核心架构组件

1. 应用入口和路由

Next.js App Router 结构

// app/layout.tsx - 根布局
export default async function RootLayout({
  children,
}: Readonly<{
  children: React.ReactNode;
}>) {
  return (
    <html lang="en" suppressHydrationWarning>
      <head>
        <meta name="viewport" content="width=device-width, initial-scale=1" />
        <link rel="icon" href="/favicon.ico" />
      </head>
      <body className={cn(inter.className, "antialiased")}>
        <Providers
          attribute="class"
          defaultTheme="system"
          enableSystem
          disableTransitionOnChange
        >
          <div className="flex min-h-screen flex-col">
            <Navbar />
            <main className="flex-1">{children}</main>
          </div>
          <Toaster />
        </Providers>
        <Analytics />
      </body>
    </html>
  );
}

提供者组件架构

// app/providers.tsx - 全局提供者
export function Providers({ children, ...props }: ThemeProviderProps) {
  const queryClient = getQueryClient();
  return (
    <QueryClientProvider client={queryClient}>
      <NuqsAdapter>
        <NextThemesProvider {...props}>
          <BackendAPIProvider>
            <CredentialsProvider>
              <LaunchDarklyProvider>
                <OnboardingProvider>
                  <TooltipProvider>{children}</TooltipProvider>
                </OnboardingProvider>
              </LaunchDarklyProvider>
            </CredentialsProvider>
          </BackendAPIProvider>
        </NextThemesProvider>
      </NuqsAdapter>
    </QueryClientProvider>
  );
}

2. 状态管理系统

React Query 配置

// lib/react-query/queryClient.ts
export function getQueryClient() {
  if (typeof window === "undefined") {
    // 服务端：总是创建新的查询客户端
    return makeQueryClient();
  } else {
    // 浏览器端：创建查询客户端（如果不存在）
    if (!browserQueryClient) browserQueryClient = makeQueryClient();
    return browserQueryClient;
  }
}

function makeQueryClient() {
  return new QueryClient({
    defaultOptions: {
      queries: {
        // 使用SSR时，我们通常希望将staleTime设置为0以上
        // 以避免立即在客户端重新获取
        staleTime: 60 * 1000, // 1分钟
        gcTime: 5 * 60 * 1000, // 5分钟
        retry: (failureCount, error) => {
          // 不重试4xx错误
          if (error instanceof Error && error.message.includes('4')) {
            return false;
          }
          return failureCount < 3;
        },
      },
    },
  });
}

后端API上下文

// lib/autogpt-server-api/context.tsx
const BackendAPIProviderContext = createContext<BackendAPI | null>(null);

export function BackendAPIProvider({
  children,
}: {
  children?: React.ReactNode;
}): React.ReactNode {
  const api = useMemo(() => new BackendAPI(), []);

  // 开发环境下暴露API到全局对象用于调试
  if (process.env.NEXT_PUBLIC_BEHAVE_AS == "LOCAL" && !isServerSide()) {
    window.api = api;
  }

  return (
    <BackendAPIProviderContext.Provider value={api}>
      {children}
    </BackendAPIProviderContext.Provider>
  );
}

export function useBackendAPI(): BackendAPI {
  const context = React.useContext(BackendAPIProviderContext);
  if (!context) {
    throw new Error(
      "useBackendAPI must be used within a BackendAPIProviderContext",
    );
  }
  return context;
}

3. 核心自定义Hook

          />
          
          <Control
            onClick={() => runAgent()}
            disabled={isRunning || !savedAgent}
            loading={isRunning}

          />
        </ControlPanel>
      </ReactFlow>
    </div>
  );
};

5. 组件库系统

原子组件示例

// components/atoms/Button/Button.tsx
interface ButtonProps extends React.ButtonHTMLAttributes<HTMLButtonElement> {
  variant?: "default" | "destructive" | "outline" | "secondary" | "ghost" | "link";
  size?: "default" | "sm" | "lg" | "icon";
  loading?: boolean;
}

const Button = React.forwardRef<HTMLButtonElement, ButtonProps>(
  ({ className, variant = "default", size = "default", loading, children, disabled, ...props }, ref) => {
    return (
      <button
        className={cn(buttonVariants({ variant, size, className }))}
        ref={ref}
        disabled={disabled || loading}
        {...props}
      >
        {loading && <Loader2 className="mr-2 h-4 w-4 animate-spin" />}
        {children}
      </button>
    );
  }
);

