Inspiration
I wanted to build a project that goes beyond a basic beginner app and helps users manage tasks in a more structured and practical way. A simple todo list is useful, but real-life task management needs priorities, categories, and deadlines. This motivated me to build an advanced React Todo application with clean UI and meaningful features.
What it does
This is an advanced Todo application built using React, JavaScript, HTML, and CSS.
Users can:
- Add tasks with priority, category, and due date
- Edit tasks (including priority, category, and due date)
- Mark tasks as completed using toggle
- Delete individual tasks
- Clear all tasks at once
- See overdue tasks highlighted automatically
- Persist tasks using localStorage, so data is not lost on refresh
- Use the app smoothly on both desktop and mobile devices due to responsive design
How I built it
- Used React functional components and useState / useEffect hooks
- Managed application state efficiently for tasks and editing mode
- Implemented localStorage to save and retrieve todos
- Used date comparison logic to detect and highlight overdue tasks
- Styled the UI using pure CSS with Flexbox and media queries
- Kept the UI clean, minimal, and user-friendly
Challenges I ran into
- Managing edit state for individual todo items without breaking the main state
- Handling date comparison correctly to avoid false overdue highlights
- Preventing unnecessary re-renders while syncing with localStorage
- Making the UI responsive while keeping it simple and readable
What I learned
- Better understanding of React state management
- How to structure components cleanly for scalability
- Practical usage of localStorage with React
- Implementing real-world features like deadlines and priority handling
- Improving UI/UX with small but meaningful design decisions
What's next
In the future, I would like to add:
- Filters (by priority, category, completed status)
- Sorting tasks by due date or priority
- Animations for better user experience
- Optional backend integration for user authentication
