MagicLogger — Colorful JavaScript / TypeScript Logger

What's MagicLogger?

A powerful, zero-config logging library for Node.js and browsers with rich styling, transport options, and a universal schema for logging styles compatible with OpenTelemetry.

Simplify your logging with a single library that works everywhere.

Key Features

• 🎨 Rich Styling — Colors, bold, italic, underline in terminal and browser console
• 📊 Visual Elements — Progress bars and tables directly in your console
• 📝 Multiple Transports — Console, file, browser storage, and remote HTTP endpoints
• 🔌 Drop-in Compatibility — Replace console, Winston, Bunyan, and Pino seamlessly
• 🧠 Structured Logging — Support for both text and JSON formats
• ⚡ Zero Config & Zero Dependencies — Works out of the box with sensible defaults
• 🌐 Environment Aware — Automatically adapts to Node.js or browser
• 🧵 Multiple Module Formats — ESM, CommonJS, and TypeScript declarations

Quick Start

import { Logger } from 'magiclogger';

// Create a new logger with default settings
const logger = new Logger();

// Log with different levels
logger.info('Application starting up...');
logger.warn('Connection pool nearing capacity');
logger.error('Database connection failed');
logger.debug('User authentication details');
logger.success('Email sent successfully');

// Add visual elements
logger.header('SYSTEM STATUS');
logger.progressBar(75);  // 75% progress bar

// Structured logging
logger.info('User logged in', { userId: 123, ip: '192.168.1.1' });

Powerful Transports

MagicLogger sends your logs wherever you need them:

const logger = new Logger({
  // Log to console with colors
  console: { 
    enabled: true, 
    useColors: true 
  },
  
  // Save logs to files (Node.js)
  file: { 
    enabled: true, 
    directory: './logs' 
  },
  
  // Store logs in browser localStorage
  browserStorage: { 
    enabled: true, 
    maxEntries: 1000 
  },
  
  // Send critical logs to your server
  remote: {
    enabled: true,
    endpoint: 'https://logs.example.com/api/logs',
    levels: ['error', 'warn']
  }
});

Replace Existing Loggers

Enhance your existing logging code without refactoring:

// Enhance the standard console
import { enhanceConsole } from 'magiclogger';
enhanceConsole();

// Now standard console has new powers
console.header('APPLICATION STATUS');
console.success('All systems operational');

// Create Winston/Bunyan/Pino compatible loggers
import { createWinstonCompatible } from 'magiclogger';
const logger = createWinstonCompatible({ verbose: true });

Coming Soon!

MagicLogger is currently in development and will be available soon. Stay tuned for its release!
