MessageBus 的统一通信接口

    // 注册编辑器特定的 IPC 处理器
    ipcRouter.addHandler(new IpcHandler(
      'openFile',
      'editor',
      async (context, { filePath }) => {
        const content = await fs.readFile(filePath, 'utf-8');

    const cached = this.cache.get(key);
    if (cached && Date.now() - cached.timestamp < this.CACHE_TTL) {
      return cached.value; // 缓存命中,无需 IPC 调用
    }
    return undefined;
  }
  
  set(key: string, value: any): void {
    this.cache.set(key, { value, timestamp: Date.now() });
  }
  
  // 智能预取
  prefetch(keys: string[]): void {

      if (!this.cache.has(key)) {
        // 异步预取数据
        this.fetchData(key).then(value => this.set(key, value));
      }
    });
  }
}

// 使用示例
const cacheManager = new LocalCacheManager();

// 读取数据时优先使用缓存
const getData = async (key: string) => {
  let value = cacheManager.get(key);
  if (value === undefined) {
    value = await window.api.invoke('getData', { key });
    cacheManager.set(key, value);
  }
  return value;
};
2. 事件节流和防抖
class PerformanceOptimizer {
  private throttleTimers = new Map<string, number>();
  private debounceTimers = new Map<string, NodeJS.Timeout>();
  
  // 节流:限制执行频率
  throttle<T extends (...args: any[]) => any>(
    key: string,
    fn: T,
    interval: number = 16 // 60fps
  ): T {
    return ((...args: any[]) => {
      const now = Date.now();
      const lastTime = this.throttleTimers.get(key) || 0;
      
      if (now - lastTime >= interval) {
        this.throttleTimers.set(key, now);
        return fn(...args);
      }
    }) as T;
  }
  
  // 防抖:延迟执行
  debounce<T extends (...args: any[]) => any>(
    key: string,
    fn: T,
    delay: number = 300
  ): T {
    return ((...args: any[]) => {
      const existingTimer = this.debounceTimers.get(key);
      if (existingTimer) {
        clearTimeout(existingTimer);
      }
      
      const timer = setTimeout(() => {
        this.debounceTimers.delete(key);
        fn(...args);
      }, delay);
      
      this.debounceTimers.set(key, timer);
    }) as T;
  }
}

// 使用示例
const optimizer = new PerformanceOptimizer();

// 高频鼠标移动事件节流
const handleMouseMove = optimizer.throttle('mouse-move', (event) => {
  messageBus.setData('cursor.position', { x: event.clientX, y: event.clientY });
}, 16);

// 搜索输入防抖
const handleSearch = optimizer.debounce('search', (query) => {
  messageBus.setData('search.query', query);
}, 300);
3. 内存管理和清理
class MemoryManager {
  private subscriptions = new Set<() => void>();
  private intervals = new Set<NodeJS.Timeout>();
  private observers = new Set<MutationObserver>();
  
  // 统一的订阅管理
  addSubscription(unsubscribe: () => void): void {
    this.subscriptions.add(unsubscribe);
  }
  
  // 定时器管理
  setInterval(callback: () => void, ms: number): NodeJS.Timeout {
    const timer = setInterval(callback, ms);
    this.intervals.add(timer);
    return timer;
  }
  
  // 观察者管理
  observe(target: Node, options: MutationObserverInit, callback: MutationCallback): MutationObserver {
    const observer = new MutationObserver(callback);
    observer.observe(target, options);
    this.observers.add(observer);
    return observer;
  }
  
  // 统一清理
  cleanup(): void {
    // 清理订阅
    this.subscriptions.forEach(unsubscribe => {
      try {
        unsubscribe();
      } catch (error) {
        console.warn('Cleanup subscription error:', error);
      }
    });
    this.subscriptions.clear();
    
    // 清理定时器
    this.intervals.forEach(timer => clearInterval(timer));
    this.intervals.clear();
    
    // 清理观察者
    this.observers.forEach(observer => observer.disconnect());
    this.observers.clear();
  }
  
  // 内存使用监控
  monitorMemoryUsage(): void {
    if ('memory' in performance) {
      const memory = (performance as any).memory;
      console.log('Memory Usage:', {
        used: Math.round(memory.usedJSHeapSize / 1024 / 1024) + ' MB',
        total: Math.round(memory.totalJSHeapSize / 1024 / 1024) + ' MB',
        limit: Math.round(memory.jsHeapSizeLimit / 1024 / 1024) + ' MB'
      });
    }
  }
}

// Vue 组件中使用
export default {
  setup() {
    const memoryManager = new MemoryManager();
    
    // 添加订阅
    const unsubscribe = messageBus.watch('data', callback);
    memoryManager.addSubscription(unsubscribe);
    
