The Challenge

The goal was to build a modern todo application that:

• Supports adding, completing, and deleting todos
• Allows filtering by all, active, or completed todos
• Clears all completed todos at once
• Persists tasks in local storage
• Supports light and dark themes with toggle functionality
• Reorders todos via drag-and-drop
• Provides a responsive layout and hover states for interactive elements

The Solution

The application was built using React and TypeScript, focusing on predictable state updates and intuitive interactions. Key implementation details:

• State management with React hooks
• Drag-and-drop functionality for reordering tasks
• Local storage integration for task persistence
• Tailwind CSS for layout, styling, and responsiveness
• Reusable components for maintainable code
• Light and dark theme support with toggle
• Responsive design and hover states for all interactive elements

The Outcome

The final result is a lightweight, responsive, and interactive todo app that performs well and feels intuitive to use. Through this project, I strengthened my understanding of:

• Managing complex UI state in React
• Type-safe component and state design with TypeScript
• Implementing drag-and-drop interactions
• Persisting client-side data with local storage
• Theme toggling and responsive design patterns
