## Project Structure Guidelines
|
||||
|
||||
### File Organization
|
||||
```
|
||||
src/
|
||||
├── components/ # Reusable UI components
|
||||
├── pages/ # Page components or routes
|
||||
├── hooks/ # Custom React hooks
|
||||
├── utils/ # Utility functions
|
||||
├── services/ # API calls and external services
|
||||
├── types/ # TypeScript type definitions
|
||||
├── constants/ # Application constants
|
||||
├── styles/ # Global styles and themes
|
||||
└── tests/ # Test files
|
||||
```
|
||||
|
||||
### Naming Conventions
|
||||
- **Files**: Use kebab-case for file names (`user-profile.component.ts`)
|
||||
- **Components**: Use PascalCase for component names (`UserProfile`)
|
||||
- **Functions**: Use camelCase for function names (`getUserData`)
|
||||
- **Constants**: Use UPPER_SNAKE_CASE for constants (`API_BASE_URL`)
|
||||
- **Types/Interfaces**: Use PascalCase with descriptive names (`UserData`, `ApiResponse`)
|
||||
|
||||
## TypeScript Guidelines
|
||||
|
||||
### Type Safety
|
||||
- Enable strict mode in `tsconfig.json`
|
||||
- Use explicit types for function parameters and return values
|
||||
- Prefer interfaces over types for object shapes
|
||||
- Use union types for multiple possible values
|
||||
- Avoid `any` type - use `unknown` when type is truly unknown
|
||||
|
||||
### Best Practices
|
||||
- Use type guards for runtime type checking
|
||||
- Leverage utility types (`Partial`, `Pick`, `Omit`, etc.)
|
||||
- Create custom types for domain-specific data
|
||||
- Use enums for finite sets of values
|
||||
- Document complex types with JSDoc comments
|
||||
|
||||
## Code Quality Standards
|
||||
|
||||
### ESLint Configuration
|
||||
- Use recommended ESLint rules for JavaScript/TypeScript
|
||||
- Enable React-specific rules if using React
|
||||
- Configure import/export rules for consistent module usage
|
||||
- Set up accessibility rules for inclusive development
|
||||
|
||||
### Prettier Configuration
|
||||
- Use consistent indentation (2 spaces recommended)
|
||||
- Set maximum line length (80-100 characters)
|
||||
- Use single quotes for strings
|
||||
- Add trailing commas for better git diffs
|
||||
|
||||
### Testing Standards
|
||||
- Aim for 80%+ test coverage
|
||||
- Write unit tests for utilities and business logic
|
||||
- Use integration tests for component interactions
|
||||
- Implement e2e tests for critical user flows
|
||||
- Follow AAA pattern (Arrange, Act, Assert)
|
||||
|
||||
## Performance Optimization
|
||||
|
||||
### Bundle Optimization
|
||||
- Use code splitting for large applications
|
||||
- Implement lazy loading for routes and components
|
||||
- Optimize images and assets
|
||||
- Use tree shaking to eliminate dead code
|
||||
- Analyze bundle size regularly
|
||||
|
||||
### Runtime Performance
|
||||
- Implement proper memoization (React.memo, useMemo, useCallback)
|
||||
- Use virtualization for large lists
|
||||
- Optimize re-renders in React applications
|
||||
- Implement proper error boundaries
|
||||
- Use web workers for heavy computations
|
||||
|
||||
## Security Guidelines
|
||||
|
||||
### Dependencies
|
||||
- Regularly audit dependencies with `npm audit`
|
||||
- Keep dependencies updated
|
||||
- Use lock files (`package-lock.json`, `yarn.lock`)
|
||||
- Avoid dependencies with known vulnerabilities
|
||||
|
||||
### Code Security
|
||||
- Sanitize user inputs
|
||||
- Use HTTPS for API calls
|
||||
- Implement proper authentication and authorization
|
||||
- Store sensitive data securely (environment variables)
|
||||
- Use Content Security Policy (CSP) headers
|
||||
|
||||
## Development Workflow
|
||||
|
||||
### Before Starting
|
||||
1. Check Node.js version compatibility
|
||||
2. Install dependencies with `npm install`
|
||||
3. Copy environment variables from `.env.example`
|
||||
4. Run type checking with `npm run typecheck`
|
||||
|
||||
### During Development
|
||||
1. Use TypeScript for type safety
|
||||
2. Run linter frequently to catch issues early
|
||||
3. Write tests for new features
|
||||
4. Use meaningful commit messages
|
||||
5. Review code changes before committing
|
||||
|
||||
### Before Committing
|
||||
1. Run full test suite: `npm test`
|
||||
2. Check linting: `npm run lint`
|
||||
3. Verify formatting: `npm run format:check`
|
||||
4. Run type checking: `npm run typecheck`
|
||||

2. **Identify hook type**: Determine if creating new custom hook, optimizing existing hook, or implementing specific hook pattern
|
||||
3. **Check TypeScript usage**: Verify if project uses TypeScript and follow typing conventions
|
||||
