Creating a logger in Node.js from scratch

Logging is a crucial aspect of application development, and while console logging is powerful, developers often need a more comprehensive logging solution that includes logging to files and other outputs. The text discusses creating a unified logging system that automatically logs messages to the console, files, or potentially other destinations using a custom-built logger or established libraries like Winston. It explains the benefits of building a logger from scratch to gain insights into how logging libraries function and the potential to add unique features. The text outlines a system using a configurable logger with different transports, such as console and file transports, which allow for message formatting, level-based filtering, and customization through templates and tag functions. This approach enhances log management by offering flexibility in how and where logs are recorded, making it easier to track application behavior and debug issues efficiently.
