🚀 Quick Start

1. React App Setup

import React from 'react';
import { 
  AIConfigProvider, 
  AIAssistant, 
  createQuickConfig 
} from '@cadcamfun/ai-service';

function App() {
  return (
    <AIConfigProvider autoValidate={true}>
      <div className="App">
        <h1>My CAD/CAM App</h1>
        
        {/* AI Assistant with configuration UI */}
        <AIAssistant 
          onElementsGenerated={(elements) => {
            console.log('Generated CAD elements:', elements);
          }}
          showConfigButton={true}
        />
      </div>
    </AIConfigProvider>
  );
}

export default App;

2. API Key Configuration

The package requires you to provide your own API keys. Users will see a configuration UI:

import { APIKeyConfig } from '@cadcamfun/ai-service';

<APIKeyConfig
  onConfigComplete={(config) => {
    console.log('✅ AI Service configured');
  }}
  onConfigError={(error) => {
    console.error('❌ Configuration failed:', error);
  }}
  showAdvanced={true}
/>

3. Programmatic Usage

import { aiService, aiConfigService } from '@cadcamfun/ai-service';

// Configure the service
aiConfigService.setConfig({
  anthropic: {
    apiKey: 'sk-ant-your-key-here',
    defaultModel: 'claude-sonnet-4-20250514'
  },
  openai: {
    apiKey: 'sk-your-key-here',
    defaultModel: 'gpt-4.1'
  }
});

// Generate CAD elements from text
const result = await aiService.textToCADElements({
  description: 'Create a mechanical bearing with 20mm inner diameter',
  style: 'engineering',
  complexity: 'moderate'
});

if (result.success) {
  console.log('Generated elements:', result.data);
}

🔑 API Keys Setup

Get Your API Keys

1. Anthropic Claude: Visit console.anthropic.com
2. OpenAI GPT: Visit platform.openai.com/api-keys
3. Mem0 (optional): Visit app.mem0.ai

Security Best Practices

⚠️ Important: This package requires client-side API key configuration. For production apps:

1. Never commit API keys to version control
2. Use environment variables for development
3. Consider server-side API routes for sensitive operations
4. Implement proper API key validation in your app

📚 Examples

Basic React Component

import { useAIConversation } from '@cadcamfun/ai-service';

function ChatComponent() {
  const { messages, sendMessage, isProcessing } = useAIConversation();
  
  const handleSend = async () => {
    await sendMessage('Create a simple cube');
  };

  return (
    <div>
      {messages.map(msg => (
        <div key={msg.id}>{msg.content}</div>
      ))}
      <button onClick={handleSend} disabled={isProcessing}>

Enhanced AI Service Package - New Features

🚀 Performance & Reliability Improvements

1. Enhanced Memory Manager (src/services/memoryManager.ts)

Advanced memory management with intelligent caching, compression, and automatic cleanup:

import { memoryManager, EnhancedMemoryManager } from '@cadcamfun/ai-service';

// Smart caching with priority levels
await memoryManager.set('key', data, 'high'); // high priority cache
const result = await memoryManager.get('key');

// Session management
await memoryManager.createSession('session-1', initialData);
await memoryManager.updateSession('session-1', newData);

// Get performance metrics
const metrics = memoryManager.getMetrics();
console.log(`Memory used: ${metrics.totalMemoryUsed / 1024 / 1024}MB`);

Features:

• LRU Caching with priority-based eviction
• Automatic compression for large data
• Session-specific memory tracking
• Predictive cleanup algorithms
• Memory usage monitoring and alerts

2. AI Service Circuit Breaker (src/services/circuitBreaker.ts)

Fault tolerance pattern for AI service calls with automatic failover:

import { aiServiceCircuitBreaker } from '@cadcamfun/ai-service';

// Execute with circuit breaker protection
const result = await aiServiceCircuitBreaker.executeWithCircuitBreaker(
  'openai-service',
  () => openai.chat.completions.create({...}),
  () => fallbackResponse() // Optional fallback
);

