Documentation: utils / logging
Purpose:
Implements a logging system combining Winston, file logs, SQLite transport, and console patching with a custom 'security' level.
Lifecycle Role:
Global utility during request/response lifecycle and runtime.
Dependencies:
Upstream:
- winston
- daily rotating file logs
- SQLite transport
- console patch
Downstream:
- all modules requiring logging
Data Flow:
Inputs:
Log calls from application modules.
Outputs:
Persisted logs to disk, database, console.
Side Effects:
Disk and DB I/O operations.
Performance and Scalability:
Bottlenecks:
- Disk full or permission issues
- Synchronous or heavy logging load
- Log flooding under high volume
Concurrency:
None
Security and Stability:
Validation:
Log content must be sanitized to avoid secret leaks.
Vulnerabilities:
- Logging sensitive information
Architecture Assessment:
Coupling:
Loosely coupled via shared utility usage.
Abstraction:
Provides centralized logging abstraction.
Recommendations:
- Use asynchronous or buffered logging
- Add sensitive data redaction
- Enforce aggressive log rotation
- Secure log file permissions
