reactjsHow can I create a Kanban board using ReactJS?

Kanban boards are a popular way to manage tasks, and ReactJS is a great tool to create them. To create a Kanban board with ReactJS, you can use a library such as react-beautiful-dnd.

First, you need to install the library with:

npm install react-beautiful-dnd

Then, you can create a Kanban board using the following code:

import React, { useState } from 'react'
import { DragDropContext, Droppable, Draggable } from 'react-beautiful-dnd'

const KanbanBoard = () => {
  const [items, setItems] = useState([
    { id: 'item-1', content: 'Task 1' },
    { id: 'item-2', content: 'Task 2' },
    { id: 'item-3', content: 'Task 3' },
  ])

  const onDragEnd = (result) => {
    const { destination, source, draggableId } = result

    if (!destination) {
      return
    }

    if (
      destination.droppableId === source.droppableId &&
      destination.index === source.index
    ) {
      return
    }

    const start = items[source.index]
    const finish = items[destination.index]

    setItems([
      ...items.slice(0, source.index),
      finish,
      ...items.slice(source.index + 1, destination.index),
      start,
      ...items.slice(destination.index + 1),
    ])
  }

  return (
    <DragDropContext onDragEnd={onDragEnd}>
      <Droppable droppableId="droppable">
        {(provided) => (
          <div
            {...provided.droppableProps}
            ref={provided.innerRef}
          >
            {items.map((item, index) => (
              <Draggable key={item.id} draggableId={item.id} index={index}>
                {(provided) => (
                  <div
                    ref={provided.innerRef}
                    {...provided.draggableProps}
                    {...provided.dragHandleProps}
                  >
                    {item.content}
                  </div>
                )}
              </Draggable>
            ))}
            {provided.placeholder}
          </div>
        )}
      </Droppable>
    </DragDropContext>
  )
}

export default KanbanBoard

This code creates a Kanban board with three tasks ("Task 1", "Task 2", and "Task 3"). The onDragEnd function is used to update the state when an item is moved. The Draggable component is used to wrap each task item, allowing it to be dragged and dropped.

The output of this code is a Kanban board with three tasks that can be reordered by dragging and dropping them.

Parts of the code:

• npm install react-beautiful-dnd: Installs the react-beautiful-dnd library.
• DragDropContext: Wraps the Kanban board and provides the drag and drop context.
• Droppable: Wraps the list of tasks and provides the droppable context.
• Draggable: Wraps each task item and provides the draggable context.
• onDragEnd: Updates the state when an item is moved.
