Basic Incantations: Getting Started with React-Dragula

Let’s dive into some basic usage examples to get you started with React-Dragula.

The Simple Drag-and-Drop Spell

Here’s a straightforward example to create a drag-and-drop container:

import React, { useEffect, useRef } from 'react';
import dragula from 'react-dragula';

const DragDropContainer: React.FC = () => {
  const containerRef = useRef<HTMLDivElement>(null);

  useEffect(() => {
    if (containerRef.current) {
      dragula([containerRef.current]);
    }
  }, []);

  return (
    <div ref={containerRef}>
      <div>Drag me</div>
      <div>Drag me too</div>
      <div>And me!</div>
    </div>
  );
};

export default DragDropContainer;

In this example, we create a container with draggable elements. The useEffect hook initializes Dragula on the container when the component mounts. Now, users can freely drag and reorder the elements within the container.

Enchanting Multiple Containers

React-Dragula allows you to create multiple drag-and-drop zones. Here’s how you can set up two containers that interact with each other:

import React, { useEffect, useRef } from 'react';
import dragula from 'react-dragula';

const MultipleContainers: React.FC = () => {
  const leftContainerRef = useRef<HTMLDivElement>(null);
  const rightContainerRef = useRef<HTMLDivElement>(null);

  useEffect(() => {
    if (leftContainerRef.current && rightContainerRef.current) {
      dragula([leftContainerRef.current, rightContainerRef.current]);
    }
  }, []);

  return (
    <div>
      <div ref={leftContainerRef}>
        <div>Item 1</div>
        <div>Item 2</div>
      </div>
      <div ref={rightContainerRef}>
        <div>Item 3</div>
        <div>Item 4</div>
      </div>
    </div>
  );
};

export default MultipleContainers;

This setup allows users to drag items between the left and right containers, creating a dynamic and interactive interface.

Advanced Sorcery: Mastering React-Dragula

Now that we’ve covered the basics, let’s explore some more advanced techniques to harness the full power of React-Dragula.

Customizing the Drag Behavior

React-Dragula offers various options to customize the drag-and-drop behavior. Here’s an example that demonstrates how to control which elements can be moved:

import React, { useEffect, useRef } from 'react';
import dragula from 'react-dragula';

const CustomDragBehavior: React.FC = () => {
  const containerRef = useRef<HTMLDivElement>(null);

  useEffect(() => {
    if (containerRef.current) {
      dragula([containerRef.current], {
        moves: (el, container, handle) => {
          return handle.classList.contains('handle');
        }
      });
    }
  }, []);

  return (
    <div ref={containerRef}>
      <div><span className="handle">☰</span> Drag me using the handle</div>
      <div><span className="handle">☰</span> Me too!</div>
      <div>I can't be dragged</div>
    </div>
  );
};

export default CustomDragBehavior;

In this example, only elements with a child that has the ‘handle’ class can be dragged, providing more control over the user interaction.

Conjuring Copy Instead of Move

Sometimes, you might want to copy elements instead of moving them. React-Dragula makes this easy:

import React, { useEffect, useRef } from 'react';
import dragula from 'react-dragula';

const CopyDragDrop: React.FC = () => {
  const sourceRef = useRef<HTMLDivElement>(null);
  const targetRef = useRef<HTMLDivElement>(null);

  useEffect(() => {
    if (sourceRef.current && targetRef.current) {
      dragula([sourceRef.current, targetRef.current], {
        copy: (el, source) => source === sourceRef.current,
        accepts: (el, target) => target === targetRef.current
      });
    }
  }, []);

  return (
    <div>
      <div ref={sourceRef}>
        <div>Copy me</div>
        <div>Copy me too</div>
      </div>
      <div ref={targetRef}>
        <div>Drop zone</div>
      </div>
    </div>
  );
};

export default CopyDragDrop;

This setup allows elements to be copied from the source container to the target container, rather than moved.

Harnessing the Power of Events

React-Dragula emits various events during the drag-and-drop process, allowing you to respond to user actions:

import React, { useEffect, useRef } from 'react';
import dragula from 'react-dragula';

const EventfulDragDrop: React.FC = () => {
  const containerRef = useRef<HTMLDivElement>(null);

  useEffect(() => {
    if (containerRef.current) {
      const drake = dragula([containerRef.current]);

      drake.on('drag', (el) => {
        console.log('Started dragging:', el);
      });

      drake.on('drop', (el, target, source, sibling) => {
        console.log('Dropped element:', el);
        console.log('Drop target:', target);
      });

      return () => {
        drake.destroy();
      };
    }
  }, []);

  return (
    <div ref={containerRef}>
      <div>Event-driven item 1</div>
      <div>Event-driven item 2</div>
    </div>
  );
};

export default EventfulDragDrop;

This example logs information about drag start and drop events, allowing you to perform custom actions or update your application state in response to user interactions.
