📊 Logging

The application uses structured logging with separate log files:

• Application Logs: logs/app.log - Main application events
• Access Logs: logs/access.log - HTTP request/response logs
• Database Logs: logs/database.log - Database queries and operations

Log Configuration

Logs are configured via environment variables:

• LOG_LEVEL: debug, info, warn, error (default: info)
• LOG_FORMAT: json, console (default: json)

🔒 Environment Configuration

Copy .env.example to .env and configure:

# Server Configuration
SERVER_PORT=8080
SERVER_HOST=localhost
SERVER_ENVIRONMENT=development

# Database Configuration
DATABASE_HOST=localhost
DATABASE_PORT=5432
DATABASE_USER=samurai
DATABASE_PASSWORD=samurai_password
DATABASE_NAME=samurai_db
DATABASE_SSL_MODE=disable

# Authentication
JWT_SECRET=your-jwt-secret-here
JWT_EXPIRY=24h

# Logging
LOG_LEVEL=info
LOG_FORMAT=json