分子组件示例

// components/molecules/Toast/Toast.tsx
interface ToastProps {
  title?: string;
  description?: string;
  variant?: "default" | "destructive";
  action?: React.ReactNode;
}

export function Toast({ title, description, variant = "default", action }: ToastProps) {
  return (
    <div className={cn(
      "group pointer-events-auto relative flex w-full items-center justify-between space-x-4 overflow-hidden rounded-md border p-6 pr-8 shadow-lg transition-all",
      variant === "destructive" && "destructive border-destructive bg-destructive text-destructive-foreground"
    )}>
      <div className="grid gap-1">
        {title && <div className="text-sm font-semibold">{title}</div>}
        {description && <div className="text-sm opacity-90">{description}</div>}
      </div>
      {action}
    </div>
  );
}

API接口集成

1. 自动生成的API客户端

OpenAPI代码生成

// lib/autogpt-server-api/client.ts - 自动生成的API客户端
export class BackendAPI {
  private baseURL: string;
  private wsClient: WebSocketClient | null = null;

  constructor() {
    this.baseURL = getApiBaseUrl();
  }

  // Graph相关API
  async listGraphs(): Promise<GraphMeta[]> {
    const response = await fetch(`${this.baseURL}/api/v1/graphs`, {
      method: 'GET',
      credentials: 'include',
      headers: {
        'Content-Type': 'application/json',
      },
    });

    if (!response.ok) {
      throw new Error(`Failed to list graphs: ${response.statusText}`);
    }

    return response.json();
  }

  async createGraph(graph: CreateGraphRequest): Promise<Graph> {
    const response = await fetch(`${this.baseURL}/api/v1/graphs`, {
      method: 'POST',
      credentials: 'include',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify(graph),
    });

    if (!response.ok) {
      throw new Error(`Failed to create graph: ${response.statusText}`);
    }

    return response.json();
  }

  async executeGraph(
    graphId: string,
    version: number,
    request: ExecuteGraphRequest
  ): Promise<GraphExecution> {
    const response = await fetch(
      `${this.baseURL}/api/v1/graphs/${graphId}/execute/${version}`,
      {
        method: 'POST',
        credentials: 'include',
        headers: {
          'Content-Type': 'application/json',
        },
        body: JSON.stringify(request),
      }
    );

    if (!response.ok) {
      throw new Error(`Failed to execute graph: ${response.statusText}`);
    }

    return response.json();
  }

  // Block相关API
  async listBlocks(): Promise<Block[]> {
    const response = await fetch(`${this.baseURL}/api/v1/blocks`, {
      method: 'GET',
      credentials: 'include',
      headers: {
        'Content-Type': 'application/json',
      },
    });

    if (!response.ok) {
      throw new Error(`Failed to list blocks: ${response.statusText}`);
    }

    return response.json();
  }

  // WebSocket连接
  connectWebSocket(): void {
    if (this.wsClient) return;

    const wsUrl = this.baseURL.replace(/^http/, 'ws') + '/ws';
    this.wsClient = new WebSocketClient(wsUrl);
    
    this.wsClient.connect();
  }

  disconnectWebSocket(): void {
    if (this.wsClient) {
      this.wsClient.disconnect();
      this.wsClient = null;
    }
  }

  onWebSocketMessage(callback: (message: any) => void): void {
    if (this.wsClient) {
      this.wsClient.onMessage(callback);
    }
  }
}

2. React Query集成

查询Hook生成

// lib/autogpt-server-api/queries.ts - React Query集成
export function useListGraphs() {
  const api = useBackendAPI();
  
  return useQuery({
    queryKey: ['graphs'],
    queryFn: () => api.listGraphs(),
    staleTime: 5 * 60 * 1000, // 5分钟
    gcTime: 10 * 60 * 1000, // 10分钟
  });
}

export function useCreateGraph() {
  const api = useBackendAPI();
  const queryClient = useQueryClient();
  
  return useMutation({
    mutationFn: (graph: CreateGraphRequest) => api.createGraph(graph),
    onSuccess: () => {
      // 创建成功后刷新图列表
      queryClient.invalidateQueries({ queryKey: ['graphs'] });
    },
  });
}

export function useExecuteGraph() {
  const api = useBackendAPI();
  
  return useMutation({
    mutationFn: ({ 
      graphId, 
      version, 
      request 
    }: { 
      graphId: string; 
      version: number; 
      request: ExecuteGraphRequest;
    }) => api.executeGraph(graphId, version, request),
  });
}

export function useListBlocks() {
  const api = useBackendAPI();
  
  return useQuery({
    queryKey: ['blocks'],
    queryFn: () => api.listBlocks(),
    staleTime: 10 * 60 * 1000, // 10分钟，块变化较少
    gcTime: 30 * 60 * 1000, // 30分钟
  });
}

