ZeptoLogger

Because Micro-, Mini-, Pico-, Nano- and Femto- was already used.

ZeptoLogger is a simple and very small logging utility for Node.js applications. It provides functionality to log messages with different log levels and output formats.

Installation

You can install ZeptoLogger via npm:

npm install @stefanobalocco/zeptologger

Usage

import { ZeptoLogger, LogLevel, OutputType } from '@stefanobalocco/zeptologger';

// Get the singleton logger instance
const logger = ZeptoLogger.instance;

// Set minimum log level
logger.minLevel = LogLevel.INFO;

// Change output type
logger.outputType = OutputType.JSON;

// Change destination
logger.destination = process.stdout;

// Log a message
logger.log( LogLevel.INFO, 'This is an information message' );

Create a custom logger:

const logger = new ZeptoLogger( LogLevel.DEBUG, OutputType.JSON );

Create a child logger:

const child = logger.createChild( 'api' );
