React懒加载组件失败了怎么办？如何优雅地处理React.lazy加载失败及优化策略？

const ModuleA = React.lazy(() => {
    return new Promise((resolve, reject) => {
        import('moduleWrap')
            .then(module => resolve(module))
            .catch(err => { /* 处理错误 */ });
    });
});

import React, { Component, lazy, Suspense } from 'react';

// 错误边界
class ErrorBoundary extends Component {
  state = { hasError: false };

  static getDerivedStateFromError(error) {
    return { hasError: true };
  }

  componentDidCatch(error, info) {
    // 记录错误到错误报告服务
  }

  render() {
    if (this.state.hasError) {
      return <h1>加载失败</h1>;
    }
    return this.props.children;
  }
}

// 重试逻辑
function withRetry(importPromise, maxRetries = 3) {
  let retryCount = 0;
  function tryImport() {
    return importPromise().catch(error => {
      if (retryCount < maxRetries) {
        retryCount++;
        console.log(`重试加载组件，第 ${retryCount} 次尝试...`);
        return new Promise(resolve => setTimeout(resolve, 1000)).then(tryImport);
      }
      throw error; // 抛出错误给 ErrorBoundary 处理
    });
  }
  return tryImport;
}

const LazyComponent = lazy(withRetry(() => import('./LazyComponent')));

// 使用懒加载组件
function MyComponent() {
  return (
    <ErrorBoundary>
      <Suspense fallback={<div>加载中...</div>}>
        <LazyComponent />
      </Suspense>
    </ErrorBoundary>
  );
}