    // 组件卸载时清理
    onUnmounted(() => {
      memoryManager.cleanup();
    });
    
    return { /* ... */ };
  }
};
4. 批量操作优化
class BatchProcessor {
  private batches = new Map<string, {
    operations: Array<{ key: string; value: any; type: 'set' | 'delete' }>;
    timer: NodeJS.Timeout;
  }>();
  
  private readonly BATCH_SIZE = 50;
  private readonly BATCH_DELAY = 100; // 100ms
  
  // 批量设置数据
  batchSet(batchId: string, key: string, value: any): void {
    this.addToBatch(batchId, { key, value, type: 'set' });
  }
  
  // 批量删除数据
  batchDelete(batchId: string, key: string): void {
    this.addToBatch(batchId, { key, value: undefined, type: 'delete' });
  }
  
  private addToBatch(batchId: string, operation: any): void {
    let batch = this.batches.get(batchId);
    
    if (!batch) {
      batch = {
        operations: [],
        timer: setTimeout(() => this.processBatch(batchId), this.BATCH_DELAY)
      };
      this.batches.set(batchId, batch);
    }
    
    batch.operations.push(operation);
    
    // 达到批量大小限制时立即处理
    if (batch.operations.length >= this.BATCH_SIZE) {
      clearTimeout(batch.timer);
      this.processBatch(batchId);
    }
  }
  
  private async processBatch(batchId: string): Promise<void> {
    const batch = this.batches.get(batchId);
    if (!batch) return;
    
    this.batches.delete(batchId);
    
    try {
      // 批量发送到主进程
      await window.api.invoke('batch-operations', {
        operations: batch.operations
      });
      
      console.log(`Processed batch ${batchId} with ${batch.operations.length} operations`);
    } catch (error) {
      console.error('Batch processing failed:', error);
    }
  }
  
  // 强制处理所有待处理批次
  async flush(): Promise<void> {
    const promises = Array.from(this.batches.keys()).map(batchId => {
      const batch = this.batches.get(batchId);
      if (batch) {
        clearTimeout(batch.timer);
        return this.processBatch(batchId);
      }
    });
    
    await Promise.all(promises);
  }
}

// 使用示例
const batchProcessor = new BatchProcessor();

// 批量更新用户界面状态
const updateUIState = (updates: Record<string, any>) => {
  Object.entries(updates).forEach(([key, value]) => {
    batchProcessor.batchSet('ui-updates', key, value);
  });
};

// 页面卸载时确保所有批次都被处理
window.addEventListener('beforeunload', () => {
  batchProcessor.flush();
});

🔧 调试和监控工具

1. 性能监控面板
class PerformanceMonitorPanel {
  private metrics = {
    ipcCalls: 0,
    messagesSent: 0,
    messagesReceived: 0,
    cacheHits: 0,
    cacheMisses: 0,

    renderTime: 0,
  };
  
  private startTime = performance.now();
  
  // 记录 IPC 调用
  recordIpcCall(method: string, duration: number): void {
    this.metrics.ipcCalls++;
    console.log(`IPC Call: ${method} took ${duration.toFixed(2)}ms`);
  }
  
  // 记录消息传递
  recordMessage(type: 'sent' | 'received', size: number): void {
    if (type === 'sent') {
      this.metrics.messagesSent++;
    } else {
      this.metrics.messagesReceived++;
    }
  }
  
  // 记录缓存命中
  recordCacheHit(hit: boolean): void {
    if (hit) {
      this.metrics.cacheHits++;
    } else {

  }
  
  // 获取性能报告
  getPerformanceReport(): any {

    return {
      uptime: Math.round(uptime),
      metrics: this.metrics,
      cacheHitRate: Math.round(cacheHitRate),
      averageIpcTime: this.metrics.ipcCalls > 0 ? uptime / this.metrics.ipcCalls : 0,

  }
  
  // 实时监控
  startRealTimeMonitoring(): void {
    setInterval(() => {
      const report = this.getPerformanceReport();
      console.table(report);
      
      // 发送到主进程进行记录
      window.api.invoke('performance-report', report);

  }
}

// 全局性能监控实例
const performanceMonitor = new PerformanceMonitorPanel();

// 在开发模式下启用
if (process.env.NODE_ENV === 'development') {
  performanceMonitor.startRealTimeMonitoring();
}
2. 内存泄漏检测
class MemoryLeakDetector {
  private snapshots: Array<{ timestamp: number; heapUsed: number }> = [];
  private readonly MAX_SNAPSHOTS = 100;
  private readonly LEAK_THRESHOLD = 10 * 1024 * 1024; // 10MB

    if ('memory' in performance) {
      const memory = (performance as any).memory;
      const snapshot = {
        timestamp: Date.now(),
        heapUsed: memory.usedJSHeapSize
      };
      
      this.snapshots.push(snapshot);
      
