第五章工程化与部署

5.1 微前端架构设计

🧩 模块联邦核心

// config/module-federation.config.js
export default {
  name: 'graphicsApp',
  filename: 'remoteEntry.js',
  exposes: {
    './CanvasCore': './src/core/canvas/Engine.ts',
    './StateManager': './src/core/state/Store.ts'
  },
  shared: {
    'react': { singleton: true },
    'three': { eager: true }
  }
};

// 动态加载模块
const RemoteComponent = React.lazy(() =>
  import('designSystem/Button').catch(() => 
    import('./FallbackButton')
  )
);

5.2 WebWorker多线程优化

🚀 渲染任务拆分

// core/threading/RenderScheduler.ts
class RenderScheduler {
  private workerPool: Worker[] = [];
  
  constructor() {
    // 🧵 初始化Worker线程池
    for (let i = 0; i < navigator.hardwareConcurrency; i++) {
      this.workerPool.push(new Worker('./render.worker.ts'));
    }
  }

  async renderFrame(frameData: FrameData) {
    const chunks = this.splitData(frameData);
    const promises = chunks.map((chunk, i) => 
      this.runInWorker(chunk, this.workerPool[i % this.workerPool.length])
    );
    
    return Promise.all(promises);
  }

  private runInWorker(data: any, worker: Worker): Promise<ImageBitmap> {
    return new Promise((resolve) => {
      const channel = new MessageChannel();
      worker.postMessage({ data, port: channel.port2 }, [channel.port2]);
      channel.port1.onmessage = (e) => resolve(e.data);
    });
  }
}

5.3 渲染性能监控体系

📊 实时性能面板

// core/monitoring/PerformanceTracker.ts
class RenderMonitor {
  private stats = new Stats();
  private memoryPanel = new MemoryPanel();
  
  constructor() {
    this.stats.showPanel(0); // 帧率面板
    document.body.appendChild(this.stats.dom);
    
    // 🧠 内存监控
    setInterval(() => {
      this.memoryPanel.update({
        jsHeap: performance.memory.jsHeapSizeLimit,
        usedHeap: performance.memory.usedJSHeapSize
      });
    }, 1000);
  }

  beginFrame() {
    this.stats.begin();
  }

  endFrame() {
    this.stats.end();
  }
}

// WebGL扩展监控
const ext = gl.getExtension('EXT_disjoint_timer_query');
const query = gl.createQuery();
gl.beginQuery(ext.TIME_ELAPSED_EXT, query);

5.4 自动化测试方案

🧪 渲染结果验证

// tests/render.test.ts
describe('Canvas渲染测试', () => {
  let referenceImage: ImageData;
  
  beforeAll(async () => {
    referenceImage = await loadReferenceImage('base-line.png');
  });

  test('图形渲染一致性', async () => {
    const testImage = await generateTestImage();
    const diff = pixelMatch(
      referenceImage.data,
      testImage.data,
      null,
      800, 600,
      { threshold: 0.1 }
    );
    expect(diff).toBeLessThan(100); // 差异像素<100
  });
});

5.5 跨平台打包方案

📦 容器化部署

# Dockerfile
FROM node:18 as build
WORK /app
COPY package*.json ./
RUN npm install --production
COPY . .
RUN npm run build

FROM nginx:alpine
COPY --from=build /app/dist /usr/share/nginx/html
COPY nginx.conf /etc/nginx/conf.d/default.conf
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

5.6 灰度发布策略

🔄 渐进式发布

// server/deploy/CanaryRelease.ts
class CanaryController {
  private readonly CANARY_RATIO = 0.1;
  
  shouldServeCanary(req: Request): boolean {
    const userIdHash = hash(req.ip + req.headers['user-agent']);
    return userIdHash % 100 < this.CANARY_RATIO * 100;
  }

  async rolloutNewVersion() {
    const newVersion = await this.buildNewVersion();
    this.switchTraffic(newVersion, {
      step: 5,  // 每次增加5%流量
      interval: '10m',
      healthCheck: this.checkVersionHealth
    });
  }
}