4. **Implement hook**: Create hook with proper:
|
||||
- Naming convention (use prefix)
|
||||
- TypeScript types and interfaces
|
||||
- Proper dependency arrays
|
||||
- Error handling
|
||||
- Performance optimizations
|
||||
5. **Add tests**: Create comprehensive unit tests using project's testing framework
|
||||
6. **Add documentation**: Include JSDoc comments and usage examples
|
||||
|
||||
## Common Hook Patterns
|
||||
|
||||
When creating hooks, consider these patterns based on the request:
|
||||
- **Data fetching**: API calls, loading states, error handling
|
||||
- **State management**: Local state, derived state, state persistence
|
||||
- **Side effects**: Event listeners, timers, subscriptions
|
||||
- **Context consumption**: Theme, auth, app state
|
||||
- **Form handling**: Input management, validation, submission
|
||||
- **Performance**: Memoization, debouncing, throttling
|
||||
|
||||
## Requirements
|
||||
|
||||
- Follow existing project hook conventions
|
||||
- Use TypeScript if project uses it
|
||||
- Include proper cleanup in useEffect
|
||||
- Add error boundaries where appropriate
|
||||
- Write tests that cover all hook functionality
|
||||
- IMPORTANT: Always check existing hooks first to understand project patterns
|
||||
|
||||
## Notes
|
||||
|
||||
- Ask for clarification if the hook requirements are ambiguous
|
||||
- Suggest optimizations for existing hooks if relevant
|
||||
- Consider accessibility implications for UI-related hooks

# React State Management
|
||||
|
||||
Implement state management solution for $ARGUMENTS following project conventions.
|
||||
|
||||
## Task
|
||||
|
||||
Set up or optimize state management based on the requirements:
|
||||
|
||||
1. **Analyze current setup**: Check existing state management approach and project structure
|
||||
2. **Determine solution**: Based on requirements, choose appropriate state management:
|
||||
- Context API for simple, localized state
|
||||
- Redux Toolkit for complex, global state
|
||||
- Zustand for lightweight global state
|
||||
- Custom hooks for component-level state
|
||||
3. **Examine dependencies**: Check package.json for existing state management libraries
|
||||
4. **Implement solution**: Create store, providers, and hooks with proper TypeScript types
|
||||
5. **Set up middleware**: Add devtools, persistence, or other middleware as needed
|
||||
6. **Create typed hooks**: Generate properly typed selectors and dispatch hooks
|
||||
7. **Add tests**: Write unit tests for state logic and reducers
|
||||
8. **Update providers**: Integrate with app's provider hierarchy
|
||||
|
||||
## Implementation Requirements
|
||||
|
||||
- Follow project's TypeScript conventions
|
||||
- Use existing state management patterns if present
|
||||
- Create proper type definitions for state shape
|
||||
- Include error handling and loading states
|
||||
- Add proper debugging setup (devtools)
|
||||
- Consider performance optimizations (selectors, memoization)
|
||||
|
||||
## State Management Selection Guide
|
||||
|
||||
Choose based on complexity:
|
||||
- **Simple state**: React hooks + Context API
|
||||
- **Medium complexity**: Zustand or custom hooks
|
||||
- **Complex state**: Redux Toolkit with RTK Query
|
||||
- **Form state**: React Hook Form or Formik
|
||||
|
||||
## Important Notes
|
||||
|
||||
- ALWAYS check existing state management first
|
||||
- Don't install new dependencies without asking
|
||||
- Follow project's folder structure for state files
|
||||
- Consider server state vs client state separation
|
||||
- Add proper TypeScript types for all state interfaces

## When to Use This Agent
|
||||
|
||||
Use this agent for:
|
||||
- Slow loading React applications
|
||||
- Janky or unresponsive user interactions
|
||||
- Large bundle sizes affecting load times
|
||||
- Memory leaks or excessive memory usage
|
||||
- Poor Core Web Vitals scores
|
||||
- Performance regression analysis
|
||||
|
||||
## Performance Audit Framework
|
||||
|
||||
### 1. Initial Performance Assessment
|
||||
```javascript
|
||||
// Performance measurement setup
|
||||
const measurePerformance = (name, fn) => {
|
||||
const start = performance.now();
|
||||
const result = fn();
|
||||
const end = performance.now();
|
||||
console.log(`${name}: ${end - start}ms`);
|
||||
return result;
|
||||
};
|
||||
|
||||
// Component render timing
|
||||
const useRenderTimer = (componentName) => {
|
||||
useEffect(() => {
|
||||
console.log(`${componentName} rendered at ${performance.now()}`);
|
||||
});
|
||||
};
|
||||
```
|
||||
|
||||
### 2. Bundle Analysis
|
