Discovering dnd kit: A Powerful Alternative for Drag-and-Drop Interfaces

As a developer, finding a reliable alternative to traditional drag-and-drop libraries can be a challenge. That’s where dnd kit comes in – a lightweight, performant, and extensible drag-and-drop toolkit for React. In this article, we’ll explore the features, advantages, and use cases of dnd kit.

What is dnd kit?

dnd kit is a relatively new player in the drag-and-drop landscape, but it has already gained significant attention from developers. As a direct alternative to traditional libraries, dnd kit offers a more modern and efficient approach to building drag-and-drop interfaces in React applications.

Key Features of dnd kit

• DndContext: The root component of dnd kit, which provides a context for all other components.
• Draggable: A hook that makes any React component draggable.
• Droppable: A hook that makes any React component a droppable target.
• Sensors: Input methods that initiate dragging, such as pointer, keyboard, touch, and mouse.
• Modifiers: Utility functions that modify the behavior of core components.

Building a Kanban Board with dnd kit

To demonstrate the power of dnd kit, we’ll build a basic Kanban board with three main components:

• KanbanCard: A draggable Kanban item that can be dropped into a droppable area.
• KanbanLane: A droppable area where Kanban cards can be dropped.
• KanbanBoard: The root component that holds everything together.

import { DndContext, Draggable, Droppable } from 'dnd-kit';

function KanbanCard() {
  return (
    <Draggable>
      <div>Kanban Card</div>
    </Draggable>
  );
}

function KanbanLane() {
  return (
    <Droppable>
      <div>Kanban Lane</div>
    </Droppable>
  );
}

function KanbanBoard() {
  return (
    <DndContext>
      <KanbanCard />
      <KanbanLane />
    </DndContext>
  );
}

Advantages of dnd kit

While traditional libraries are still popular, dnd kit offers several advantages, including:

• Lightweight and performant: dnd kit is designed to be fast and efficient, making it perfect for complex applications.
• Extensible: dnd kit provides a robust API for customization and extension.
• Modern architecture: dnd kit is built with modern React principles in mind, making it easy to integrate with other libraries and frameworks.

import { useSensor } from 'dnd-kit';

function KanbanCard() {
  const { setActivated, setDeactivated } = useSensor('pointer');

  return (
    <Draggable>
      <div>Kanban Card</div>
      {setActivated()}
      {setDeactivated()}
    </Draggable>
  );
}
