🚀 Quick Start¶

Basic Configuration Setup¶

import { ConfigManager } from "@juspay/neurolink/config";

// Initialize config manager
const configManager = new ConfigManager();

// Update configuration (automatic backup created)
await configManager.updateConfig({
  providers: {
    google: { enabled: true, model: "gemini-2.5-pro" },
    openai: { enabled: true, model: "gpt-4o" },
  },
  performance: {
    timeout: 30000,
    retries: 3,
  },
});
// ✅ Backup created: .neurolink.backups/neurolink-config-2025-01-07T10-30-00.js

Environment Configuration¶

# Enable automatic backups
NEUROLINK_BACKUP_ENABLED=true
NEUROLINK_BACKUP_RETENTION=30
NEUROLINK_BACKUP_DIRECTORY=.neurolink.backups

# Validation settings
NEUROLINK_VALIDATION_STRICT=false
NEUROLINK_VALIDATION_WARNINGS=true

# Provider monitoring
NEUROLINK_PROVIDER_STATUS_CHECK=true
NEUROLINK_PROVIDER_TIMEOUT=30000

📋 Configuration Structure¶

NeuroLinkConfig Interface¶

interface NeuroLinkConfig {
  providers: ProviderConfig; // AI provider settings
  performance: PerformanceConfig; // Performance optimization
  analytics: AnalyticsConfig; // Analytics configuration
  backup: BackupConfig; // Backup system settings
  validation: ValidationConfig; // Validation rules
}

Provider Configuration¶

interface ProviderConfig {
  google?: {
    enabled: boolean;
    model?: string;
    apiKey?: string;
    timeout?: number;
  };
  openai?: {
    enabled: boolean;
    model?: string;
    apiKey?: string;
    timeout?: number;
  };
  // ... other providers
}

Performance Configuration¶

interface PerformanceConfig {
  timeout: number; // Default timeout (ms)
  retries: number; // Default retry count
  cacheEnabled: boolean; // Enable execution caching
  cacheTTL: number; // Cache TTL (seconds)
  concurrency: number; // Max concurrent operations
}

🔄 Automatic Backup System¶

How It Works¶

Before Update: Config manager creates timestamped backup
Update Attempt: Apply new configuration
Validation: Validate new configuration
Success/Failure: Keep new config or auto-restore from backup

Backup File Structure¶

.neurolink.backups/
├── neurolink-config-2025-01-07T10-30-00.js    # Timestamped backup
├── neurolink-config-2025-01-07T11-15-30.js    # Another backup
├── metadata.json                               # Backup metadata
└── .backup-index                              # Backup index file

Backup Metadata¶

interface BackupMetadata {
  timestamp: string;
  hash: string; // SHA-256 hash
  size: number; // File size in bytes
  reason: string; // Reason for backup
  version: string; // Config version
  environment: string; // Environment context
  user?: string; // User who made change
}

Manual Backup Operations¶

// Create manual backup
const backupPath = await configManager.createBackup("manual-backup");
console.log(`Backup created: ${backupPath}`);

// List all backups
const backups = await configManager.listBackups();
console.log("Available backups:", backups);

// Restore from specific backup
await configManager.restoreFromBackup(
  "neurolink-config-2025-01-07T10-30-00.js",
);

✅ Configuration Validation¶

Validation Process¶

Schema Validation: Check against TypeScript interfaces
Provider Validation: Verify provider configurations
Dependency Validation: Check inter-config dependencies
Performance Validation: Validate performance settings
Security Validation: Check for security issues

Validation Examples¶

// Validate current config
const validation = await configManager.validateConfig();

if (!validation.isValid) {
  console.log("Validation errors:", validation.errors);
  console.log("Suggestions:", validation.suggestions);
}

// Validate before update
await configManager.updateConfig(newConfig, {
  validateBeforeUpdate: true,
  onValidationError: (errors) => {
    console.log("Validation failed:", errors);
  },
});

Common Validation Errors¶

// Example validation results
{
  isValid: false,
  errors: [
    {
      field: 'providers.google.model',
      message: 'Model "gemini-pro-deprecated" is deprecated',
      severity: 'warning',
      suggestion: 'Use "gemini-2.5-pro" instead'
    },
    {
      field: 'performance.timeout',
      message: 'Timeout value too low (< 1000ms)',
      severity: 'error',
      suggestion: 'Use timeout >= 1000ms for reliable operation'
    }
  ],
  suggestions: [
    'Consider enabling caching for better performance',
    'Add fallback providers for reliability'
  ]
}