性能优化策略

1. 代码分割和懒加载

// 路由级别的代码分割
const BuildPage = lazy(() => import('@/app/(platform)/build/page'));
const MarketplacePage = lazy(() => import('@/app/(platform)/marketplace/page'));
const LibraryPage = lazy(() => import('@/app/(platform)/library/page'));

// 组件级别的懒加载
const FlowEditor = lazy(() => import('@/components/legacy-builder/Flow/Flow'));
const BlocksPanel = lazy(() => import('@/components/legacy-builder/BlocksPanel'));

// 使用Suspense包装
function App() {
  return (
    <Suspense fallback={<LoadingSpinner />}>
      <Routes>
        <Route path="/build" element={<BuildPage />} />
        <Route path="/marketplace" element={<MarketplacePage />} />
        <Route path="/library" element={<LibraryPage />} />
      </Routes>
    </Suspense>
  );
}

2. 状态优化

// 使用useMemo优化昂贵计算
const availableBlocks = useMemo(() => {
  return allBlocks.filter(
    (block) => !betaBlocks || !betaBlocks.includes(block.id),
  );
}, [allBlocks, betaBlocks]);

// 使用useCallback优化函数引用
const handleNodeChange = useCallback(
  (changes: NodeChange[]) => {
    setXYNodes(nodes => applyNodeChanges(changes, nodes));
  },
  [setXYNodes],
);

// 使用React.memo优化组件渲染
const CustomNode = React.memo(({ data, selected }: NodeProps) => {
  return (
    <div className={cn("custom-node", selected && "selected")}>
      {/* 节点内容 */}
    </div>
  );
});

3. 虚拟化和分页

// 使用react-window进行虚拟化
import { FixedSizeList as List } from 'react-window';

function BlocksList({ blocks }: { blocks: Block[] }) {
  const Row = ({ index, style }: { index: number; style: React.CSSProperties }) => (
    <div style={style}>
      <BlockItem block={blocks[index]} />
    </div>
  );

  return (
    <List
      height={600}
      itemCount={blocks.length}
      itemSize={80}
      width="100%"
    >
      {Row}
    </List>
  );
}

实战经验

1. 状态管理最佳实践

状态分层

服务端状态: 使用React Query管理，自动缓存和同步
客户端状态: 使用useState和useReducer管理本地状态
全局状态: 使用Context API管理跨组件状态
持久化状态: 使用localStorage和sessionStorage

状态更新优化

// 批量状态更新
const updateMultipleStates = useCallback(() => {
  startTransition(() => {
    setNodes(newNodes);
    setEdges(newEdges);
    setSelectedNode(null);
  });
}, []);

// 防抖状态更新
const debouncedSave = useMemo(
  () => debounce((data) => saveToServer(data), 1000),
  []
);

2. 性能监控和优化

性能指标监控

// 使用Performance API监控
function measurePerformance(name: string, fn: () => void) {
  performance.mark(`${name}-start`);
  fn();
  performance.mark(`${name}-end`);
  performance.measure(name, `${name}-start`, `${name}-end`);
  
  const measure = performance.getEntriesByName(name)[0];
  console.log(`${name} took ${measure.duration}ms`);
}

// 组件渲染性能监控
function useRenderCount(componentName: string) {
  const renderCount = useRef(0);
  
  useEffect(() => {
    renderCount.current += 1;
    console.log(`${componentName} rendered ${renderCount.current} times`);
  });
}

内存泄漏预防

// 清理定时器和监听器
useEffect(() => {
  const timer = setInterval(() => {
    // 定时任务
  }, 1000);
  
  const handleResize = () => {
    // 处理窗口大小变化
  };
  
  window.addEventListener('resize', handleResize);
  
  return () => {
    clearInterval(timer);
    window.removeEventListener('resize', handleResize);
  };
}, []);

// 取消未完成的请求
useEffect(() => {
  const abortController = new AbortController();
  
  fetchData({ signal: abortController.signal })
    .then(setData)
    .catch(error => {
      if (error.name !== 'AbortError') {
        console.error('Fetch error:', error);
      }
    });
  
  return () => {
    abortController.abort();
  };
}, []);

