Project Overview

TaskFlow Dashboard is a comprehensive task management solution designed to showcase modern frontend development skills. The application allows users to create, organize, and track tasks through an intuitive drag-and-drop interface.

The project was built from scratch using pure HTML, CSS, and JavaScript without any external libraries or frameworks, demonstrating proficiency in core web technologies and problem-solving abilities.

Key objectives included implementing seamless drag-and-drop functionality, creating a responsive design that works on all devices, and ensuring data persistence using the browser's local storage API.

Key Features

Drag & Drop Interface

Intuitive drag-and-drop functionality allowing users to move tasks between columns seamlessly. Built using native HTML5 Drag and Drop API with custom visual feedback.

Local Storage Persistence

All tasks are automatically saved to the browser's local storage, ensuring data persistence across sessions without requiring a backend server.

Fully Responsive Design

Optimized for all screen sizes using CSS Grid, Flexbox, and media queries. The interface adapts beautifully from desktop to mobile devices.

Interactive Notifications

Real-time feedback system with animated notifications that confirm user actions like task creation, deletion, or status changes.

Data Export

Export all tasks as JSON files for backup or migration purposes. Import functionality allows users to load sample data for demonstration.

Modern UI/UX

Clean, modern interface with smooth animations, hover effects, and a consistent color scheme using CSS custom properties.

Technology Stack

Built entirely with vanilla web technologies to demonstrate fundamental understanding of browser APIs and modern CSS.

// Drag and Drop Implementation
function setupDragAndDrop() {
    const taskLists = document.querySelectorAll('.task-list');
    
    taskLists.forEach(list => {
        list.addEventListener('dragover', handleDragOver);
        list.addEventListener('dragenter', handleDragEnter);
        list.addEventListener('drop', handleDrop);
    });
}

function handleDrop(e) {
    e.preventDefault();
    const taskId = e.dataTransfer.getData('text/plain');
    const newColumn = this.getAttribute('data-column');
    
    // Update task in data model
    const taskIndex = tasks.findIndex(task => task.id == taskId);
    if (taskIndex !== -1) {
        tasks[taskIndex].column = newColumn;
        saveTasks();
        renderAllTasks();
        showNotification(`Task moved to ${newColumn}!`);
    }
}
