React

Overview

The React adapter provides hooks and components that seamlessly integrate drag and drop into your React applications with full TypeScript support.

Installation

Install the React package and its dependencies:

npm install @dnd-kit/react @dnd-kit/dom @dnd-kit/abstract

Requirements: React 18.0.0 or higher

Getting Started

Add DragDropProvider

Wrap your application with the DragDropProvider:

import {DragDropProvider} from '@dnd-kit/react';

function App() {
  return (
    <DragDropProvider>
      {/* Your app content */}
    </DragDropProvider>
  );
}

Create draggable components

Use the useDraggable hook to make elements draggable:

import {useDraggable} from '@dnd-kit/react';

function DraggableCard({id, title}) {
  const {ref, isDragging} = useDraggable({
    id,
    data: {title},
  });

  return (
    <div ref={ref} style={{opacity: isDragging ? 0.5 : 1}}>
      {title}
    </div>
  );
}

Create droppable zones

Use the useDroppable hook to create drop targets:

import {useDroppable} from '@dnd-kit/react';

function DroppableZone({id, children}) {
  const {ref, isDropTarget} = useDroppable({id});

  return (
    <div
      ref={ref}
      style={{
        backgroundColor: isDropTarget ? 'lightblue' : 'transparent',
      }}
    >
      {children}
    </div>
  );
}

Handle drag events

Listen to events via the provider props:

function App() {
  const handleDragEnd = (event) => {
    const {source, target} = event.operation;
    console.log('Dropped', source.id, 'on', target?.id);
  };

  return (
    <DragDropProvider onDragEnd={handleDragEnd}>
      {/* Your components */}
    </DragDropProvider>
  );
}

Complete Example

Here’s a full drag and drop implementation:

import {useState} from 'react';
import {DragDropProvider, useDraggable, useDroppable} from '@dnd-kit/react';

function DraggableItem({id, label}) {
  const {ref, isDragging, isDragSource} = useDraggable({
    id,
    data: {label},
  });

  return (
    <div
      ref={ref}
      style={{
        padding: '16px',
        margin: '8px',
        backgroundColor: isDragging ? '#e3f2fd' : '#f5f5f5',
        border: isDragSource ? '2px solid #2196f3' : '1px solid #ddd',
        borderRadius: '4px',
        cursor: 'grab',
      }}
    >
      {label}
    </div>
  );
}

function DroppableZone({id, title, items}) {
  const {ref, isDropTarget} = useDroppable({id});

  return (
    <div
      ref={ref}
      style={{
        minHeight: '200px',
        padding: '16px',
        margin: '8px',
        backgroundColor: isDropTarget ? '#e8f5e9' : '#fafafa',
        border: '2px dashed #ccc',
        borderRadius: '8px',
      }}
    >
      <h3>{title}</h3>
      {items.map((item) => (
        <DraggableItem key={item.id} id={item.id} label={item.label} />
      ))}
    </div>
  );
}

function App() {
  const [zones, setZones] = useState({
    'zone-1': [
      {id: 'item-1', label: 'Item 1'},
      {id: 'item-2', label: 'Item 2'},
    ],
    'zone-2': [
      {id: 'item-3', label: 'Item 3'},
    ],
  });

  const handleDragEnd = (event) => {
    const {source, target} = event.operation;
    
    if (!target) return;

    setZones((prev) => {
      const newZones = {...prev};
      
      // Remove from source zone
      Object.keys(newZones).forEach((zoneId) => {
        newZones[zoneId] = newZones[zoneId].filter(
          (item) => item.id !== source.id
        );
      });
      
      // Add to target zone
      const item = source.data;
      newZones[target.id] = [...newZones[target.id], item];
      
      return newZones;
    });
  };

  return (
    <DragDropProvider onDragEnd={handleDragEnd}>
      <div style={{display: 'flex', gap: '16px', padding: '24px'}}>
        <DroppableZone id="zone-1" title="Zone 1" items={zones['zone-1']} />
        <DroppableZone id="zone-2" title="Zone 2" items={zones['zone-2']} />
      </div>
    </DragDropProvider>
  );
}

