🚀 Real-Time Performance Monitoring

Built-in Telemetry System

W3MSG SDK includes a comprehensive performance monitoring system that tracks:

import { sdkPerformance } from '@w3msg/sdk';

// Monitor wallet connections
const walletResult = await sdkPerformance.monitorWalletConnection(
  () => connectToMetaMask(),
  'MetaMask'
);

// Monitor message sending
const messageResult = await sdkPerformance.monitorMessageSend(
  () => sdk.send({ to: recipient, content: 'Hello!' }),
  'XMTP',
  1024 // message size in bytes
);

// Monitor VC verification
const vcResult = await sdkPerformance.monitorVCVerification(
  () => sdk.verifyCredential(credential),
  'PolygonID',
  3 // number of credentials
);

Performance Reports

Get comprehensive performance insights:

const report = sdkPerformance.getPerformanceReport();

console.log('Performance Summary:', {
  totalOperations: report.summary.totalOperations,
  successRate: `${(report.summary.successfulOperations / report.summary.totalOperations * 100).toFixed(1)}%`,
  averageTime: `${report.summary.averageDuration.toFixed(2)}ms`,
  slowestOperation: report.summary.slowestOperation?.operationName,
  fastestOperation: report.summary.fastestOperation?.operationName
});

Memory Usage Tracking

Monitor memory consumption across different environments:

// Memory tracking is automatic
const operations = sdkPerformance.getAllOperationTelemetry();

operations.forEach(op => {
  if (op.memoryBefore && op.memoryAfter) {
    const memoryDiff = op.memoryAfter.heapUsed - op.memoryBefore.heapUsed;
    console.log(`${op.operationName}: ${(memoryDiff / 1024 / 1024).toFixed(2)}MB`);
  }
});

⚡ Bundle Optimization

Tree-Shaking Strategy

W3MSG SDK uses advanced tree-shaking to minimize bundle size:

// Import only what you need - tree-shaking eliminates unused code
import { 
  W3MSGSDK,           // Core SDK (required)
  Result,             // Functional types (5KB)
  sdkPerformance,     // Performance monitoring (3KB)
  BrowserTestRunner   // Browser testing (4KB) - only if needed
} from '@w3msg/sdk';

// Protocol-specific imports are lazy-loaded
// XMTP: loaded only when used (~13KB chunk)
// Push: loaded only when used (~16KB chunk)

Code Splitting Analysis

Our intelligent code splitting creates optimized chunks:

# Generate bundle analysis
npm run build:analyze

# View detailed breakdown
open bundle-analysis.html

Chunk Strategy:

• Core SDK (20KB): Essential functionality
• XMTP Protocol (13KB): Loaded when XMTP is used
• Push Protocol (16KB): Loaded when Push is used
• Async Utilities (10KB): Timeout/retry logic
• Error Handling (16KB): Advanced error patterns
• Performance Utils (8KB): Telemetry and monitoring

Bundle Size Monitoring

Automated CI checks ensure bundle size stays optimized:

# .github/workflows/performance-monitoring.yml
- name: Bundle size check
  run: |
    ESM_SIZE=$(stat -c%s "dist/index.esm.js")
    if [ $ESM_SIZE -gt 10240 ]; then  # 10KB threshold
      echo "❌ ESM bundle exceeded 10KB limit"
      exit 1
    fi

🧪 Performance Testing

Browser Compatibility Testing

Test performance across different environments:

import { BrowserTestRunner, CapabilityTesting } from '@w3msg/sdk';

// Run comprehensive compatibility test
const report = await BrowserTestRunner.runCompatibilityTest();

console.log('Browser Performance:', {
  overallScore: report.performance.overallScore,
  criticalIssues: report.performance.criticalIssues,
  recommendations: report.performance.recommendations
});

// Test specific capabilities
const capabilities = await CapabilityTesting.runCapabilityTests();
const performanceCapabilities = capabilities.filter(cap => cap.performance);

performanceCapabilities.forEach(cap => {
  console.log(`${cap.feature}: ${cap.performance?.toFixed(2)}ms`);
});

Memory Usage Patterns

Monitor memory efficiency:

// Automatic memory snapshots during operations
const memoryReport = {
  walletConnection: '2.3MB increase',
  messageVerification: '1.8MB increase', 
  protocolSwitching: '0.5MB increase'
};

// Memory is cleaned up automatically due to functional patterns

Performance Regression Testing

Continuous performance monitoring in CI:

# Performance benchmarks
npm run test:performance

# Expected output:
# ✅ SDK Import: 12.34ms (target: <50ms)
# ✅ Wallet Connection: 234ms (target: <500ms)
# ✅ Message Send: 156ms (target: <300ms)
# ✅ Bundle Size: 6.58KB (target: <10KB)
# 🎯 Performance Score: 95/100

🔧 Performance Optimization Techniques

1. Functional Programming Benefits

Our functional architecture provides inherent performance benefits:

// Pure functions enable better optimization
const processMessage = (message: Message): ProcessedMessage => ({
  ...message,
  id: crypto.randomUUID(),
  timestamp: Date.now(),
  processed: true
});

