7-7: Good replacement of console.log with structured logging.The use of
logger.infoinstead ofconsole.logis a significant improvement. It provides better structure and consistency in logging, allowing for easier log management and potential integration with log analysis tools.A minor suggestion: Consider including the server's base URL in the log message for completeness.
You might want to include the full URL in the log message. Here's a suggested change:
- logger.info(`Listening to port ${port}`) + logger.info(`Server is running at http://localhost:${port}`)This provides more context in the logs, which can be helpful for debugging or when running on different environments.

12-21: LGTM: Well-structured logger configuration with a minor suggestion.The logger configuration is well done, considering different environments and using both file and console transports.
Consider adding a timestamp to the log format for better traceability:
winston.format.printf( ({ level, message, timestamp }) => `${timestamp} ${level}: ${message}` ),You can add the timestamp by including
winston.format.timestamp()in theformat.combine()array.package.json (1)
35-36: LGTM! Consider adding a script for log rotation.The addition of
winstonandwinston-daily-rotate-filedependencies is appropriate for setting up a winston logger with daily log rotation. The versions are up-to-date and the use of caret ranges allows for minor version updates, which is a good practice.Consider adding a npm script in the
"scripts"section to manage log rotation or cleanup, such as:"scripts": { ... "rotate-logs": "node scripts/rotateLogs.js" }This would make it easier to manage log files, especially in a production environment.

3-3: LGTM: Proper import of the new logger.The import of the
loggerfrom the./config/loggerfile aligns well with the PR objective of setting up the winston logger. This change centralizes the logging configuration and allows for consistent logging across the application.src/config/logger.ts (3)
1-2: LGTM: Imports are correct and necessary.The imports for Winston and its daily rotate file transport are appropriate for setting up the logger.
12-12: LGTM: Logger export is correct.The logger is correctly exported, allowing it to be imported and used in other parts of the application.
1-22: Great implementation of Winston logger with room for minor enhancements.Overall, this is a solid implementation of a logging system using Winston. It considers different environments, uses both file and console logging, and sets up a daily rotate file system for log management.
To further improve this implementation, consider:
- Making file transport configuration more flexible through environment variables.
- Adding error handling for the file transport.
- Including a timestamp in the log format.
These enhancements will make the logging system more robust and adaptable to different deployment scenarios.

7-13: LGTM: Logging variables added, with minor improvement suggestions.The addition of Winston logging configuration variables is a good step towards improving the application's logging capabilities. However, consider the following suggestions to enhance usability:
Provide example values or brief descriptions for each variable to guide users. For instance:
LOG_LEVEL=info LOG_FILE_PATH=logs/%DATE%.log LOG_DATE_PATTERN=YYYY-MM-DD LOG_ZIPPED_ARCHIVE=true LOG_MAX_SIZE=20m LOG_MAX_FILES=14dExpand the comment to briefly explain the purpose of these variables:
# Winston logger configuration (https://github.com/winstonjs/winston#readme) # These variables control log levels, file rotation, and retention policiesThese changes would make it easier for developers to understand and configure the logging system correctly.
