Issue: error using `require` to import from react-dnd and react-dnd-html5-backend

Report

Current behavior

This library outputs a main dist/index.js file that attempts to use require to import from the react-dnd-html5-backend and react-dnd packages. However, these packages use ES modules, and this results in an error:

Error [ERR_REQUIRE_ESM]: require() of ES Module /Users/me/Code/my-project/node_modules/react-dnd-html5-backend/dist/index.js from /Users/me/Code/my-project/node_modules/@minoru/react-dnd-treeview/dist/index.js not supported.
Instead change the require of /Users/me/Code/my-project/node_modules/react-dnd-html5-backend/dist/index.js in /Users/me/Code/my-project/node_modules/@minoru/react-dnd-treeview/dist/index.js to a dynamic import() which is available in all CommonJS modules.

I’m currently using Next.JS, and I understand that next should be preferring ES modules where possible. However, in this case it is choosing the CJS export of react-dnd-treeview, which isn’t working with the latest versions of react-dnd and react-dnd-html5-backend.

Usage:

import { Tree } from "@minoru/react-dnd-treeview";

<Tree
  tree={treeData}
  rootId={0}
  render={(node, { depth, isOpen, onToggle }) => (
    <Task
      node={node}
      depth={depth}
      isOpen={isOpen}
      onToggle={onToggle}
      addTask={addTask}
    />
  )}
  dragPreviewRender={(monitorProps) => (
    <CustomDragPreview monitorProps={monitorProps} />
  )}
  onDrop={handleDrop}
  classes={{
    root: styles.treeRoot,
    draggingSource: styles.draggingSource,
    placeholder: styles.placeholderContainer,
  }}
  sort={false} //(node) => node.data?.ordinal || 0}
  insertDroppableFirst={false}
  canDrop={(_tree, { dragSource, dropTargetId, dropTarget }) => {
    if (dragSource?.parent === dropTargetId) {
      return true;
    }
  }}
  dropTargetOffset={5}
  placeholderRender={(node, { depth }) => (
    <Placeholder node={node} depth={depth} />
  )}
/>

Expected behaviour

I expect the dist/index.js file not to raise an error.

Reproduction method

Example: After logging out, log in again with another account.

Hello guys a quick fix will be nextjs/dynamic

First install…

npm i react-dnd-html5-backend

import dynamic from 'next/dynamic'

const { Tree } = {
  Tree: dynamic(() => import('@minoru/react-dnd-treeview').then((module) => module.Tree) , { ssr: false }),
}
const { DndProvider } = {
  DndProvider: dynamic(() => import('react-dnd').then((module) => module.DndProvider) , { ssr: false }),
}
import { HTML5Backend } from 'react-dnd-html5-backend'

After that use…

export default function Page() {
  const initialData = [
      {
        "id": 1,
        "parent": 0,
        "droppable": true,
        "text": "Folder 1"
      },
      {
        "id": 2,
        "parent": 1,
        "text": "File 1-1"
      },
      {
        "id": 3,
        "parent": 1,
        "text": "File 1-2"
      },
      {
        "id": 4,
        "parent": 0,
        "droppable": true,
        "text": "Folder 2"
      },
      {
        "id": 5,
        "parent": 4,
        "droppable": true,
        "text": "Folder 2-1"
      },
      {
        "id": 6,
        "parent": 5,
        "text": "File 2-1-1"
      }
    ]
  const [treeData, setTreeData] = useState(initialData)
  const handleDrop = (newTreeData) => setTreeData(newTreeData)

  return (
  <DndProvider backend={HTML5Backend} >
    <Tree
     tree={treeData}
     rootId={0}
     onDrop={handleDrop}
     render={(node, { depth, isOpen, onToggle }) => (
       <div style={{ marginLeft: depth * 10 }}>
         {node.droppable && (
           <span onClick={onToggle}>{isOpen ? "[-]" : "[+]"}</span>
         )}
         {node.text}
       </div>
     )}
   />
  </DndProvider>
  )
}

Thank you very much, works like a charm.