      // 保持快照数量限制
      if (this.snapshots.length > this.MAX_SNAPSHOTS) {
        this.snapshots.shift();
      }
      
      this.analyzeMemoryTrend();
    }
  }
  
  private analyzeMemoryTrend(): void {
    if (this.snapshots.length < 10) return;
    
    const recent = this.snapshots.slice(-10);
    const oldest = recent[0];
    const newest = recent[recent.length - 1];
    
    const memoryIncrease = newest.heapUsed - oldest.heapUsed;
    const timeSpan = newest.timestamp - oldest.timestamp;
    
    if (memoryIncrease > this.LEAK_THRESHOLD) {
      console.warn('Potential memory leak detected:', {
        increase: Math.round(memoryIncrease / 1024 / 1024) + ' MB',
        timeSpan: Math.round(timeSpan / 1000) + ' seconds',
        rate: Math.round(memoryIncrease / timeSpan * 1000) + ' bytes/second'
      });
      
      // 触发垃圾回收(如果可用)
      if ('gc' in window) {
        (window as any).gc();
      }
    }
  }
  
  startMonitoring(interval: number = 30000): void {
    setInterval(() => {
      this.takeSnapshot();
    }, interval);
  }
}

// 启用内存泄漏检测
const memoryLeakDetector = new MemoryLeakDetector();

🛠️ 项目初始化

1. 主进程设置
// src/main/index.ts
import { app } from 'electron';
import { createElectronToolkit } from 'electron-infra-kit';
import path from 'path';

app.whenReady().then(async () => {
  // 初始化 Electron Infra Kit
  const { windowManager, ipcRouter, messageBus } = createElectronToolkit({
    // 开发模式配置
    isDevelopment: process.env.NODE_ENV === 'development',
    
    // 默认窗口配置
    defaultConfig: {
      webPreferences: {
        preload: path.join(__dirname, '../preload/index.js'),
        contextIsolation: true,
        nodeIntegration: false,
        webSecurity: true,
      },
    },
    
    // 启用功能
    enablePersistence: true,        // 窗口状态持久化
    performanceMonitoring: true,    // 性能监控
    
    // IPC 配置
    ipc: {
      autoInit: true,               // 自动初始化
      enableRateLimit: true,        // 启用限流
    },
    
    // 日志配置
    loggerOptions: {
      level: 'info',
      appName: 'MyApp',
    },
  });

  // 等待初始化完成
  await windowManager.ready();

  // 注册 IPC 处理器
  const getUserHandler = new IpcHandler(
    'getUser',
    'user',
    async (context, payload: { id: string }) => {
      // 业务逻辑
      const user = await userService.findById(payload.id);
      return { success: true, data: user };
    },
    z.object({ id: z.string().uuid() }) // Zod 验证
  );
  
  ipcRouter.addHandler(getUserHandler);

  // 创建主窗口
  const mainWindowId = await windowManager.create({
    name: 'main',
    title: '我的应用',
    width: 1200,
    height: 800,
    
    // 窗口分组
    groups: ['main-windows'],
    
    // 生命周期钩子

      // 注册窗口到消息总线
      messageBus.registerWindow(windowId, window);
    },

      ? 'http://localhost:5173' 
      : `file://${path.join(__dirname, '../renderer/index.html')}`,
  });

  console.log('应用启动完成,主窗口ID:', mainWindowId);
});

// 应用退出处理
app.on('before-quit', async () => {
  // 优雅关闭
  await windowManager.dispose();
});
2. 预加载脚本设置
// src/preload/index.ts
import { contextBridge, ipcRenderer } from 'electron';
import { ipcRendererBridge, setupMessageBus } from 'electron-infra-kit/preload';

// 配置 IPC 桥接器
ipcRendererBridge.configure({
  apiKey: 'api',

  validatePayload: (channel: string, payload: any) => {
    // 自定义验证逻辑
    if (typeof payload === 'object' && payload !== null) {
      const size = JSON.stringify(payload).length;
      if (size > 1024 * 1024) { // 1MB 限制
        throw new Error('Payload too large');
      }
    }
    return true;
  },
});

// 暴露安全的 API
const bindings = ipcRendererBridge.getBindings();
contextBridge.exposeInMainWorld('api', {
  ...bindings,
  
  // 扩展方法
  invoke: (channel: string, data?: any) => bindings.invoke(channel, data),
  
  // 事件监听
  on: (channel: string, listener: Function) => {
    const subscription = (event: any, ...args: any[]) => listener(event, ...args);
    ipcRenderer.on(channel, subscription);
    return () => ipcRenderer.removeListener(channel, subscription);
  },
  
  // 移除所有监听器
  removeAllListeners: (channel: string) => {
    ipcRenderer.removeAllListeners(channel);
  },
});

// 设置消息总线
setupMessageBus({
  // 消息总线配置
  autoConnect: true,
  reconnectInterval: 5000,
  
  // 错误处理
  onError: (error: Error) => {
    console.error('MessageBus error:', error);
  },
  
  // 连接状态回调
  onConnected: () => {
    console.log('MessageBus connected');
  },
  
  onDisconnected: () => {
    console.log('MessageBus disconnected');
  },
});