// Monitor service health
const status = aiServiceCircuitBreaker.getAllServicesStatus();
console.log('OpenAI Status:', status['openai-service']);

Features:

• Automatic failure detection (5 failures → circuit opens)
• Intelligent retry with exponential backoff
• Service health monitoring with metrics
• Fallback mechanism support
• Self-healing circuit recovery

3. Resource Monitor (src/services/resourceMonitor.ts)

Real-time resource monitoring with predictive alerts:

import { resourceMonitor } from '@cadcamfun/ai-service';

// Start monitoring
resourceMonitor.startMonitoring();

// Set up alerts
const unsubscribe = resourceMonitor.onAlert((alert) => {
  console.warn(`Alert: ${alert.message} (${alert.severity})`);
});

// Record AI operations
resourceMonitor.recordOperation(
  responseTime: 1500, // ms
  tokensUsed: 1000,
  cost: 0.02, // dollars
  hasError: false
);

// Get health overview
const health = resourceMonitor.getResourceHealth();
console.log('System health:', health.overall);

Features:

• CPU & Memory monitoring (browser & Node.js)
• Cost tracking per hour/operation
• Token usage monitoring
• Predictive alerts (trend analysis)
• Customizable limits and thresholds

4. Batch Processor (src/services/batchProcessor.ts)

High-performance batch processing for CAD operations with parallel execution:

import { batchProcessor } from '@cadcamfun/ai-service';

// Process CAD elements in parallel
const result = await batchProcessor.processCADElements(
  cadElements,
  'optimize', // 'validate' | 'transform' | 'optimize' | 'render'
  { maxConcurrency: 10 }
);

console.log(`Processed: ${result.successful.length}, Failed: ${result.failed.length}`);

// Custom batch processing
const customResult = await batchProcessor.processBatch(
  items,
  async (item) => await processItem(item),
  {
    priority: 'high',
    onProgress: (completed, total) => {
      console.log(`Progress: ${completed}/${total}`);
    }
  }
);

Features:

• Parallel processing with concurrency control
• Backpressure handling for large queues
• Priority-based scheduling (low/medium/high)
• Automatic retry with exponential backoff
• Progress tracking and error handling
• CAD-specific operations (validate, transform, optimize, render)

});

// Set up resource alerts
resourceMonitor.onAlert((alert) => {
  if (alert.severity === 'critical') {
    console.error('Critical resource alert:', alert.message);
    // Trigger emergency cleanup
    memoryManager.optimizeMemory();
  }

  return aiServiceCircuitBreaker.executeWithCircuitBreaker(
    'anthropic-claude',
    () => aiService.generateResponse(prompt),
    () => ({ content: 'Service temporarily unavailable' })
  );
}

CAD Processing Pipeline

// Batch process CAD elements with monitoring
async function processCADProject(elements: CADElement[]) {
  const startTime = Date.now();
  
  try {
    // Validate all elements first
    const validationResult = await batchProcessor.processCADElements(
      elements, 
      'validate',
      { priority: 'high' }
    );
    
    // Filter valid elements
    const validElements = validationResult.successful
      .filter(result => result.isValid)
      .map(result => result.element);
    
    // Optimize valid elements
    const optimizationResult = await batchProcessor.processCADElements(
      validElements,
      'optimize',
      {
        priority: 'medium',
        onProgress: (completed, total) => {
          console.log(`Optimization: ${Math.round(completed/total*100)}%`);
        }
      }
    );
    
    // Record metrics
    const processingTime = Date.now() - startTime;
    resourceMonitor.recordOperation(
      processingTime,
      elements.length * 100, // estimated tokens
      elements.length * 0.001, // estimated cost
      optimizationResult.failed.length > 0
    );
    
    return {
      processed: optimizationResult.successful.length,
      failed: optimizationResult.failed.length,
      totalTime: processingTime
    };
    
  } catch (error) {
    console.error('CAD processing failed:', error);
    throw error;
  }
}