3. 用户体验优化

加载状态管理

// 统一的加载状态管理
function useAsyncOperation<T>(
  operation: () => Promise<T>,
  dependencies: any[] = []
) {
  const [data, setData] = useState<T | null>(null);
  const [loading, setLoading] = useState(false);
  const [error, setError] = useState<Error | null>(null);
  
  const execute = useCallback(async () => {
    setLoading(true);
    setError(null);
    
    try {
      const result = await operation();
      setData(result);
      return result;
    } catch (err) {
      setError(err instanceof Error ? err : new Error('Unknown error'));
      throw err;
    } finally {
      setLoading(false);
    }
  }, dependencies);
  
  return { data, loading, error, execute };
}

错误边界和错误处理

// 错误边界组件
class ErrorBoundary extends React.Component<
  { children: React.ReactNode; fallback?: React.ComponentType<{ error: Error }> },
  { hasError: boolean; error: Error | null }
> {
  constructor(props: any) {
    super(props);
    this.state = { hasError: false, error: null };
  }
  
  static getDerivedStateFromError(error: Error) {
    return { hasError: true, error };
  }
  
  componentDidCatch(error: Error, errorInfo: React.ErrorInfo) {
    console.error('Error caught by boundary:', error, errorInfo);
    // 发送错误到监控服务
    Sentry.captureException(error, { extra: errorInfo });
  }
  
  render() {
    if (this.state.hasError) {
      const FallbackComponent = this.props.fallback || DefaultErrorFallback;
      return <FallbackComponent error={this.state.error!} />;
    }
    
    return this.props.children;
  }
}

4. 可访问性和国际化

可访问性支持

// 键盘导航支持
function useKeyboardNavigation(items: any[], onSelect: (item: any) => void) {
  const [selectedIndex, setSelectedIndex] = useState(0);
  
  useEffect(() => {
    const handleKeyDown = (event: KeyboardEvent) => {
      switch (event.key) {
        case 'ArrowUp':
          event.preventDefault();
          setSelectedIndex(prev => Math.max(0, prev - 1));
          break;
        case 'ArrowDown':
          event.preventDefault();
          setSelectedIndex(prev => Math.min(items.length - 1, prev + 1));
          break;
        case 'Enter':
          event.preventDefault();
          onSelect(items[selectedIndex]);
          break;
      }
    };
    
    document.addEventListener('keydown', handleKeyDown);
    return () => document.removeEventListener('keydown', handleKeyDown);
  }, [items, selectedIndex, onSelect]);
  
  return selectedIndex;
}

// ARIA属性支持
function AccessibleButton({ 
  children, 
  onClick, 
  disabled, 
  ariaLabel 
}: {
  children: React.ReactNode;
  onClick: () => void;
  disabled?: boolean;
  ariaLabel?: string;
}) {
  return (
    <button
      onClick={onClick}
      disabled={disabled}
      aria-label={ariaLabel}
      aria-disabled={disabled}
      role="button"
      tabIndex={disabled ? -1 : 0}
    >
      {children}
    </button>
  );
}

5. 测试策略

单元测试

// 组件测试
import { render, screen, fireEvent } from '@testing-library/react';
import { Button } from './Button';

describe('Button', () => {
  it('renders correctly', () => {
    render(<Button>Click me</Button>);
    expect(screen.getByRole('button')).toHaveTextContent('Click me');
  });
  
  it('handles click events', () => {
    const handleClick = jest.fn();
    render(<Button onClick={handleClick}>Click me</Button>);
    
    fireEvent.click(screen.getByRole('button'));
    expect(handleClick).toHaveBeenCalledTimes(1);
  });
  
  it('shows loading state', () => {
    render(<Button loading>Click me</Button>);
    expect(screen.getByRole('button')).toBeDisabled();
    expect(screen.getByTestId('loading-spinner')).toBeInTheDocument();
  });
});

集成测试

// Hook测试
import { renderHook, act } from '@testing-library/react';
import { useAgentGraph } from './useAgentGraph';

describe('useAgentGraph', () => {
  it('saves agent correctly', async () => {
    const { result } = renderHook(() => useAgentGraph());
    
    act(() => {
      result.current.setAgentName('Test Agent');
      result.current.setAgentDescription('Test Description');
    });
    
    await act(async () => {
      await result.current.saveAgent();
    });
    
    expect(result.current.savedAgent).toBeTruthy();
    expect(result.current.savedAgent?.name).toBe('Test Agent');
  });
});