Sortable Lists

Create sortable lists with the useSortable hook:

import {DragDropProvider} from '@dnd-kit/react';
import {useSortable} from '@dnd-kit/react/sortable';
import {useState} from 'react';

function SortableItem({id, index, label}) {
  const {ref, isDragging, isDragSource} = useSortable({
    id,
    index,
    group: 'list',
    data: {label},
  });

  return (
    <div
      ref={ref}
      style={{
        padding: '12px',
        margin: '4px 0',
        backgroundColor: isDragging ? '#e3f2fd' : 'white',
        border: isDragSource ? '2px solid #2196f3' : '1px solid #ddd',
        borderRadius: '4px',
        cursor: 'grab',
      }}
    >
      {label}
    </div>
  );
}

function SortableList() {
  const [items, setItems] = useState([
    {id: '1', label: 'Item 1'},
    {id: '2', label: 'Item 2'},
    {id: '3', label: 'Item 3'},
    {id: '4', label: 'Item 4'},
  ]);

  const handleDragEnd = (event) => {
    const {source, target} = event.operation;
    
    if (!target || source.index === target.index) return;

    setItems((prev) => {
      const newItems = [...prev];
      const [removed] = newItems.splice(source.index, 1);
      newItems.splice(target.index, 0, removed);
      return newItems;
    });
  };

  return (
    <DragDropProvider onDragEnd={handleDragEnd}>
      <div style={{maxWidth: '400px', padding: '24px'}}>
        {items.map((item, index) => (
          <SortableItem
            key={item.id}
            id={item.id}
            index={index}
            label={item.label}
          />
        ))}
      </div>
    </DragDropProvider>
  );
}

  ref: (element: Element | null) => void;
  handleRef: (element: Element | null) => void;
}

interface UseDraggableInput<T extends Data = Data> {
  id: string;
  element?: RefOrValue<Element>;
  handle?: RefOrValue<Element>;
  data?: T;
  disabled?: boolean;
  modifiers?: Modifier[];
  sensors?: Sensor[];
  plugins?: Plugin[];
  alignment?: Alignment;
}

The useDroppable hook signature from /home/daytona/workspace/source/packages/react/src/core/droppable/useDroppable.ts:22:

function useDroppable<T extends Data = Data>(
  input: UseDroppableInput<T>
): {
  droppable: Droppable<T>;
  isDropTarget: boolean;
  ref: (element: Element | null) => void;
}

Advanced Features

Drag Handles

Use separate elements for dragging:

function DraggableCard({id, title}) {
  const {ref, handleRef, isDragging} = useDraggable({id});

  return (
    <div ref={ref} style={{opacity: isDragging ? 0.5 : 1}}>
      <div ref={handleRef} style={{cursor: 'grab', padding: '8px'}}>
        ☰
      </div>
      <div>{title}</div>
    </div>
  );
}

Modifiers

Constrain drag behavior:

import {restrictToVerticalAxis} from '@dnd-kit/abstract/modifiers';

function App() {
  return (
    <DragDropProvider modifiers={[restrictToVerticalAxis]}>
      {/* Content */}
    </DragDropProvider>
  );
}

Sensors

Customize activation:

import {PointerSensor} from '@dnd-kit/dom';

function App() {
  const sensors = [
    new PointerSensor({
      activationConstraint: {
        delay: 250,
        tolerance: 5,
      },
    }),
  ];

  return (
    <DragDropProvider sensors={sensors}>
      {/* Content */}
    </DragDropProvider>
  );
}

Type Safety

Define custom data types:

interface TaskData {
  id: string;
  title: string;
  priority: 'low' | 'medium' | 'high';
}

function TaskCard({task}: {task: TaskData}) {
  const {ref, isDragging} = useDraggable<TaskData>({
    id: task.id,
    data: task,
  });

  return (
    <div ref={ref}>
      <h3>{task.title}</h3>
      <span>Priority: {task.priority}</span>
    </div>
  );
}

Best Practices

Stable IDs: Use consistent, unique IDs for draggables and droppables
Memoization: Memoize expensive computations in event handlers
Ref forwarding: When wrapping components, forward refs properly
State updates: Batch state updates in drag event handlers
Performance: Use React’s memo/useMemo for large lists
