obug

A lightweight JavaScript debugging utility, forked from debug, featuring TypeScript and ESM support.

[!NOTE] obug v1 retains most of the compatibility with debug, but drops support for older browsers and Node.js, making it a drop-in replacement.

The upcoming v2 refactors some API imports and usage for better support of ESM and TypeScript, easier customization, and an even smaller package size.

Key Differences from debug

• ✨ Minimal footprint
• 📦 Zero dependencies
• 📝 Full TypeScript support
• 🚀 Native ESM compatibility
• 🌐 Optimized for modern runtimes
  • ES2015+ browsers
  • Node.js 20.19 and above

Installation

Usage