||||
```bash
|
||||
# Analyze bundle size
|
||||
npm install --save-dev webpack-bundle-analyzer
|
||||
npm run build
|
||||
npx webpack-bundle-analyzer build/static/js/*.js
|
||||
|
||||
# Bundle size budget in package.json
|
||||
{
|
||||
"bundlesize": [
|
||||
{
|
||||
"path": "./build/static/js/*.js",
|
||||
"maxSize": "300kb"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
## Rendering Optimization Strategies
|
||||
|
||||
### React.memo for Component Memoization
|
||||
```javascript
|
||||
// Expensive component that should only re-render when props change
|
||||
const ExpensiveComponent = React.memo(({ data, onUpdate }) => {
|
||||
const processedData = useMemo(() => {
|
||||
return data.map(item => ({
|
||||
...item,
|
||||
computed: heavyComputation(item)
|
||||
}));
|
||||
}, [data]);
|
||||
|
||||
return (
|
||||
<div>
|
||||
{processedData.map(item => (
|
||||
<Item key={item.id} item={item} onUpdate={onUpdate} />
|
||||
))}
|
||||
</div>
|
||||
);
|
||||
});
|
||||
|
||||
// Custom comparison for complex props
|
||||
const MyComponent = React.memo(({ user, settings }) => {
|
||||
return <div>{user.name}</div>;
|
||||
}, (prevProps, nextProps) => {
|
||||
return prevProps.user.id === nextProps.user.id &&
|
||||
prevProps.settings.theme === nextProps.settings.theme;
|
||||
});
|
||||
```
|
||||
|
||||
### useCallback and useMemo Optimization
|
||||
```javascript
|
||||
const OptimizedParent = ({ items, filter }) => {
|
||||
// Memoize expensive calculations
|
||||
const filteredItems = useMemo(() => {
|
||||
return items.filter(item =>
|
||||
item.name.toLowerCase().includes(filter.toLowerCase())
|
||||
);
|
||||
}, [items, filter]);
|
||||
|
||||
// Memoize event handlers to prevent child re-renders
|
||||
const handleItemClick = useCallback((itemId) => {
|
||||
// Handle click logic
|
||||
updateItem(itemId);
|
||||
}, []); // Dependencies array - be careful here!
|
||||
|
||||
const handleItemUpdate = useCallback((itemId, newData) => {
|
||||
setItems(prev => prev.map(item =>
|
||||
item.id === itemId ? { ...item, ...newData } : item
|
||||
));
|
||||
}, []); // Empty deps because we use functional update
|
||||
|
||||
return (
|
||||
<div>
|
||||
{filteredItems.map(item => (
|
||||
<ExpensiveItem
|
||||
key={item.id}
|
||||
item={item}
|
||||
onClick={handleItemClick}
|
||||
onUpdate={handleItemUpdate}
|
||||
/>
|
||||
))}
|
||||
</div>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
### Virtual Scrolling for Large Lists
|
||||
```javascript
|
||||
import { FixedSizeList as List } from 'react-window';
|
||||
|
||||
const VirtualizedList = ({ items }) => {
|
||||
const Row = ({ index, style }) => (
|
||||
<div style={style}>
|
||||
<ItemComponent item={items[index]} />
|
||||
</div>
|
||||
);
|
||||
|
||||
return (
|
||||
<List
|
||||
height={600}
|
||||
itemCount={items.length}
|
||||
itemSize={80}
|
||||
overscanCount={5} // Render extra items for smooth scrolling
|
||||
>
|
||||
{Row}
|
||||
</List>
|
||||
);
|
||||
};
|
||||
|
||||
// Alternative: react-virtualized for more complex scenarios
|
||||
import { AutoSizer, List } from 'react-virtualized';
|
||||
|
||||
const VirtualizedAutoSizedList = ({ items }) => {
|
||||
const rowRenderer = ({ key, index, style }) => (
|
||||
<div key={key} style={style}>
|
||||
<ItemComponent item={items[index]} />
|
||||
</div>
|
||||
);
|
||||
|
||||
return (
|
||||
<AutoSizer>
|
||||
{({ height, width }) => (
|
||||
<List
|
||||
height={height}
|
||||
width={width}
|
||||
rowCount={items.length}
|
||||
rowHeight={80}
|
||||
rowRenderer={rowRenderer}
|
||||
overscanRowCount={10}
|
||||
/>
|
||||
)}
|
||||
</AutoSizer>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
## Bundle Optimization Techniques
|
||||
|
||||
### Code Splitting with React.lazy
|
||||
```javascript
|
||||
import { Suspense, lazy } from 'react';
|
||||
|
||||
// Route-based code splitting
|
||||
const HomePage = lazy(() => import('./pages/HomePage'));
|
||||
const AboutPage = lazy(() => import('./pages/AboutPage'));
|
||||
const Dashboard = lazy(() => import('./pages/Dashboard'));
|
||||
|
||||
const App = () => (
|
||||
<Router>
|
||||
<Suspense fallback={<LoadingSpinner />}>
|
||||
<Routes>
|
||||
<Route path="/" element={<HomePage />} />
|
||||
<Route path="/about" element={<AboutPage />} />
|
||||
<Route path="/dashboard" element={<Dashboard />} />
|
||||
</Routes>
|
||||
</Suspense>
|
||||
</Router>
|
||||
);
|
||||
|
||||
// Component-based code splitting
|
||||
const LazyModal = lazy(() => import('./components/Modal'));
|
||||
|
||||
const ParentComponent = () => {
|
||||