🛠️ Advanced Configuration¶

Update Strategies¶

// Replace entire config
await configManager.updateConfig(newConfig, {
  mergeStrategy: "replace",
});

// Merge with existing config
await configManager.updateConfig(partialConfig, {
  mergeStrategy: "merge",
});

// Deep merge (preserves nested objects)
await configManager.updateConfig(partialConfig, {
  mergeStrategy: "deep-merge",
});

Custom Validation Rules¶

// Add custom validation
configManager.addValidator("performance", (config) => {
  if (config.performance.timeout < 5000) {
    return {
      isValid: false,
      message: "Timeout too low for production use",
      suggestion: "Use timeout >= 5000ms",
    };
  }
  return { isValid: true };
});

Event Handlers¶

// Listen for config events
configManager.on("configUpdated", (newConfig, oldConfig) => {
  console.log("Config updated:", { newConfig, oldConfig });
});

configManager.on("backupCreated", (backupPath) => {
  console.log("Backup created:", backupPath);
});

configManager.on("configRestored", (backupPath) => {
  console.log("Config restored from:", backupPath);
});

🚨 Error Recovery¶

Auto-Restore Process¶

Detection: Config update fails validation or causes errors
Identification: Find most recent valid backup
Restoration: Restore config from backup
Verification: Validate restored config
Notification: Log recovery action

Manual Recovery¶

// Check config health
const health = await configManager.checkHealth();
if (!health.isHealthy) {
  console.log("Config issues detected:", health.issues);

  // Restore from backup
  await configManager.autoRestore();
}

// Recovery from specific backup
try {
  await configManager.restoreFromBackup("backup-name.js");
  console.log("Successfully restored from backup");
} catch (error) {
  console.error("Restore failed:", error.message);
}

Recovery Scenarios¶

Corrupted Config: Auto-restore from last known good backup
Invalid Provider: Disable problematic provider, restore working config
Performance Issues: Restore previous performance settings
Validation Failures: Rollback to validated configuration

🧹 Cleanup & Maintenance¶

Automatic Cleanup¶

// Configure automatic cleanup
await configManager.updateConfig({
  backup: {
    retention: 30, // Keep backups for 30 days
    maxBackups: 100, // Keep max 100 backups
    autoCleanup: true, // Enable automatic cleanup
  },
});

Manual Cleanup¶

// Clean old backups
const cleaned = await configManager.cleanupBackups({
  olderThan: 30, // Days
  keepMinimum: 5, // Always keep at least 5 backups
});
console.log(`Cleaned ${cleaned.count} old backups`);

// Verify backup integrity
const verification = await configManager.verifyBackups();
console.log("Backup verification:", verification);

🔍 Monitoring & Diagnostics¶

Config Status¶

// Get config status
const status = await configManager.getStatus();
console.log("Config status:", {
  isValid: status.isValid,
  lastUpdated: status.lastUpdated,
  backupCount: status.backupCount,
  providerStatus: status.providers,
});

Provider Health Monitoring¶

// Check provider health
const providers = await configManager.checkProviderHealth();
providers.forEach((provider) => {
  console.log(`${provider.name}: ${provider.status}`);
  if (provider.status === "error") {
    console.log(`Error: ${provider.error}`);
  }
});

Performance Metrics¶

// Get performance metrics
const metrics = await configManager.getMetrics();
console.log("Config performance:", {
  updateTime: metrics.averageUpdateTime,
  validationTime: metrics.averageValidationTime,
  backupTime: metrics.averageBackupTime,
});

🚀 Best Practices¶

Configuration Management¶

Always Validate: Enable validation before updates
Use Backups: Keep automatic backups enabled
Monitor Health: Regular provider health checks
Version Control: Consider versioning config files
Environment Separation: Different configs for dev/prod

Performance Optimization¶

Cache Settings: Enable caching for frequently used configs
Timeout Tuning: Set appropriate timeouts for your use case
Provider Selection: Use fastest available providers
Cleanup Schedule: Regular backup cleanup

Security Considerations¶

API Key Management: Store API keys securely
Backup Encryption: Consider encrypting sensitive backups
Access Control: Limit config update permissions
Audit Logging: Log all config changes
