Best Practices and Usage Patterns

This section collects guidelines, recommended patterns, and anti-patterns to help you get the most out of KIMU.

Best Practices

1. Intentional Modularity

   • Divide the interface into meaningful components
   • Load extensions only when needed
   • Maintain a clear separation of concerns

2. Functional Minimalism

   • Start with the bare essentials
   • Add features only when truly necessary
   • Prefer clarity over complexity

3. Mindful Design

   • Use space with intention
   • Create visual rhythm through consistency
   • Respect the user's attention

Anti-Patterns to Avoid

• Overloading the interface with non-essential features
• Replicating patterns from more complex frameworks
• Forcing KIMU into scenarios that require full enterprise features

Concrete Examples

🌟 Case Study: Interactive Museum System

// Example of a KIMU component for a museum display
@kimuComponent({
  name: 'museum-display',
  template: minimal`
    <div class="exhibit">
      <h2>${props.title}</h2>
      <media-player src="${props.content}"></media-player>
      <gesture-controls></gesture-controls>
    </div>
  `
})

🎯 Case Study: Minimal Dashboard

// Example of a dashboard component
@kimuComponent({
  name: 'data-view',
  template: minimal`
    <div class="dashboard">
      <real-time-chart></real-time-chart>
      <status-indicators></status-indicators>
    </div>
  `
})

🚀 Performance and Optimizations

Robust Error Handling

@KimuComponent({
    tag: 'reliable-component',
    name: 'Reliable Component',
    path: 'reliable-component'
})
export class ReliableComponent extends KimuComponentElement {
    
    // ✅ Custom error handling
    onError(error: Error): void {
        console.error(`Error in ${this.tagName}:`, error);
        
        // Report error to monitoring service
        this.reportToMonitoring(error);
        
        // Notify user with appropriate message
        this.showUserFriendlyMessage();
    }
    
    // ✅ Robust data validation
    getData(): Record<string, any> {
        try {
            const data = this.getDataUnsafe();
            return this.validateData(data);
        } catch (error) {
            console.warn('Fallback to default data:', error);
            return this.getDefaultData();
        }
    }
    
    private validateData(data: any): Record<string, any> {
        // Data schema validation
        if (!data || typeof data !== 'object') {
            throw new Error('Invalid data');
        }
        return data;
    }
}

Memory and Cache Management

// ✅ Optimal configuration for application type

// SPA with many components
KimuComponentElement.configureOptimizations({
    cacheMaxSize: 100,              // Extended cache
    enableTemplateCache: true,      // Active template cache
    enableAssetPreloading: true     // Strategic preloading
});

// Embedded app with limited memory
KimuComponentElement.configureOptimizations({
    cacheMaxSize: 25,               // Conservative cache
    enableTemplateCache: true,      // Keep basic cache
    enableAssetPreloading: false    // No preloading
});

// Real-time app with frequent updates
KimuComponentElement.configureOptimizations({
    enableRenderDebouncing: true,   // Critical debouncing
    cacheMaxSize: 50,               // Balanced cache
    enableErrorBoundaries: true     // Essential error isolation
});

Strategic Preloading

class AssetPreloadingStrategy {
    
    // ✅ User priority-based preloading
    static async preloadCriticalPath(userType: string) {
        const criticalAssets = this.getAssetsForUserType(userType);
        
        // Preload critical assets for specific user experience
        await KimuComponentElement.preloadAssets(criticalAssets);
    }
    
    // ✅ Lazy preloading for less used sections
    static async preloadOnDemand(section: string) {
        const sectionAssets = this.getAssetsForSection(section);
        
        // Preload only when user shows interest
        setTimeout(() => {
            KimuComponentElement.preloadAssets(sectionAssets);
        }, 2000); // Delay to avoid initial impact
    }
    
    private static getAssetsForUserType(userType: string): string[] {
        const assetMap = {
            'admin': [
                'extensions/admin-dashboard/view.html',
                'extensions/admin-dashboard/style.css',
                'extensions/user-management/view.html'
            ],
            'user': [
                'extensions/user-dashboard/view.html',
                'extensions/user-profile/view.html'
            ]
        };
        
        return assetMap[userType] || [];
    }
}

Monitoring and Debug

class PerformanceMonitor {
    
    // ✅ Optimization monitoring
    static logOptimizationStatus() {
        const settings = KimuComponentElement.getOptimizationSettings();
        
        console.group('🔧 KIMU Optimizations');
        console.table(settings);
        console.groupEnd();
    }
    
    // ✅ Component performance benchmark
    static measureComponentPerformance(component: KimuComponentElement) {
        const start = performance.now();
        
        component.refresh().then(() => {
            const duration = performance.now() - start;
            console.log(`📊 ${component.tagName} render: ${duration.toFixed(2)}ms`);
        });
    }
    
    // ✅ Cache health check
    static checkCacheHealth() {
        // Custom implementation for cache monitoring
        console.log('💾 Cache Status: OK');
    }
}

// Usage in development
if (process.env.NODE_ENV === 'development') {
    PerformanceMonitor.logOptimizationStatus();
    
    // Monitor every 30 seconds
    setInterval(() => {
        PerformanceMonitor.checkCacheHealth();
    }, 30000);
}
