[konard]

🎯 Summary

This PR implements the complete solution for issue #2 by successfully moving and adapting the infinite depth tree functionality from the InfiniteDepthTreeWebUIPrototype vanilla JavaScript implementation to a modern React package.

🔗 Issue Reference

Fixes #2

✨ Key Features Implemented

• 🌳 Infinite Depth Tree Rendering: Recursive React components support unlimited nesting levels
• ⌨️ Keyboard Navigation: Arrow keys and mouse wheel navigation through tree items
• 🔍 Real-time Search: Dynamic filtering with "/" hotkey to toggle search input
• 🎯 Smart Selection: Auto-scroll and highlight selected items with smooth animations
• 🎨 Customizable Architecture: Flexible prop system to replace default HTML elements
• 📱 Responsive Design: Mobile-friendly layout with proper styling
• 🔧 TypeScript Support: Complete type definitions and interfaces
• 🪝 Navigation Hook: Reusable useTreeNavigation hook for advanced usage

🛠️ Technical Implementation

Core Components

• DeepTree: Main component with navigation and search capabilities
• TreeNode: Recursive component for rendering individual tree nodes
• useTreeNavigation: Custom hook for keyboard/mouse navigation logic

Navigation Controls

• ↑/↓ Arrow Keys: Navigate up/down through items
• Mouse Wheel: Scroll-based navigation
• / key: Toggle search input
• ESC: Close search input
• Click: Select items directly

Styling & Theming

• Dark theme inspired by original prototype (#1F1F1F background, #EA7500 accent)
• Smooth transitions and animations
• Responsive breakpoints for mobile
• Optional CSS file (styles.css) for quick styling

📦 Package Updates

• Version: Bumped to 0.1.0 to reflect major feature additions
• Description: Updated to reflect new navigation and search capabilities
• Dependencies: Maintained existing peer dependencies (React 16+)
• Build: TypeScript compilation working with proper type exports

📖 Documentation & Examples

Enhanced README

• Complete API reference with all props documented
• Usage examples from basic to advanced scenarios
• Keyboard shortcuts reference
• Styling guide with customization options

Interactive Examples

• Basic Tree: Static tree rendering
• Navigation Demo: Keyboard/mouse navigation with visual feedback
• Search Demo: Real-time filtering functionality
• Custom Components: Demonstrating component customization

🧪 Usage Examples

Basic Usage

import DeepTree, { DataNode } from 'react-deep-tree';

const data: DataNode[] = [
  {
    content: 'Root Item',
    children: [
      { content: 'Child 1' },
      { content: 'Child 2', children: [/* nested items */] }
    ]
  }
];

export default function App() {
  return <DeepTree data={data} />;
}

With Navigation & Search

<DeepTree
  data={data}
  enableNavigation={true}
  enableSearch={true}
  onNodeSelect={(node, index) => console.log('Selected:', node.content)}
/>

Custom Components

<DeepTree
  data={data}
  ListItem={MyCustomListItem}
  ContentFrame="span"
  TreeFrame="section"
  enableNavigation={true}
/>

✅ Test Plan

• Basic tree rendering with nested data structures
• Keyboard navigation (arrow keys, wheel scroll)
• Search functionality with real-time filtering
• TypeScript compilation and type checking
• Component customization with different HTML elements
• Mobile responsive design
• Smooth animations and transitions
• Auto-scroll to selected items
• Example components and documentation

🔄 Compatibility

• React: 16.13.1+ (peer dependency)
• TypeScript: 3.9.7+ for development
• Browser: Modern browsers with ES2015+ support
• Mobile: Responsive design with touch-friendly interactions

📋 Migration Notes

This implementation maintains backward compatibility with the existing simple tree structure while adding powerful new features:

• Existing DataNode interface unchanged (children property now optional)
• Default behavior remains the same for basic usage
• New features are opt-in via props
• No breaking changes to existing API

This PR transforms the react-deep-tree package from a simple tree renderer into a powerful, interactive navigation component that faithfully adapts the innovative UI concepts from the InfiniteDepthTreeWebUIPrototype while leveraging React's component architecture and modern web development practices.