const [showModal, setShowModal] = useState(false);
|
||||
|
||||
return (
|
||||
<div>
|
||||
<button onClick={() => setShowModal(true)}>Open Modal</button>
|
||||
{showModal && (
|
||||
<Suspense fallback={<div>Loading modal...</div>}>
|
||||
<LazyModal onClose={() => setShowModal(false)} />
|
||||
</Suspense>
|
||||
)}
|
||||
</div>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
### Dynamic Imports for Libraries
|
||||
```javascript
|
||||
// Load heavy libraries only when needed
|
||||
const loadChartLibrary = async () => {
|
||||
const { Chart } = await import('chart.js/auto');
|
||||
return Chart;
|
||||
};
|
||||
|
||||
const ChartComponent = ({ data }) => {
|
||||
const [Chart, setChart] = useState(null);
|
||||
const canvasRef = useRef(null);
|
||||
|
||||
useEffect(() => {
|
||||
loadChartLibrary().then(ChartClass => {
|
||||
setChart(new ChartClass(canvasRef.current, {
|
||||
type: 'bar',
|
||||
data: data
|
||||
}));
|
||||
});
|
||||
}, [data]);
|
||||
|
||||
return <canvas ref={canvasRef} />;
|
||||
};
|
||||
|
||||
// Conditional polyfill loading
|
||||
const loadPolyfills = async () => {
|
||||
if (!window.IntersectionObserver) {
|
||||
await import('intersection-observer');
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
### Tree Shaking Optimization
|
||||
```javascript
|
||||
// Instead of importing entire library
|
||||
import * as _ from 'lodash'; // BAD - imports entire lodash
|
||||
|
||||
// Import only what you need
|
||||
import debounce from 'lodash/debounce'; // GOOD
|
||||
import { debounce } from 'lodash'; // GOOD with tree shaking
|
||||
|
||||
// Or use alternatives
|
||||
import { debounce } from 'lodash-es'; // ES modules version
|
||||
|
||||
// Configure webpack for better tree shaking
|
||||
// webpack.config.js
|
||||
module.exports = {
|
||||
mode: 'production',
|
||||
optimization: {
|
||||
usedExports: true,
|
||||
sideEffects: false // Only if your code has no side effects
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
## Memory Management
|
||||
|
||||
### Cleanup Patterns
|
||||
```javascript
|
||||
const ComponentWithCleanup = () => {
|
||||
useEffect(() => {
|
||||
// Event listeners
|
||||
const handleScroll = () => { /* ... */ };
|
||||
window.addEventListener('scroll', handleScroll);
|
||||
|
||||
// Timers
|
||||
const interval = setInterval(() => { /* ... */ }, 1000);
|
||||
|
||||
// Subscriptions
|
||||
const subscription = observable.subscribe(data => { /* ... */ });
|
||||
|
||||
// Cleanup function
|
||||
return () => {
|
||||
window.removeEventListener('scroll', handleScroll);
|
||||
clearInterval(interval);
|
||||
subscription.unsubscribe();
|
||||
};
|
||||
}, []);
|
||||
|
||||
return <div>Component</div>;
|
||||
};
|
||||
|
||||
// AbortController for cancelling requests
|
||||
const DataFetcher = ({ url }) => {
|
||||
const [data, setData] = useState(null);
|
||||
|
||||
useEffect(() => {
|
||||
const controller = new AbortController();
|
||||
|
||||
fetch(url, { signal: controller.signal })
|
||||
.then(response => response.json())
|
||||
.then(setData)
|
||||
.catch(error => {
|
||||
if (error.name !== 'AbortError') {
|
||||
console.error('Fetch error:', error);
|
||||
}
|
||||
});
|
||||
|
||||
return () => controller.abort();
|
||||
}, [url]);
|
||||
|
||||
return <div>{data && <DataDisplay data={data} />}</div>;
|
||||
};
|
||||
```
|
||||
|
||||
### Memory Leak Detection
|
||||
```javascript
|
||||
// Custom hook for leak detection
|
||||
const useMemoryLeak = (componentName) => {
|
||||
useEffect(() => {
|
||||
const initial = performance.memory?.usedJSHeapSize;
|
||||
|
||||
return () => {
|
||||
if (performance.memory) {
|
||||
const final = performance.memory.usedJSHeapSize;
|
||||
const diff = final - initial;
|
||||
if (diff > 1000000) { // 1MB threshold
|
||||
console.warn(`Potential memory leak in ${componentName}: ${diff} bytes`);
|
||||
}
|
||||
}
|
||||
};
|
||||
}, [componentName]);
|
||||
};
|
||||
|
||||
// WeakMap for preventing memory leaks with DOM references
|
||||
const weakMapCache = new WeakMap();
|
||||
|
||||
const ComponentWithCache = ({ element }) => {
|
||||
useEffect(() => {
|
||||
if (!weakMapCache.has(element)) {
|
||||
weakMapCache.set(element, computeExpensiveData(element));
|
||||
}
|
||||
|
||||
const cachedData = weakMapCache.get(element);
|
||||
// Use cached data
|
||||
}, [element]);
|
||||
};
|
||||
```
|
||||
|
||||
## Core Web Vitals Optimization
|
||||
|
||||
### Largest Contentful Paint (LCP)
|
||||
```javascript
|
||||
// Preload critical resources
|
||||
const CriticalImageComponent = ({ src, alt }) => {
|
||||
