Why I Built dd-tinylog: A Lightweight Logging Library Made for Speed and Simplicity

The Core Problem: Logging Has Become Too Heavy

In many Node.js projects, logging libraries try to handle too much at once:

complex configuration files
confusing APIs
nested options that make setup slower than writing your own wrapper
blocking writes that slow down the event loop
inconsistent performance between development mode and production

I wanted to create a logger that didn’t feel like a burden. You should be able to add it to a project quickly and rely on it without thinking too much.

The Philosophy Behind dd-tinylog

1 . It is Lightweight
Minimal overhead. Fast defaults. Async transports avoid blocking.

2 . It is Flexible
Use text or JSON, choose timestamps, customize prefixes, and change log levels on the fly.

3 . Making Simple Structures
Child loggers offer clear separation between modules, requests, or components.

Real Usage Example

Installation

npm install dd-tinylog

Simple Use of logger

import { Logger } from 'dd-tinylog';

const logger = new Logger({
  level: 'info',
  async: true,
  colorize: true,
  transports: [
    { type: 'console' },
    { type: 'file', options: { path: './logs/app.log' } },
  ],
  prefix: '[My-App]',
  timestamp: true,
});

logger.info('Server started');
logger.warn('Low disk space');
logger.error('Database error', { code: 500 });

Child Loggers

const requestLogger = logger.createChild({
  prefix: '[Request-123]',
  context: { requestId: 'req-123' },
});

requestLogger.info('Processing request');
