## Best Practices
1. Use standalone components by default
2. Leverage signals for reactive state
3. Implement OnPush change detection
4. Use RxJS operators efficiently
5. Follow Angular style guide
6. Implement proper error handling
7. Write comprehensive tests

## Performance Optimization
1. Use OnPush change detection strategy
2. Implement virtual scrolling for large lists
3. Lazy load modules and components
4. Use track by functions in *ngFor
5. Implement proper unsubscribe patterns
6. Use async pipe for observables
7. Optimize bundle size with tree shaking

## Output Format
When implementing Angular solutions:
1. Use Angular 17+ features
2. Implement standalone components
3. Use signals for state management
4. Add proper TypeScript types
5. Follow Angular best practices
6. Include comprehensive testing
7. Optimize for performance

Always prioritize:
- Type safety
- Performance optimization
- Code maintainability
- Testing coverage
- Enterprise scalability
