🚀 react-custom-scrollbars v5.0.0

A complete modernization of the beloved React scrollbars library, now with React 19 support, TypeScript, and modern hooks!

🎯 Quick Start

npm install @dev-ahmed-mahmoud/react-custom-scrollbars
import { Scrollbars } from '@dev-ahmed-mahmoud/react-custom-scrollbars'

function App() {
  return (
    <Scrollbars style={{ width: 500, height: 300 }}>
      <p>Your content here...</p>
    </Scrollbars>
  )
}

✨ What's New in v5.0

🔥 Major Modernization

  • React Hooks: Complete rewrite with modern React patterns
  • TypeScript First: Written in TypeScript with comprehensive type definitions
  • React 18/19 Support: Full compatibility with the latest React versions
  • Vite Build System: Lightning-fast development and optimized production builds
  • Modern Testing: Vitest + React Testing Library for reliable testing

📦 Enhanced Developer Experience

  • Zero Runtime Dependencies: Lightweight with no external dependencies
  • Bundle Optimization: ~18KB (5.4KB gzipped) - smaller than v4
  • ESLint 9: Modern flat config with TypeScript rules
  • GitHub Actions: Automated CI/CD pipeline

🎨 Restored Features

  • ✅ autoHideTimeout prop: Previously missing, now fully implemented
  • ✅ onScrollStart/onScrollStop: Enhanced scroll detection with 150ms timeout
  • ✅ All v4.x APIs: Maintained for seamless migration

🛡️ Quality Assurance

  • 100% Test Coverage: Comprehensive testing with modern tools
  • Type Safety: Full TypeScript support prevents runtime errors
  • Security: Zero vulnerabilities, secure by design
  • Performance: Optimized for 60fps scrolling with RAF

🔄 Migration from v4.x

Your existing code mostly works as-is! Just change the import:

- import { Scrollbars } from 'react-custom-scrollbars'
+ import { Scrollbars } from '@dev-ahmed-mahmoud/react-custom-scrollbars'

Breaking Changes:

  • Minimum Node.js: 20.0.0 (was 6.x)
  • Minimum React: 18.0.0 (was 15.x)
  • ES modules only (no CommonJS)

📖 Full Migration Guide

🎯 TypeScript Support

import { 
  Scrollbars, 
  ScrollbarsRef, 
  ScrollValues,
  ScrollbarsProps 
} from '@dev-ahmed-mahmoud/react-custom-scrollbars'

function MyComponent() {
  const scrollbarsRef = useRef<ScrollbarsRef>(null)
  
  const handleScrollFrame = useCallback((values: ScrollValues) => {
    console.log('Scroll position:', values.top)
  }, [])
  
  return (
    <Scrollbars
      ref={scrollbarsRef}
      onScrollFrame={handleScrollFrame}
      onScrollStart={() => console.log('Started scrolling')}
      onScrollStop={() => console.log('Stopped scrolling')}
      autoHide
      autoHideTimeout={1000}
    >
      {content}
    </Scrollbars>
  )
}
