Description

Context:

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:

1. Integrate Winston Logger:

   • Add Winston as a dependency to the project.
   • Set up Winston to handle logging within the Nest.js application.

2. Configure Logging Levels:

   • Define and configure different logging levels (info, debug, error, etc.) based on project requirements.

3. Output Formats:

   • Configure Winston to support various output formats such as JSON, text, etc.

4. Log File Rotation:

   • Implement log file rotation to manage log file sizes and prevent them from becoming too large.

Setup Instructions:

1. Installation:

   • Run yarn add winston to install the Winston logger.

2. Configuration:

   • Create a logger.service.ts file to handle Winston's configuration.
   • Configure transports (Console, File, etc.) based on project needs.

3. 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.

4. 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.

Dependencies:

• Node.js (20.10.0)
• Nest.js (10.3.0)
