🚀 Quick Start

Installation

npm install react-kanbanui
# or
yarn add react-kanbanui

Import Styles

IMPORTANT: You MUST import the CSS file for styles to work!

// Import the CSS file in your main app file (e.g., main.tsx, index.tsx, App.tsx)
import "react-kanbanui/dist/cjs/index.css";
// or for ESM
import "react-kanbanui/dist/esm/index.css";

// Then import the components
import { KanbanBoard, type IKanbanColumn } from "react-kanbanui";

Note: The CSS file includes all necessary styles - no need to install Tailwind CSS separately!

Basic Usage

import React, { useState } from "react";
import { KanbanBoard, IKanbanColumn } from "react-kanbanui";

const MyApp = () => {
  const [columns, setColumns] = useState<IKanbanColumn[]>([
    {
      id: "todo",
      title: "To Do",
      status: "todo",
      cards: [
        {
          id: "card-1",
          title: "Implement login",
          description: "Create user authentication system",
          priority: "high",
          status: "todo",
          assignee: "John Doe",
          tags: ["frontend", "auth"],
        },
      ],
    },
  ]);

  const handleColumnsChange = (newColumns: IKanbanColumn[]) => {
    setColumns(newColumns);
  };

  return (
    <KanbanBoard
      columns={columns}
      onColumnsChange={handleColumnsChange}
      theme="light"
      columnHeight="600px"
    />
  );
};

🎨 Styling

KanbanUI uses Tailwind CSS classes by default but can be fully customized:

<KanbanBoard
  columns={columns}
  useOwnStyles={true}
  className="my-custom-board"
  columnHeight="700px"
/>

🔧 Advanced Configuration

Column Limits

const columns: IKanbanColumn[] = [
  {
    id: "in-progress",
    title: "In Progress",
    status: "in-progress",
    maxCards: 3, // Limit to 3 cards
    cards: [],
  },
];

Custom Card Components

import { KanbanCard } from "react-kanbanui";

const CustomCard = ({ card, ...props }) => (
  <KanbanCard {...props} card={card} className="custom-card-style" />
);

🎯 Performance

KanbanUI is optimized for performance with:

• React.memo for component memoization
• useCallback for stable function references
• useMemo for expensive calculations
• Efficient drag state management
• Minimal re-renders during drag operations

See the Performance Guide for detailed testing instructions.

🎨 Theming

KanbanUI supports both light and dark themes:

// Light theme (default)
<KanbanBoard columns={columns} theme="light" />

// Dark theme
<KanbanBoard columns={columns} theme="dark" />
