# Create foundational components and data persistence - Summary

## What Was Accomplished

This plan successfully implemented the core components and data persistence layer for the weekly todo list application. The following key items were completed:

1. **Component Architecture**:
   - Created the core component structure with dedicated directories for components, hooks, and utilities
   - Defined the Task type with all required properties (id, title, date, description, completed, category)
   - Established the component hierarchy for CalendarGrid, TaskCard, and NavigationControls

2. **Core Components Implementation**:
   - Implemented CalendarGrid component showing 7-day weekly view with proper date handling
   - Created TaskCard component with editing capabilities and complete/incomplete toggle
   - Built NavigationControls component with previous/next week functionality

3. **Data Persistence**:
   - Developed localStorage persistence functions for saving and loading tasks
   - Integrated data persistence with the calendar grid component
   - Ensured tasks persist between browser sessions

4. **Drag-and-Drop Functionality**:
   - Implemented drag-and-drop capabilities using react-dnd
   - Enabled users to move tasks between days in the calendar view

## Technical Details

The implementation includes:
- CalendarGrid.tsx component that displays a weekly view organized by day
- TaskCard.tsx component that represents individual tasks with editing capabilities
- NavigationControls.tsx component for week navigation
- taskPersistence.ts library for localStorage integration
- Proper TypeScript interfaces for task data structure
- Date handling using date-fns library

## Integration Points

The components are properly integrated:
- CalendarGrid coordinates with TaskCard for rendering tasks
- CalendarGrid connects to navigation controls for week switching
- All components communicate via props for data flow
- Data persists between sessions using localStorage

## Next Steps

With the foundational components and data persistence in place, the application now has:
- A functional weekly calendar view
- Ability to add, edit, and delete tasks
- Drag-and-drop functionality between days
- Local storage persistence for tasks
- Week navigation controls

These foundations enable the implementation of additional features in subsequent phases while maintaining a stable, working prototype.
