@ajayos/nodelogger NPM

nodelogger

@ajayos/nodelogger is a Node.js module for logging messages with customizable severity levels and output formats.

Installation

To install @ajayos/nodelogger, run:

npm install @ajayos/nodelogger

Usage

First, import the module into your Node.js application:

const Logger = require("@ajayos/nodelogger");

Then, create an instance of the Logger class with the desired configuration options and start it:

const options = {
  timeZone: "Asia/Kolkata",
  hour: "numeric",
  minute: "numeric",
  hour12: true,
  filename: "logs/%DATE%.log",
  datePattern: "YYYY-MM/DD",
  zippedArchive: false,
  maxSize: "1g",
  level: "info",
};

const logger = new Logger(options);

Once the logger is started, you can log messages with the log method:

logger.error("This is an error message");
logger.warn("This is a warning message");
logger.info("This is an info message");
logger.debug("This is a debug message");
logger.fatal("This is a fatal message");

You can also log messages with the default severity level by omitting the second argument:

logger.log("This is a default message");

To log a horizontal line, use:

logger.line();

To clear screen:

logger.clear()
