# Scheduling Component Refactoring Summary

## Overview

The `Scheduling.tsx` file (originally 1832 lines) has been refactored into a modular structure with reusable components, hooks, and better organization.

## New Structure

```
scheduling-remote/src/components/
├── Scheduling.tsx                          # Backward compatibility re-export
└── scheduling/
    ├── types.ts                            # Shared types and interfaces
    ├── Scheduling.tsx                      # Main router component (~100 lines)
    ├── AvailabilityCalendar.tsx            # Availability calendar component
    ├── ui/                                 # Reusable UI components
    │   ├── BackButton.tsx                 # Back navigation button
    │   ├── SchedulingCard.tsx             # Card component for main view
    │   ├── TimeSlotModal.tsx              # Modal for adding time slots
    │   └── DropdownCurtain.tsx             # Reusable dropdown/accordion
    ├── views/                              # Main view components
    │   ├── ViewSchedule.tsx                # View schedule component
    │   ├── IndicateAvailability.tsx        # Indicate availability view
    │   └── ScheduleExperimentImpl.tsx      # Temporary wrapper (TODO: further refactor)
    └── hooks/                              # Custom hooks
        └── useConductors.ts                # Conductor management hook
```

## What Was Extracted

### 1. **Shared Types** (`types.ts`)
- `CalendarEvent` interface
- `SchedulingProps` interface
- `SchedulingView` type
- `ScheduledRepetition` interface
- Re-exports of service types

### 2. **Reusable UI Components** (`ui/`)
- **BackButton**: Consistent back navigation
- **SchedulingCard**: Reusable card component for the main scheduling view
- **TimeSlotModal**: Modal for adding/editing time slots
- **DropdownCurtain**: Reusable accordion/dropdown component

### 3. **View Components** (`views/`)
- **ViewSchedule**: Complete schedule view (simplified, placeholder)
- **IndicateAvailability**: Wrapper for availability calendar
- **ScheduleExperimentImpl**: Temporary wrapper (original implementation still in old file)

### 4. **Custom Hooks** (`hooks/`)
- **useConductors**: Manages conductor data, selection, colors, and availability

### 5. **Main Components**
- **Scheduling.tsx**: Main router component (reduced from ~220 lines to ~100 lines)
- **AvailabilityCalendar.tsx**: Extracted availability calendar (moved from inline component)

## Benefits

1. **Maintainability**: Each component has a single, clear responsibility
2. **Reusability**: UI components can be reused across different views
3. **Testability**: Smaller units are easier to test in isolation
4. **Readability**: Easier to understand and navigate the codebase
5. **Organization**: Clear separation of concerns

## File Size Reduction

- **Original Scheduling.tsx**: 1832 lines
- **New main Scheduling.tsx**: ~100 lines (95% reduction)
- **Total new structure**: Better organized across multiple focused files

## Backward Compatibility

The original `Scheduling.tsx` file is maintained for backward compatibility and re-exports the new modular component. The `ScheduleExperiment` function is still exported from the original file location.

## TODO / Future Improvements

1. **Further refactor ScheduleExperiment**:
   - Extract into smaller subcomponents (ConductorPanel, ExperimentPhasePanel, etc.)
   - Create additional hooks (useExperimentPhases, useScheduling, useCalendarEvents)
   - Move implementation from old file to new structure

2. **Additional reusable components**:
   - Experiment item component
   - Repetition item component
   - Calendar controls component

3. **Testing**:
   - Add unit tests for extracted components
   - Add integration tests for hooks

## Migration Notes

- All imports from `./components/Scheduling` continue to work
- The new structure is in `./components/scheduling/`
- No breaking changes to the public API
