We aim to enhance the logging capabilities of our Nest.js application by integrating the Winston logger. Winston is a versatile logging library for Node.js, providing flexibility and extensibility.
Proposed Changes:
Integrate Winston Logger:
Add Winston as a dependency to the project.
Set up Winston to handle logging within the Nest.js application.
Configure Logging Levels:
Define and configure different logging levels (info, debug, error, etc.) based on project requirements.
Output Formats:
Configure Winston to support various output formats such as JSON, text, etc.
Log File Rotation:
Implement log file rotation to manage log file sizes and prevent them from becoming too large.
Setup Instructions:
Installation:
Run yarn add winston to install the Winston logger.
Configuration:
Create a logger.service.ts file to handle Winston's configuration.
Configure transports (Console, File, etc.) based on project needs.
Usage in Nest.js:
Import the Winston module and the logger service in Nest.js components where logging is required.
Use the logger service to log messages at various levels.
Example Usage:
Provide examples of how to use Winston logger in controllers, services, and middleware.
Additional Notes:
Ensure that the logging configuration is customizable, allowing developers to adjust settings according to specific project requirements.
Consider creating a sample logging middleware or interceptor to demonstrate how to log incoming requests, outgoing responses, and errors.
Test the logging setup thoroughly to ensure it meets project standards and effectively captures relevant information.
Acceptance Criteria:
Winston logger is successfully integrated into the Nest.js application.
Logging levels and formats are configurable.
Log rotation is implemented and tested.
Setup instructions are provided, and examples demonstrate proper usage.
