Overview

This solution implements a Task Manager application using React, TypeScript, and Tailwind CSS. The application allows users to create, manage, and filter tasks with a clean and responsive interface.

Overview

I've implemented a fully functional Task Manager application with React, TypeScript, and Tailwind CSS. The application allows users to create, view, manage, and filter tasks with a responsive UI and persistent storage.

Key Improvements

Bug Fixes

• Fixed task filtering functionality
• Resolved task deletion UI update issues
• Corrected styling inconsistencies across components
• Addressed all TypeScript warnings and errors

Enhanced Architecture

• Implemented custom useTasks hook for centralized state management
• Created proper TypeScript types and interfaces
• Separated UI components from business logic
• Established consistent file structure and naming conventions

UI/UX Enhancements

• Added confirmation dialog for task deletion
• Created reusable Button component with variants
• Implemented responsive design with Tailwind breakpoints
• Redesigned task status filters as a button group

Added Features

• Persistent storage using localStorage
• Comprehensive unit tests
• CI/CD pipeline for automated deployment
• Responsive layout for all device sizes

Technical Implementation

State Management

// src/hooks/useTasks.ts
export const useTasks = () => {
  const [tasks, setTasks] = useState<Task[]>(getStoredTasks());
  
  // State management with proper callbacks
  const addTask = useCallback((title: string) => {
    setTasks(prevTasks => [...prevTasks, { 
      id: Date.now(),
      title, 
      completed: false 
    }]);
  }, []);
  
  // Persisting to localStorage
  useEffect(() => {
    localStorage.setItem(STORAGE_KEY, JSON.stringify(tasks));
  }, [tasks]);
  
  return { tasks, addTask, deleteTask, toggleTask, filteredTasks };
};

Component Architecture
// Component hierarchy```

// TaskManager (main container)
// ├── TaskForm (add new tasks)
// ├── TaskStatusFilter (filter controls)
// └── TaskList (displays tasks)
// └── TaskItem (individual task)
// └── DeleteConfirmationDialog (confirmation for deletion)

### TypeScript Integration

// src/types/index.ts
export interface Task {
id: number;
title: string;
completed: boolean;
}

export type TaskFilterStatus = 'all' | 'completed' | 'pending';

export interface TaskItemProps {
task: Task;
onToggle: (id: number) => void;
onDelete: (id: number) => void;
}

### Testing & Deployment

- Implemented unit tests for components, hooks, and utilities
- Set up automated CI/CD pipeline on Render.com
- Configured build process to run tests before deployment

### Future Improvements

- Task categories/tags
- Due dates and priority levels
- Search functionality
- Drag-and-drop reordering
- Authentication and sharing capabilities
