+
+[![npm version][npm-version-src]][npm-version-href]
+[![npm downloads][npm-downloads-src]][npm-downloads-href]
+[![Unit Test][unit-test-src]][unit-test-href]
+
+A lightweight JavaScript debugging utility, forked from [debug](https://www.npmjs.com/package/debug), featuring TypeScript and ESM support.
+
+> [!NOTE]
+> obug v1 retains most of the compatibility with [debug](https://github.com/debug-js/debug), but drops support for older browsers and Node.js, making it a drop-in replacement.
+>
+> obug 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
+  - 7.7 kB package size
+  - 1.4 KB minified + gzipped for browsers
+- 📦 Zero dependencies
+- 📝 Full TypeScript support
+- 🚀 Native ESM compatibility
+- 🌐 Optimized for modern runtimes
+  - ES2015+ browsers
+  - Modern Node.js versions
+- 🎨 Customizable formatting
+
+## Installation
+
+```bash
+npm install obug
+```
+
+## Usage
+
+```ts
+import { createDebug, disable, enable, enabled, namespaces } from 'obug'
+
+// Get the currently enabled namespaces
+console.log(namespaces())
+
+const debug = createDebug('my-namespace', {
+  // All options are optional
+
+  useColors: true, // false, true, undefined for auto-detect
+  color: 2, // custom color
+  // custom formatArgs
+  formatArgs(args) {},
+  formatters: {},
+  // Node.js only
+  inspectOpts: {},
+
+  // custom log
+  log: console.log,
+})
+
+debug('This is a debug message')
+console.log(
+  debug.namespace, // 'my-namespace'
+  debug.enabled, // Check if enabled
+  debug.useColors, // true
+  debug.color, // 2
+  debug.formatArgs, // custom formatArgs
+  debug.formatters, // {}
+  debug.inspectOpts, // {}
+  debug.log, // implemented log function
+)
+
+// Create a sub-namespace, and it will inherit options from the parent debugger
+const sub = debug.extend('sub-namespace')
+sub('This is a sub-namespace debug message')
+console.log(sub.namespace) // 'my-namespace:sub-namespace'
+```