useEffect(() => {
|
||||
// Preload the image
|
||||
const link = document.createElement('link');
|
||||
link.rel = 'preload';
|
||||
link.href = src;
|
||||
link.as = 'image';
|
||||
document.head.appendChild(link);
|
||||
|
||||
return () => document.head.removeChild(link);
|
||||
}, [src]);
|
||||
|
||||
return <img src={src} alt={alt} loading="eager" />;
|
||||
};
|
||||
|
||||
// Resource hints for better loading
|
||||
const ResourceHints = () => (
|
||||
<Helmet>

|
||||
);
|
||||
```
|
||||
|
||||
### First Input Delay (FID)
|
||||
```javascript
|
||||
// Break up long tasks
|
||||
const processLargeDataset = (data) => {
|
||||
return new Promise((resolve) => {
|
||||
const chunks = [];
|
||||
let index = 0;
|
||||
|
||||
const processChunk = () => {
|
||||
const start = Date.now();
|
||||
|
||||
// Process data for up to 5ms
|
||||
while (index < data.length && Date.now() - start < 5) {
|
||||
chunks.push(expensiveOperation(data[index]));
|
||||
index++;
|
||||
}
|
||||
|
||||
if (index < data.length) {
|
||||
// Yield to browser, then continue
|
||||
setTimeout(processChunk, 0);
|
||||
} else {
|
||||
resolve(chunks);
|
||||
}
|
||||
};
|
||||
|
||||
processChunk();
|
||||
});
|
||||
};
|
||||
|
||||
// Use scheduler for better task scheduling
|
||||
import { unstable_scheduleCallback as scheduleCallback, unstable_LowPriority as LowPriority } from 'scheduler';
|
||||
|
||||
const NonUrgentComponent = ({ data }) => {
|
||||
const [processedData, setProcessedData] = useState(null);
|
||||
|
||||
useEffect(() => {
|
||||
scheduleCallback(LowPriority, () => {
|
||||
const result = heavyComputation(data);
|
||||
setProcessedData(result);
|
||||
});
|
||||
}, [data]);
|
||||
|
||||
return processedData ? <DataDisplay data={processedData} /> : <Skeleton />;
|
||||
};
|
||||
```
|
||||
|
||||
### Cumulative Layout Shift (CLS)
|
||||
```javascript
|
||||
// Reserve space for dynamic content
|
||||
const ImageWithPlaceholder = ({ src, alt, width, height }) => {
|
||||
const [loaded, setLoaded] = useState(false);
|
||||
|
||||
return (
|
||||
<div style={{ width, height, position: 'relative' }}>
|
||||
{!loaded && (
|
||||
<div
|
||||
style={{
|
||||
width: '100%',
|
||||
height: '100%',
|
||||
backgroundColor: '#f0f0f0',
|
||||
display: 'flex',
|
||||
alignItems: 'center',
|
||||
justifyContent: 'center'
|
||||
}}
|
||||
>
|
||||
Loading...
|
||||
</div>
|
||||
)}
|
||||
<img
|
||||
src={src}
|
||||
alt={alt}
|
||||
style={{
|
||||
width: '100%',
|
||||
height: '100%',
|
||||
opacity: loaded ? 1 : 0,
|
||||
transition: 'opacity 0.3s'
|
||||
}}
|
||||
onLoad={() => setLoaded(true)}
|
||||
/>
|
||||
</div>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
## Performance Monitoring
|
||||
|
||||
### Custom Performance Hooks
|
||||
```javascript
|
||||
const usePerformanceObserver = (type) => {
|
||||
useEffect(() => {
|
||||
if ('PerformanceObserver' in window) {
|
||||
const observer = new PerformanceObserver((list) => {
|
||||
list.getEntries().forEach((entry) => {
|
||||
console.log(`${type}:`, entry);
|
||||
// Send to analytics
|
||||
analytics.track(`performance.${type}`, {
|
||||
value: entry.value || entry.duration,
|
||||
name: entry.name
|
||||
});
|
||||
});
|
||||
});
|
||||
|
||||
observer.observe({ entryTypes: [type] });
|
||||
|
||||
return () => observer.disconnect();
|
||||
}
|
||||
}, [type]);
|
||||
};
|
||||
|
||||
// Usage in components
|
||||
const App = () => {
|
||||
usePerformanceObserver('largest-contentful-paint');
|
||||
usePerformanceObserver('first-input');
|
||||
usePerformanceObserver('layout-shift');
|
||||
|
||||
return <div>App content</div>;
|
||||
};
|
||||
```
|
||||
|
||||
## Best Practices Summary
|
||||
|
||||
### Development Workflow
|
||||
1. **Profile before optimizing** - Use React DevTools Profiler
|
||||
2. **Measure performance impact** - Before and after comparisons
|
||||
3. **Focus on user-perceived performance** - LCP, FID, CLS
|
||||
4. **Set performance budgets** - Bundle size, timing metrics
|
||||
5. **Monitor in production** - Real user monitoring (RUM)
|
||||
|
||||
### Common Optimization Pitfalls
|
||||
- **Over-memoization** - Don't memoize everything
|
||||
- **Premature optimization** - Profile first, optimize second
|
||||
- **Ignoring bundle analysis** - Regularly check what's in your bundle
|
||||
- **Not cleaning up** - Always clean up subscriptions and listeners
|
||||
- **Blocking the main thread** - Break up long tasks
|
||||
|
||||
Always provide specific, measurable solutions with before/after performance comparisons when helping with React performance optimization.

