Debug Store Types Proposal

Proposed type definitions and store patterns for advanced debugging capabilities in the Context-Action framework.

📋 Proposal Overview

This document proposes new type definitions and store patterns to support comprehensive debugging functionality, including state monitoring, error tracking, and performance analysis.

Proposed Type Definitions

Debug State Types

// Core debug state types
interface DebugState {
  isEnabled: boolean;
  level: 'minimal' | 'standard' | 'verbose';
  timestamp: number;
  sessionId: string;
}

interface ActionLog {
  id: string;
  actionType: string;
  timestamp: number;
  payload?: any;
  result?: any;
  duration?: number;
  error?: string;
}

interface ErrorEntry {
  id: string;
  timestamp: number;
  message: string;
  stack?: string;
  context?: Record<string, any>;
  severity: 'low' | 'medium' | 'high' | 'critical';
  resolved: boolean;
}

interface PerformanceMetric {
  id: string;
  operation: string;
  startTime: number;
  endTime: number;
  duration: number;
  memoryUsage?: number;
  metadata?: Record<string, any>;
}

interface StateSnapshot {
  id: string;
  timestamp: number;
  storeName: string;
  previousValue: any;
  currentValue: any;
  changeReason?: string;
}

Debug Store Interfaces

// Proposed debug store pattern
interface DebugStores {
  // Core debug configuration
  debugState: DebugState;
  
  // Action monitoring
  actionLog: ActionLog[];
  actionCount: Record<string, number>;
  
  // Error tracking
  errors: ErrorEntry[];
  errorCount: number;
  
  // Performance monitoring
  performanceMetrics: PerformanceMetric[];
  operationTimes: Record<string, number[]>;
  
  // State change tracking
  stateSnapshots: StateSnapshot[];
  storeSubscriptions: Record<string, number>;
  
  // Processing states
  isLogging: boolean;
  isProfilering: boolean;
  isRecording: boolean;
}

// Enhanced monitoring configuration
interface MonitoringConfig {
  maxLogEntries: number;
  maxErrorEntries: number;
  maxSnapshots: number;
  performanceThreshold: number;
  enableRealTimeAnalysis: boolean;
  filterPatterns: string[];
}

Debug Action Types

// Proposed debug action interfaces
interface DebugActions extends ActionPayloadMap {
  // Core debug control
  enableDebug: { level: DebugState['level'] };
  disableDebug: void;
  clearDebugData: void;
  
  // Action monitoring
  logAction: { actionType: string; payload?: any; duration?: number };
  clearActionLog: void;
  exportActionLog: void;
  
  // Error handling
  recordError: { error: Error; context?: Record<string, any> };
  resolveError: { errorId: string };
  clearErrors: void;
  
  // Performance tracking
  startPerformanceTimer: { operation: string; metadata?: Record<string, any> };
  endPerformanceTimer: { operation: string };
  recordMetric: { metric: PerformanceMetric };
  
  // State monitoring
  captureStateSnapshot: { storeName: string; changeReason?: string };
  startStateRecording: void;
  stopStateRecording: void;
  
  // Analysis and export
  generateDebugReport: void;
  exportDebugData: { format: 'json' | 'csv' | 'html' };
}

Monitoring Utility Types

// Advanced monitoring types
interface StoreMonitor<T = any> {
  storeName: string;
  currentValue: T;
  previousValue?: T;
  changeCount: number;
  lastChanged: number;
  subscribers: number;
}

interface ActionMonitor {
  actionType: string;
  totalCalls: number;
  averageDuration: number;
  errorRate: number;
  lastCalled: number;
  successCount: number;
  errorCount: number;
}

interface DebugAnalytics {
  sessionDuration: number;
  totalActions: number;
  totalErrors: number;
  averageActionDuration: number;
  memoryUsage: number;
  storeChangeRate: number;
  errorRate: number;
}

Debug Context Types

// Proposed debug context pattern
interface DebugContextValue {
  // Core debug state
  isDebugMode: boolean;
  debugLevel: DebugState['level'];
  
  // Monitoring controls
  startMonitoring: (config?: Partial<MonitoringConfig>) => void;
  stopMonitoring: () => void;
  pauseMonitoring: () => void;
  
  // Data access
  getActionLog: () => ActionLog[];
  getErrors: () => ErrorEntry[];
  getPerformanceMetrics: () => PerformanceMetric[];
  getStateSnapshots: () => StateSnapshot[];
  
  // Analysis
  generateReport: () => DebugAnalytics;
  exportData: (format: 'json' | 'csv' | 'html') => string;
  
  // Cleanup
  clearAll: () => void;
  clearOldEntries: (olderThanMs: number) => void;
}

Proposed Store Patterns

Debug Store Configuration

// Complete debug store setup
const debugStoreConfig = {
  // Core debug state
  debugState: {
    isEnabled: false,
    level: 'standard' as const,
    timestamp: Date.now(),
    sessionId: crypto.randomUUID()
  },
  
  // Action monitoring
  actionLog: [] as ActionLog[],
  actionCount: {} as Record<string, number>,
  
  // Error tracking
  errors: [] as ErrorEntry[],
  errorCount: 0,
  
  // Performance monitoring
  performanceMetrics: [] as PerformanceMetric[],
  operationTimes: {} as Record<string, number[]>,
  
  // State change tracking
  stateSnapshots: [] as StateSnapshot[],
  storeSubscriptions: {} as Record<string, number>,
  
  // Processing states
  isLogging: false,
  isProfilering: false,
  isRecording: false
};

// Context creation with proposed pattern
const {
  Provider: DebugStoreProvider,
  useStore: useDebugStore,
  useStoreManager: useDebugStoreManager
} = createStoreContext('Debug', debugStoreConfig);

Debug Action Context

// Proposed debug action context
const {
  Provider: DebugActionProvider,
  useActionDispatch: useDebugDispatch,
  useActionHandler: useDebugHandler
} = createActionContext<DebugActions>('Debug');

Implementation Strategy

Phase 1: Basic Debug Types

1. Implement core debug state and action log types
2. Create basic debug store configuration
3. Add simple action and error logging

Phase 2: Advanced Monitoring

1. Add performance metric types and monitoring
2. Implement state snapshot functionality
3. Create debug analytics and reporting

Phase 3: Integration & Optimization

1. Integrate with existing store and action patterns
2. Add automated monitoring triggers
3. Optimize performance impact of debug features

Benefits

1. Type Safety: Full TypeScript support for debug operations
2. Modular Design: Debug features can be enabled/disabled as needed
3. Performance Monitoring: Built-in performance tracking capabilities
4. Error Analysis: Comprehensive error tracking and analysis
5. State Inspection: Deep visibility into store state changes
6. Export Capabilities: Multiple export formats for analysis

Compatibility

• ✅ Compatible with existing Action and Store patterns
• ✅ Does not modify core framework behavior
• ✅ Optional feature that can be enabled per context
• ✅ Follows established naming conventions
• ✅ Integrates with existing setup patterns