// Immutable operations prevent memory leaks
const updateConfig = (current: Config, updates: Partial<Config>): Config => ({
  ...current,
  ...updates
});

// Higher-order functions enable code reuse
const withCaching = <T extends unknown[], R>(
  fn: (...args: T) => R,
  cacheKey: (...args: T) => string
) => {
  const cache = new Map<string, R>();
  return (...args: T): R => {
    const key = cacheKey(...args);
    if (cache.has(key)) return cache.get(key)!;
    
    const result = fn(...args);
    cache.set(key, result);
    return result;
  };
};

2. Async Optimization Patterns

Modern async patterns for better performance:

// Parallel operations with resilience
import { parallelWithResilience } from '@w3msg/sdk';

const results = await parallelWithResilience([
  () => sdk.connect(),
  () => sdk.loadProtocols(),
  () => sdk.initializeVC()
], {
  timeout: 10000,
  maxAttempts: 2
});

// Debounced operations to prevent excessive calls
import { debounceAsync } from '@w3msg/sdk';

const debouncedSearch = debounceAsync(
  (query: string) => sdk.searchMessages(query),
  500 // 500ms delay
);

3. Memory Management

Efficient memory usage through functional patterns:

// Immutable state updates prevent memory leaks
const updateState = (state: AppState, action: Action): AppState => {
  switch (action.type) {
    case 'SET_MESSAGES':
      return { ...state, messages: action.payload };
    case 'ADD_MESSAGE':
      return { 
        ...state, 
        messages: [...state.messages, action.payload] 
      };
    default:
      return state;
  }
};

// Weak references for cleanup
const messageCache = new WeakMap<MessageProtocol, CacheData>();

📈 Performance Best Practices

1. Bundle Size Optimization

// ✅ Good: Tree-shakable imports
import { Result, Either } from '@w3msg/sdk';

// ❌ Avoid: Full SDK import when only specific utilities needed
import * as W3MSG from '@w3msg/sdk'; // Imports everything

// ✅ Good: Conditional imports for optional features
const loadXMTP = () => import('@w3msg/sdk/xmtp');
const loadPush = () => import('@w3msg/sdk/push');

2. Runtime Performance

// ✅ Good: Use Result types for error handling
const sendMessage = async (message: Message): Promise<Result<Receipt, Error>> => {
  return Result.fromAsync(() => protocol.send(message));
};

// ✅ Good: Use performance monitoring for critical operations
const monitoredSend = sdkPerformance.monitorMessageSend(
  () => sendMessage(message),
  'XMTP',
  message.content.length
);

// ✅ Good: Implement proper caching strategies
const cachedVerification = withCaching(
  (credential: VC) => verifyCredential(credential),
  (vc) => vc.id
);

3. Memory Optimization

// ✅ Good: Use functional patterns to prevent leaks
const processMessages = (messages: readonly Message[]): readonly ProcessedMessage[] =>
  messages.map(msg => ({ ...msg, processed: true }));

// ✅ Good: Clean up event listeners properly
const cleanup = sdk.on('message', handler);
// Later: cleanup(); // Removes listener and prevents memory leaks

🎯 Performance Monitoring in Production

Real-Time Metrics

Monitor SDK performance in production applications:

// Set up performance monitoring
sdkPerformance.recordUXMetric('app_start', Date.now(), 'loading');
sdkPerformance.recordUXMetric('first_message', Date.now(), 'interactivity');

// Get periodic reports
setInterval(() => {
  const report = sdkPerformance.getPerformanceReport();
  
  // Send to your analytics service
  analytics.track('SDK_Performance', {
    averageOperationTime: report.summary.averageDuration,
    successRate: report.summary.successfulOperations / report.summary.totalOperations,
    memoryUsage: getCurrentMemoryUsage()
  });
}, 60000); // Every minute

Performance Alerts

Set up alerts for performance degradation:

const performanceGuards = {
  slowOperation: (duration: number) => duration > 1000,
  highMemoryUsage: (usage: number) => usage > 10 * 1024 * 1024, // 10MB
  lowSuccessRate: (rate: number) => rate < 0.95 // 95%
};

// Monitor and alert
const report = sdkPerformance.getPerformanceReport();
if (performanceGuards.slowOperation(report.summary.averageDuration)) {
  console.warn('Performance degradation detected');
  // Send alert to monitoring service
}

🔍 Debugging Performance Issues

Performance Profiling

Use built-in profiling tools:

// Enable detailed performance logging
const sdk = new W3MSGSDK({
  enableLogging: true,
  performanceLogging: true,  // Detailed timing logs
  memoryProfiling: true      // Memory usage tracking
});

// Check for performance bottlenecks
const report = sdkPerformance.getPerformanceReport();
const slowOperations = report.operations.filter(op => 
  op.duration && op.duration > 500
);

slowOperations.forEach(op => {
  console.log(`Slow operation: ${op.operationName} took ${op.duration}ms`);
});

Bundle Analysis

Identify bundle size issues:

# Generate detailed analysis
npm run build:analyze

# Check for large dependencies
npx webpack-bundle-analyzer dist/stats.json

# Identify tree-shaking issues
npx rollup-plugin-visualizer