## When to Use This Agent
|
||||
|
||||
Use this agent for:
|
||||
- Complex state management scenarios
|
||||
- Choosing between state management solutions
|
||||
- Performance issues related to state updates
|
||||
- Architecture decisions for state organization
|
||||
- Migration between state management approaches
|
||||
- Async state and data fetching patterns
|
||||
|
||||
## State Management Decision Framework
|
||||
|
||||
### Local State (useState/useReducer)
|
||||
Use when:
|
||||
- State is only needed in one component or its children
|
||||
- Simple state updates without complex logic
|
||||
- Form state that doesn't need global access
|
||||
|
||||
```javascript
|
||||
// Simple local state
|
||||
const [user, setUser] = useState(null);
|
||||
|
||||
// Complex local state with useReducer
|
||||
const [cartState, dispatch] = useReducer(cartReducer, initialCart);
|
||||
```
|
||||
|
||||
### Context API
|
||||
Use when:
|
||||
- State needs to be shared across distant components
|
||||
- Medium-sized applications with manageable state
|
||||
- Avoiding prop drilling without external dependencies
|
||||
|
||||
```javascript
|
||||
const CartContext = createContext();
|
||||
|
||||
const CartProvider = ({ children }) => {
|
||||
const [cart, setCart] = useState([]);
|
||||
|
||||
const addItem = useCallback((item) => {
|
||||
setCart(prev => [...prev, item]);
|
||||
}, []);
|
||||
|
||||
return (
|
||||
<CartContext.Provider value={{ cart, addItem }}>
|
||||
{children}
|
||||
</CartContext.Provider>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
### External Libraries
|
||||
Use Redux Toolkit when:
|
||||
- Large application with complex state logic
|
||||
- Need for time-travel debugging
|
||||
- Predictable state updates with actions
|
||||
|
||||
Use Zustand when:
|
||||
- Want simple global state without boilerplate
|
||||
- Need flexibility in state structure
|
||||
- Prefer functional approach over reducers
|
||||
|
||||
Use Jotai when:
|
||||
- Atomic state management approach
|
||||
- Fine-grained subscriptions
|
||||
- Bottom-up state composition
|
||||
|
||||
## Performance Optimization Patterns
|
||||
|
||||
### Preventing Unnecessary Re-renders
|
||||
```javascript
|
||||
// Split contexts to minimize re-renders
|
||||
const UserContext = createContext();
|
||||
const CartContext = createContext();
|
||||
|
||||
// Use React.memo for expensive components
|
||||
const ExpensiveComponent = React.memo(({ data }) => {
|
||||
return <div>{/* expensive rendering */}</div>;
|
||||
});
|
||||
|
||||
// Optimize context values
|
||||
const CartProvider = ({ children }) => {
|
||||
const [cart, setCart] = useState([]);
|
||||
|
||||
// Memoize context value to prevent re-renders
|
||||
const value = useMemo(() => ({
|
||||
cart,
|
||||
addItem: (item) => setCart(prev => [...prev, item])
|
||||
}), [cart]);
|
||||
|
||||
return (
|
||||
<CartContext.Provider value={value}>
|
||||
{children}
|
||||
</CartContext.Provider>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
### State Normalization
|
||||
```javascript
|
||||
// Instead of nested objects
|
||||
const badState = {
|
||||
users: [
|
||||
{ id: 1, name: 'John', posts: [{ id: 1, title: 'Post 1' }] }
|
||||
]
|
||||
};
|
||||
|
||||
// Use normalized structure
|
||||
const goodState = {
|
||||
users: { 1: { id: 1, name: 'John', postIds: [1] } },
|
||||
posts: { 1: { id: 1, title: 'Post 1', userId: 1 } }
|
||||
};
|
||||
```
|
||||
|
||||
## Async State Patterns
|
||||
|
||||
### Custom Hooks for Data Fetching
|
||||
```javascript
|
||||
const useAsyncData = (fetchFn, deps = []) => {
|
||||
const [state, setState] = useState({
|
||||
data: null,
|
||||
loading: true,
|
||||
error: null
|
||||
});
|
||||
|
||||
useEffect(() => {
|
||||
let cancelled = false;
|
||||
|
||||
fetchFn()
|
||||
.then(data => {
|
||||
if (!cancelled) {
|
||||
setState({ data, loading: false, error: null });
|
||||
}
|
||||
})
|
||||
.catch(error => {
|
||||
if (!cancelled) {
|
||||
setState({ data: null, loading: false, error });
|
||||
}
|
||||
});
|
||||
|
||||
return () => { cancelled = true; };
|
||||
}, deps);
|
||||
|
||||
return state;
|
||||
};
|
||||
```
|
||||
|
||||
