EU Infinite Scrolling Compliance SDK - A drop-in React pagination library for GDPR/DSA compliance with virtual scrolling for high-performance rendering.

🌍 Why PaginateFlow?

The EU's Digital Services Act (DSA) bans manipulative infinite scrolling on social platforms. PaginateFlow provides a compliant alternative with:

• ✅ GDPR/DSA Compliant - Explicit pagination replaces infinite scrolling
• ✅ Virtual Scrolling - Renders only visible items (10,000+ items without lag)
• ✅ Auto Load Detection - Triggers 500px before end of list
• ✅ Analytics Hooks - Track page loads, scroll depth, and user engagement
• ✅ Zero Runtime Dependencies - Only TanStack Virtual as peer dependency
• ✅ Small Bundle - ~23KB unzipped (6.88KB gzipped)

📦 Installation

npm install @vibecaas/paginate-flow @tanstack/react-virtual

or

yarn add @vibecaas/paginate-flow @tanstack/react-virtual

or

pnpm add @vibecaas/paginate-flow @tanstack/react-virtual

🚀 Quick Start

import { VirtualizedList } from '@vibecaas/paginate-flow';

function App() {
  const [items, setItems] = useState([]);
  const [hasMore, setHasMore] = useState(true);

  const fetchNextPage = async () => {
    const newItems = await fetch('/api/items?page=' + currentPage);
    setItems(prev => [...prev, ...newItems]);
    setHasMore(newItems.length > 0);
  };

  return (
    <VirtualizedList
      items={items}
      renderItem={(item) => <Card key={item.id} {...item} />}
      onLoadMore={fetchNextPage}
      hasMore={hasMore}
      estimatedItemHeight={150}
      height="100vh"
    />
  );
}

📚 Components

VirtualizedList

The main component for efficient list rendering with pagination.

<VirtualizedList<T>
  items={T[]}
  renderItem={(item: T, index: number) => ReactNode}
  getItemKey?: (item: T, index: number) => string | number
  estimatedItemHeight?: number  // Default: 80px
  height?: number | string  // Default: "100vh"
  onLoadMore?: () => void | Promise<void>
  hasMore?: boolean
  loadMoreThreshold?: number  // Default: 500px
  analytics?: AnalyticsHandlers
  loadingComponent?: ReactNode
  showComplianceBadge?: boolean  // Default: true
  footer?: ReactNode
/>

LoadMoreButton

A standalone button component for manual load more triggers.

<LoadMoreButton
  hasMore={boolean}
  isLoading?: boolean
  onLoadMore={() => void | Promise<void>}
  loadingLabel?: string
  idleLabel?: string
  disabled?: boolean
  className?: string
/>

ComplianceBadge

GDPR compliance badge component.

<ComplianceBadge
  position?: 'top-left' | 'top-right' | 'bottom-left' | 'bottom-right'
  label?: string
  className?: string
  showTooltip?: boolean
  tooltipText?: string
/>

🪝 Hooks

usePagination

Manage pagination state.

const { state, nextPage, prevPage, goToPage, reset } = usePagination({
  itemsPerPage: 20,
  initialPage: 1,
  totalItems: 100,
  fetchPage: async (page: number) => { ... }
});

// State: { currentPage, totalPages, itemsPerPage, totalItems, isLoading, hasMore }

useScrollAnalytics

Track scroll events for analytics.

const { scrollDepth, handleScroll, resetTracking, trackPageLoad, trackItemRender } = useScrollAnalytics({
  analytics: {
    onPageLoad: (page) => Analytics.track('page_loaded', { page }),
    onScrollDepth: (depth) => Analytics.track('scroll_depth', { depth }),
    onItemRender: (item, index) => Analytics.track('item_rendered', { index })
  },
  throttleMs: 100
});

📊 Analytics Integration

PaginateFlow provides hooks for tracking user engagement:

<VirtualizedList
  items={items}
  renderItem={renderItem}
  onLoadMore={fetchNextPage}
  hasMore={hasMore}
  analytics={{
    onPageLoad: (page) => {
      // Fire when a new page loads
      console.log('Page loaded:', page);
      Analytics.track('page_loaded', { page });
    },
    onItemRender: (item, index) => {
      // Fire when an item is rendered
      console.log('Item rendered:', index);
      Analytics.track('item_rendered', { index });
    },
    onScrollDepth: (depth) => {
      // Fire when scroll depth changes
      console.log('Scroll depth:', depth);
      Analytics.track('scroll_depth', {
        page: depth.page,
        percentage: depth.percentage,
        visibleItems: depth.visibleItems,
        totalItems: depth.totalItems,
      });
    },
  }}
/>

🎨 Styling

PaginateFlow is styled with Tailwind CSS classes. The components expose className props for customization:

<LoadMoreButton className="w-full max-w-md mx-auto" />
<ComplianceBadge className="top-4 right-4" />

🔧 TypeScript

Full TypeScript support with exported types:

import type {
  VirtualizedListProps,
  AnalyticsHandlers,
  ScrollDepth,
  PaginationState,
  UsePaginationOptions
} from '@vibecaas/paginate-flow';

📝 Example Usage

See the demo app for a complete implementation or visit the live demo at:

demo.paginateflow.dev

Mock Data Example

const generatePosts = (startId: number, count: number) => {
  return Array.from({ length: count }, (_, i) => ({
    id: startId + i,
    title: `Post #${startId + i}`,
    content: '...',
  }));
};

<VirtualizedList
  items={posts}
  renderItem={(post) => <PostCard key={post.id} {...post} />}
  onLoadMore={() => {
    const newPosts = generatePosts(posts.length, 20);
    setPosts(prev => [...prev, ...newPosts]);
  }}
  hasMore={posts.length < 200}
  analytics={analytics}
/>

🧪 Performance

• ✅ Renders 10,000+ items without lag
• ✅ Only renders visible items (virtual scrolling)
• ✅ Debounced scroll events (100ms default)
• ✅ Optimized re-rendering with React.memo

🛡️ GDPR/DSA Compliance

PaginateFlow helps you comply with:

• EU Digital Services Act (DSA) - Article 25 bans dark patterns like infinite scrolling
• GDPR Article 25 (Data Protection by Design) - Explicit user control over content consumption

The compliance badge signals to users that your app respects EU regulations.
