Replace all console.* calls with an appropriate structured logging framework using proper log levels. This ensures consistent logging patterns, better log management, and appropriate handling of different severity levels. Key guidelines: - Use logger.debug() for development/troubleshooting information - Use logger.info() for general operational information - Use logger.warn() for concerning but non-critical issues - Use logger.error() for critical issues and errors - Pass objects directly to logger instead of string interpolation Example: ```typescript // Don't do this: console.log("Processing batch:", JSON.stringify(batch)); console.warn("Redis client not available"); console.error("Failed to process:", error); // Do this instead: logger.info("Processing batch", { batch }); logger.warn("Redis client not available"); logger.error("Failed to process", { error }); ``` This approach provides better log management, filtering capabilities, and consistent logging patterns across the codebase.