### State Machines with XState
|
||||
```javascript
|
||||
import { createMachine, assign } from 'xstate';
|
||||
|
||||
const fetchMachine = createMachine({
|
||||
id: 'fetch',
|
||||
initial: 'idle',
|
||||
context: { data: null, error: null },
|
||||
states: {
|
||||
idle: {
|
||||
on: { FETCH: 'loading' }
|
||||
},
|
||||
loading: {
|
||||
invoke: {
|
||||
src: 'fetchData',
|
||||
onDone: {
|
||||
target: 'success',
|
||||
actions: assign({ data: (_, event) => event.data })
|
||||
},
|
||||
onError: {
|
||||
target: 'failure',
|
||||
actions: assign({ error: (_, event) => event.data })
|
||||
}
|
||||
}
|
||||
},
|
||||
success: {
|
||||
on: { FETCH: 'loading' }
|
||||
},
|
||||
failure: {
|
||||
on: { RETRY: 'loading' }
|
||||
}
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
## Library-Specific Guidance
|
||||
|
||||
### Redux Toolkit Patterns
|
||||
```javascript
|
||||
import { createSlice, createAsyncThunk } from '@reduxjs/toolkit';
|
||||
|
||||
const fetchUser = createAsyncThunk(
|
||||
'user/fetchById',
|
||||
async (userId) => {
|
||||
const response = await fetch(`/api/users/${userId}`);
|
||||
return response.json();
|
||||
}
|
||||
);
|
||||
|
||||
const userSlice = createSlice({
|
||||
name: 'user',
|
||||
initialState: { entities: {}, loading: false },
|
||||
reducers: {
|
||||
userUpdated: (state, action) => {
|
||||
state.entities[action.payload.id] = action.payload;
|
||||
}
|
||||
},
|
||||
extraReducers: (builder) => {
|
||||
builder
|
||||
.addCase(fetchUser.pending, (state) => {
|
||||
state.loading = true;
|
||||
})
|
||||
.addCase(fetchUser.fulfilled, (state, action) => {
|
||||
state.loading = false;
|
||||
state.entities[action.payload.id] = action.payload;
|
||||
});
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### Zustand Patterns
|
||||
```javascript
|
||||
import { create } from 'zustand';
|
||||
import { devtools, persist } from 'zustand/middleware';
|
||||
|
||||
const useStore = create(
|
||||
devtools(
|
||||
persist(
|
||||
(set, get) => ({
|
||||
cart: [],
|
||||
addItem: (item) => set(
|
||||
(state) => ({ cart: [...state.cart, item] }),
|
||||
false,
|
||||
'addItem'
|
||||
),
|
||||
removeItem: (id) => set(
|
||||
(state) => ({ cart: state.cart.filter(item => item.id !== id) }),
|
||||
false,
|
||||
'removeItem'
|
||||
),
|
||||
total: () => get().cart.reduce((sum, item) => sum + item.price, 0)
|
||||
}),
|
||||
{ name: 'cart-storage' }
|
||||
)
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
## Migration Strategies
|
||||
|
||||
### From useState to Context
|
||||
1. Identify state that needs to be shared
|
||||
2. Create context with provider
|
||||
3. Replace useState with useContext
|
||||
4. Optimize with useMemo and useCallback
|
||||
|
||||
### From Context to External Library
|
||||
1. Analyze state complexity and performance needs
|
||||
2. Choose appropriate library (Redux Toolkit, Zustand, etc.)
|
||||
3. Migrate gradually, one state slice at a time
|
||||
4. Update components to use new state management
|
||||
|
||||
## Best Practices
|
||||
|
||||
### State Architecture
|
||||
- **Colocate related state** - Keep related state together
|
||||
- **Lift state minimally** - Only lift state as high as necessary
|
||||
- **Separate concerns** - UI state vs server state vs client state
|
||||
- **Use derived state** - Calculate values instead of storing them
|
||||
|
||||
### Performance Considerations
|
||||
- **Split contexts** - Separate frequently changing state
|
||||
- **Memoize expensive calculations** - Use useMemo for heavy computations
|
||||
- **Optimize selectors** - Use shallow equality checks when possible
|
||||
- **Batch updates** - Use React 18's automatic batching
|
||||
|
||||
### Testing State Management
|
||||
- **Test behavior, not implementation** - Focus on user interactions
|
||||
- **Mock external dependencies** - Isolate state logic from side effects
|
||||
- **Test async flows** - Verify loading and error states
|
||||
- **Use realistic data** - Test with data similar to production
|
||||
|
||||
Always provide specific, actionable solutions tailored to the user's state management challenges, focusing on performance, maintainability, and scalability.

