How does tracer.warn work?

tracer.warn is a function provided by the tracer library that logs a warning message to the console or a file, depending on the configuration. When called, tracer.warn creates a new log event with the WARN level, and appends the provided message to the log event. The log event is then sent to the appenders defined in the tracer configuration. By default, tracer will log warning messages to the console using the console.warn method. However, the behavior of tracer can be customized by creating a configuration object and specifying different appenders and log levels. Overall, tracer.warn provides a convenient way to log warning messages to the console or a file in a Node.js application.

const tracer = require("tracer");

const logger = tracer.colorConsole();

logger.warn("This is a warning message");

In this example, we use tracer.warn to log a warning message to the console. We first import the tracer library using the require function and assign it to the variable tracer. We then call tracer.colorConsole() to get a console logger instance that will log messages with colors. We call logger.warn and pass in a string message as the argument. This creates a new log event with the WARN level and appends the message to the log event. The log event is then sent to the console appender, which logs the message to the console with a warning level. Note that in order to use tracer.warn, you need to have the tracer library installed and imported in your application, and you may also need to create a tracer configuration object to specify custom appenders and log levels.
