🚀 Quick Start

import React, { useState } from 'react';
import { TaskDashboard, TaskManager } from '@bernierllc/task-ui';

function MyTaskApp() {
  const [tasks, setTasks] = useState([
    {
      id: '1',
      title: 'Design new landing page',
      description: 'Create mockups and wireframes for the new product landing page',
      status: 'in-progress' as const,
      priority: 'high' as const,
      dueDate: '2025-01-15',
      tags: ['design', 'frontend'],
      assignedTo: { id: '1', name: 'Alice Johnson', email: '[email protected]' },
      createdAt: '2025-01-10T09:00:00Z',
      updatedAt: '2025-01-10T09:00:00Z'
    }
  ]);

  const handleTaskUpdate = (taskId: string, updates: any) => {
    setTasks(prev => prev.map(task => 
      task.id === taskId 
        ? { ...task, ...updates, updatedAt: new Date().toISOString() }
        : task
    ));
  };

  const handleTaskCreate = (newTask: any) => {
    const task = {
      ...newTask,
      id: Date.now().toString(),
      createdAt: new Date().toISOString(),
      updatedAt: new Date().toISOString()
    };
    setTasks(prev => [...prev, task]);
  };

  const handleTaskDelete = (taskId: string) => {
    setTasks(prev => prev.filter(task => task.id !== taskId));
  };

  return (
