Develop Comprehensive Logging Module

[memplethee-lab]

Overview

Implement a structured logging module that provides consistent, configurable logging across the entire Alian Structure API.

Direction

This module should provide:

• Structured JSON logging for easy parsing and analysis
• Multiple log levels (DEBUG, INFO, WARN, ERROR, FATAL)
• Environment-aware log output configuration
• Integration with external logging services (e.g., ELK, CloudWatch)
• Request/response logging middleware
• Performance metric logging
• Error stack trace capture and formatting

Implementation Details

The logging module should use a proven logging library (Winston or similar) and provide a centralized logger factory. It should automatically include contextual information like request IDs, timestamps, and service identifiers.

Acceptance Criteria

• Logger factory provides consistent logger instances across the application
• All logs output in structured JSON format by default
• Log level configuration works per-environment
• Request middleware logs HTTP method, path, status, and response time
• Error logs include full stack traces and context
• Performance metrics are logged for slow operations (>1 second)
• External logging service integration is tested
• Sensitive data (passwords, tokens) is never logged
• Logging module tests verify output format and filtering

Hi! I'd like to work on this issue.

I have experience building production-grade logging systems using structured JSON logging with libraries such as Winston, including centralized logger factories, request/response logging middleware, environment-based log level configuration, performance monitoring, and integrations with external logging platforms. I'll ensure sensitive information is properly redacted, implement comprehensive test coverage, and keep the module configurable and production-ready.

Could you please assign this issue to me? Thank you!
