React Brickwall Drag & Drop  

React Brickwall Drag & Drop is a fancy way to move items across multiple data sources via React-driven UI.

Installing

npm install react-brickwall-dnd

Usage

All dropzones should be wrapped inside a <Brickwall /> component. Any HTML element inside <Brickwall /> that has an id prop starting with bw-dz will be considered a dropzone. Dropzones cannot be nested. All direct children of a dropzone are draggable items.

React Brickwall provides a handy way of controlling data source changes via useDataSourceController() hook. It handles storing each dropzone's items in state and automatically handles all item replacements. This hook returns two values:

• lists is a dictionary where key is dropzone id and value is an array of your data objects;
• handleItemDrop() is a function that is provided to <Brickwall /> component's onItemDrop prop and automatically updates data object lists for each dropzone.

Each time items composition changes inside <Brickwall /> context, lists returned from the above hook will be updated with latest changes.

Alternatively you can manually store dropzone data sources wherever you like and pass your custom "on drop" handler to onItemDrop prop.

Example:

import Brickwall, { useDataSourceController } from "react-brickwall-dnd";

interface ShufflerComponentProps {
  listA: Item[];
  listB: Item[];
  listC: Item[];
}

const ShufflerComponent: React.FC<ShufflerComponentProps> = ({ listA, listB, listC }) => {
  const { lists, handleItemDrop } = useDataSourceController({
    "bw-dz-list-a": listA,
    "bw-dz-list-b": listB,
    "bw-dz-list-c": listC,
  });

  React.useEffect(() => {
    // do your thing with updated data
  }, [lists]);

  return (
    <Brickwall animationSpeed={200} gridGap={20} onItemDrop={handleItemDrop}>
      <div id="bw-dz-list-a">
        {lists["bw-dz-list-a"].map((item) => (
          <div key={item.id}>{item.text}</div>
        ))}
      </div>
      // it doesn't matter how deep you put your dropzones relative to <Brickwall />
      <section>
        <div id="bw-dz-list-b">
          {lists["bw-dz-list-b"].map((item) => (
            <div key={item.id}>{item.text}</div>
          ))}
        </div>

        <div>
          <div id="bw-dz-list-c">
            {lists["bw-dz-list-c"].map((item) => (
              <div key={item.id}>{item.text}</div>
            ))}
          </div>
        </div>
      </section>
    </Brickwall>
  );
};
