Implement: Replace all console logs in the backend services using the Winston npm library. No need to run tests for this first task.

Perfect! I have successfully replaced all console logs in the backend services with Winston logger. Let me provide a summary of what was accomplished:

Summary

I have successfully replaced all console.log statements in the backend services with the Winston logging library. Here's what was implemented:

1. Installed Winston (winston@3.17.0)

2. Created Logger Configuration (/home/daytona/workspace/lib/logger.ts)

• Development mode: Colorized console output with timestamps
• Production mode: JSON format with file logging to logs/error.log and logs/combined.log
• Log levels: error, warn, info, http, debug
• Structured logging: Using metadata objects instead of string concatenation

3. Updated Backend Files:

API Routes:

• app/api/generate-plan/route.ts - 12 console statements replaced
• app/api/generate-content/route.ts - 12 console statements replaced
• app/api/generate-lesson-audio/route.ts - 1 console statement replaced

Services:

• lib/openai.ts - 20+ console statements replaced across both functions
• app/api/backend/playground.ts - 3 console statements replaced

4. Logging Improvements:

• Structured data: Instead of console.log('Duration:', duration, 'ms'), now using log.info('Duration:', { duration_ms: duration })
• Appropriate levels: Using debug for verbose output, info for general flow, error for errors
• Metadata objects: Error details, timings, and other data properly structured
• Removed redundant output: Eliminated duplicate logging and consolidated related information

5. Benefits:

• Production-ready: Proper log levels and file output for production
• Searchable: Structured JSON logs in production
• Filterable: Different log levels can be controlled via environment
• Maintainable: Centralized logging configuration
• Performance: Better than string concatenation in console.log

All backend services now use Winston for consistent, professional logging while maintaining the same informational output during development.
