Description

Hello

We are using this library along with serverless framework for a long time but ever since we upgraded the serverless-offline framework to the latest version, we started noticing that the console is logging any colors. So I created a ticket in serverless-offline and upon further investigation, they said that it is due the code being run in the worker thread. Just want to point out there if that is something you can fix in this library. I noticed that you use color package and here is what one of the ticket says about the forked process.

Link to the serverless -offline ticket : https://github.com/dherault/serverless-offline/issues/1570

Link to colors ticket : https://github.com/Marak/colors.js/issues/253

Thanks in advance.

Research direction
First, review the referenced serverless offline ticket (https://github.com/dherault/serverless offline/issues/1570) and colors.js issue (https://github.com/Marak/colors.js/issues/253) for context. Then, examine how tracer applies colors in its logging, likely in the main logger file (e.g., lib/tracer.js). The problem may be that the 'colors' package checks isTTY, which returns false in worker threads. The fix could involve using a method to force color output or switching to a library like 'chalk' that supports worker threads. Verify if there is a configuration option in tracer to enable colors, and if not, propose adding one.
