Module logger

Sovereign node logging system for WayrApp platform.

This module provides a centralized, environment-aware logging solution built on Winston. It automatically adapts to serverless environments (Vercel, AWS Lambda, Netlify) by disabling file-based logging while maintaining console output. In traditional server environments, it provides both console and file-based logging with automatic log directory creation. The logger supports multiple log levels (error, warn, info, http, debug) with colorized console output and structured JSON file logging.

Example

// Basic logging usage
import { logger } from '@/shared/utils/logger';

logger.info('User authentication successful', { userId: '123', method: 'JWT' });
logger.warn('Rate limit approaching', { currentRequests: 95, limit: 100 });
logger.error('Database connection failed', { error: error.message, retryCount: 3 });
logger.debug('Cache hit', { key: 'user:123', ttl: 300 });

Example

// Environment-specific behavior
// In serverless environments (Vercel, Lambda, Netlify):
// - Only console logging is active
// - No file system operations
// - Structured JSON format for log aggregation

// In traditional server environments:
// - Console + file logging active
// - Automatic logs/ directory creation
// - Separate error.log and combined.log files

Example

// Configuration via environment variables
// LOG_LEVEL=debug (enables all log levels)
// LOG_LEVEL=info (default, enables info, warn, error)
// LOG_LEVEL=error (only error logs)

logger.debug('This appears only when LOG_LEVEL=debug');
logger.info('This appears when LOG_LEVEL=info or debug');
logger.error('This always appears unless LOG_LEVEL is disabled');