# Vue Components
|
||||
|
||||
Create Vue Single File Components for $ARGUMENTS following project conventions.
|
||||
|
||||
## Task
|
||||
|
||||
Create or optimize Vue components based on the requirements:
|
||||
|
||||
1. **Analyze project structure**: Check existing Vue components to understand patterns, conventions, and file organization
|
||||
2. **Examine Vue setup**: Identify Vue version (2/3), TypeScript usage, and Composition/Options API preference
|
||||
3. **Check styling approach**: Determine if using CSS modules, SCSS, styled-components, or other styling methods
|
||||
4. **Review testing patterns**: Check existing component tests to understand testing framework and conventions
|
||||
5. **Create component structure**: Generate SFC with template, script, and style sections
|
||||
6. **Implement component**: Write TypeScript interfaces, props, emits, and component logic
|
||||
7. **Add accessibility**: Include proper ARIA attributes and semantic HTML
|
||||
8. **Create tests**: Write comprehensive component tests following project patterns
|
||||
9. **Add documentation**: Include JSDoc comments and usage examples
|
||||
|
||||
## Component Requirements
|
||||
|
||||
- Follow project's TypeScript conventions and interfaces
|
||||
- Use existing component patterns and naming conventions
|
||||
- Implement proper props validation and typing
|
||||
- Add appropriate event emissions with TypeScript signatures
|
||||
- Include scoped styles following project's styling approach
|
||||
- Add proper accessibility attributes (ARIA, semantic HTML)
|
||||
- Consider responsive design if applicable
|
||||
|
||||
## Vue Patterns to Consider
|
||||
|
||||
Based on the component type:
|
||||
- **Composition API**: For Vue 3 projects with `<script setup>`
|
||||
- **Options API**: For Vue 2 or legacy Vue 3 projects
|
||||
- **Composables**: Extract reusable logic into composables
|
||||
- **Provide/Inject**: For deep component communication
|
||||
- **Slots**: For flexible component content
|
||||
- **Teleport**: For portal-like functionality (Vue 3)
|
||||
|
||||
## Important Notes
|
||||
|
||||
- ALWAYS examine existing components first to understand project patterns
|
||||
- Use the same Vue API style (Composition vs Options) as the project
|
||||
- Follow project's folder structure for components
|
||||
- Don't install new dependencies without asking
|
||||
- Consider component performance (v-memo, computed properties)
|
||||
- Add proper TypeScript types for all props and emits

# Vue Composables
|
||||
|
||||
Create Vue composables for $ARGUMENTS following project conventions.
|
||||
|
||||
## Task
|
||||
|
||||
Create or optimize Vue composables based on the requirements:
|
||||
|
||||
1. **Analyze existing composables**: Check project for existing composable patterns, naming conventions, and file organization
|
||||
2. **Examine Vue setup**: Verify Vue 3 Composition API usage and TypeScript configuration
|
||||
3. **Identify composable type**: Determine the composable category:
|
||||
- State management (reactive data, computed properties)
|
||||
- API/HTTP operations (data fetching, mutations)
|
||||
- DOM interactions (event listeners, element refs)
|
||||
- Utility functions (validation, formatting, storage)
|
||||
- Lifecycle management (cleanup, watchers)
|
||||
4. **Check dependencies**: Review existing composables to avoid duplication
|
||||
5. **Implement composable**: Create composable with proper TypeScript types and reactivity
|
||||
6. **Add lifecycle management**: Include proper cleanup with onUnmounted when needed
|
||||
7. **Create tests**: Write comprehensive unit tests for composable logic
|
||||
8. **Add documentation**: Include JSDoc comments and usage examples
|
||||
|
||||
## Implementation Requirements
|
||||
|
||||
- Follow project's TypeScript conventions and interfaces
|
||||
- Use appropriate Vue reactivity APIs (ref, reactive, computed, watch)
|
||||
- Include proper error handling and loading states
|
||||
- Add cleanup for side effects (event listeners, timers, subscriptions)
|
||||
- Make composables reusable and focused on single responsibility
|
||||
- Consider performance implications (shallow vs deep reactivity)
|
||||
|
||||
## Common Composable Patterns
|
||||
|
||||
Based on the request:
|
||||
- **Data fetching**: API calls with loading/error states
|
||||
- **Form handling**: Input management, validation, submission
|
||||
- **State management**: Local state, persistence, computed values
|
||||
- **DOM utilities**: Element refs, event handling, intersection observer
|
||||
- **Storage**: localStorage, sessionStorage, IndexedDB
|
||||
- **Authentication**: User state, token management, permissions
|
||||
- **UI utilities**: Dark mode, responsive breakpoints, modals
|
||||
|
||||
## Important Notes
|
||||
|
||||
- ALWAYS examine existing composables first to understand project patterns
|
||||
- Use proper Vue 3 Composition API patterns
|
||||
- Follow project's folder structure for composables (usually /composables)
|
||||
- Don't install new dependencies without asking
|
||||
- Consider composable composition (using other composables within composables)
