+
+## Development Guidelines
+
+### Component Development Standards
+
+1. **Function Components First**: Use function components and Hooks
+2. **TypeScript Types**: Define interfaces for all props
+3. **Component Naming**: Use PascalCase, file name matches component name
+4. **Single Responsibility**: Each component handles only one functionality
+
+```tsx
+// Example: Button Component
+interface ButtonProps {
+  variant: 'primary' | 'secondary' | 'danger';
+  size?: 'small' | 'medium' | 'large';
+  disabled?: boolean;
+  onClick?: () => void;
+  children: React.ReactNode;
+}
+
+export const Button: React.FC<ButtonProps> = ({
+  variant,
+  size = 'medium',
+  disabled = false,
+  onClick,
+  children
+}) => {
+  return (
+    <button
+      className={`btn btn-${variant} btn-${size}`}
+      disabled={disabled}
+      onClick={onClick}
+    >
+      {children}
+    </button>
+  );
+};
+```
+
+### State Management Standards
+
+Using Zustand for state management:
+
+```tsx
+// store/userStore.ts
+import { create } from 'zustand';
+
+interface User {
+  id: string;
+  name: string;
+  email: string;
+}
+
+interface UserState {
+  user: User | null;
+  isLoading: boolean;
+  setUser: (user: User) => void;
+  clearUser: () => void;
+  setLoading: (loading: boolean) => void;
+}
+
+export const useUserStore = create<UserState>((set) => ({
+  user: null,
+  isLoading: false,
+  setUser: (user) => set({ user }),
+  clearUser: () => set({ user: null }),
+  setLoading: (isLoading) => set({ isLoading }),
+}));
+```
+
+### API Service Standards
+
+```tsx
+// services/api.ts
+import axios from 'axios';
+
+const api = axios.create({
+  baseURL: import.meta.env.VITE_API_URL,
+  timeout: 10000,
+});
+
+// Request interceptor
+api.interceptors.request.use((config) => {
+  const token = localStorage.getItem('token');
+  if (token) {
+    config.headers.Authorization = `Bearer ${token}`;
+  }
+  return config;
+});
+
+// Response interceptor
+api.interceptors.response.use(
+  (response) => response.data,
+  (error) => {
+    console.error('API Error:', error);
+    return Promise.reject(error);
+  }
+);
+
+export default api;
+```
+
+## Environment Setup
+
+### Development Requirements
+- Node.js >= 18.0.0
+- npm >= 8.0.0 or yarn >= 1.22.0
+
+### Installation Steps
+```bash
+# 1. Create project
+npm create vite@latest my-react-app -- --template react-ts
+
+# 2. Navigate to project directory
+cd my-react-app
+
+# 3. Install dependencies
+npm install
+
+# 4. Install additional dependencies
+npm install zustand react-router-dom axios
+npm install -D @types/node
+
+# 5. Start development server
+npm run dev
+```
+
+### Environment Variables Configuration
+```env
+# .env.local
+VITE_API_URL=http://localhost:3001/api
+VITE_APP_TITLE=My React App
+VITE_ENABLE_MOCK=false
+```
+
+## Routing Configuration
+
+```tsx
+// App.tsx
+import { BrowserRouter, Routes, Route } from 'react-router-dom';
+import { HomePage } from './pages/HomePage';
+import { AboutPage } from './pages/AboutPage';
+import { NotFoundPage } from './pages/NotFoundPage';
+
+function App() {
+  return (
+    <BrowserRouter>
+      <Routes>
+        <Route path="/" element={<HomePage />} />
+        <Route path="/about" element={<AboutPage />} />
+        <Route path="*" element={<NotFoundPage />} />
+      </Routes>
+    </BrowserRouter>
+  );
+}
+
+export default App;
+```
+
+## Testing Strategy
+
+### Unit Testing Example
+```tsx
+// tests/components/Button.test.tsx
+import { render, screen, fireEvent } from '@testing-library/react';
+import { Button } from '../src/components/Button';
+
+describe('Button Component', () => {
+  test('renders button with text', () => {
+    render(<Button variant="primary">Click me</Button>);
+    expect(screen.getByText('Click me')).toBeInTheDocument();
+  });
+
+  test('calls onClick when clicked', () => {
+    const handleClick = vi.fn();
+    render(
+      <Button variant="primary" onClick={handleClick}>
+        Click me
+      </Button>
+    );
+    
+    fireEvent.click(screen.getByText('Click me'));
+    expect(handleClick).toHaveBeenCalledTimes(1);
+  });
+});
+```
+
+## Performance Optimization
+
+### Code Splitting
+```tsx
+import { lazy, Suspense } from 'react';
+
+const LazyComponent = lazy(() => import('./LazyComponent'));
+
+function App() {
+  return (
+    <Suspense fallback={<div>Loading...</div>}>
+      <LazyComponent />
+    </Suspense>
+  );
+}
+```
+
+### Memory Optimization
+```tsx
+import { memo, useMemo, useCallback } from 'react';
+
+const ExpensiveComponent = memo(({ data, onUpdate }) => {
+  const processedData = useMemo(() => {
+    return data.map(item => ({ ...item, processed: true }));
+  }, [data]);
+
+  const handleUpdate = useCallback((id) => {
+    onUpdate(id);
+  }, [onUpdate]);
+
+  return (
+    <div>
+      {processedData.map(item => (
+        <div key={item.id} onClick={() => handleUpdate(item.id)}>
+          {item.name}
+        </div>
+      ))}
+    </div>
+  );
+});
+```
+
+## Deployment Configuration
+
+### Build Production Version
+```bash
+npm run build
+```
+
+### Vite Configuration Optimization
+```ts
+// vite.config.ts
+import { defineConfig } from 'vite';
+import react from '@vitejs/plugin-react';
+
+export default defineConfig({
+  plugins: [react()],
+  build: {
+    rollupOptions: {
+      output: {
+        manualChunks: {
+          vendor: ['react', 'react-dom'],
+          router: ['react-router-dom'],
+        },
+      },
+    },
+  },
+  server: {
+    port: 3000,
+    open: true,
+  },
+});
+```
+
+## Common Issues
+
+### Issue 1: Vite Development Server Slow Startup
+**Solution**:
+- Check dependency pre-build cache
+- Use `npm run dev -- --force` to force rebuild
+- Optimize optimizeDeps configuration in vite.config.ts
+
+### Issue 2: TypeScript Type Errors
+**Solution**:
+- Ensure correct type definition packages are installed
+- Check tsconfig.json configuration
+- Use `npm run type-check` for type checking
