# BookDate Implementation Status

## ✅ Completed Phases (1-5)

### Phase 1: Database Schema ✅
**Files:**
- `prisma/schema.prisma` - Added 3 models:
  - `BookDateConfig` - Per-user AI configuration (encrypted API keys)
  - `BookDateRecommendation` - Cached recommendations
  - `BookDateSwipe` - Swipe history for learning
  - Added relationships to User model

**To apply schema:**
```bash
docker-compose restart app
# Or manually: npx prisma db push && npx prisma generate
```

### Phase 2: Backend API - Configuration ✅
**Files created:**
- `src/app/api/bookdate/test-connection/route.ts` - Test AI provider & fetch models
- `src/app/api/bookdate/config/route.ts` - GET/POST/DELETE user config
- `src/app/api/admin/bookdate/toggle/route.ts` - Admin global toggle
- `src/app/api/bookdate/swipes/route.ts` - Clear swipe history

### Phase 3: Backend API - Recommendations ✅
**Files created:**
- `src/lib/bookdate/helpers.ts` - Complete helper functions:
  - `getUserLibraryBooks()` - Get Plex library books
  - `getUserRecentSwipes()` - Get swipe history
  - `buildAIPrompt()` - Generate AI prompt
  - `callAI()` - Call OpenAI/Claude APIs
  - `matchToAudnexus()` - Match recommendations to Audible
  - `isInLibrary()`, `isAlreadyRequested()`, `isAlreadySwiped()` - Filtering helpers
- `src/app/api/bookdate/recommendations/route.ts` - Get recommendations (cached or generate)

- `src/app/api/bookdate/undo/route.ts` - Undo last swipe
- `src/app/api/bookdate/generate/route.ts` - Force generate new batch

### Phase 4: Setup Wizard Integration ✅
**Files modified:**
- `src/app/setup/page.tsx` - Added BookDate as step 7 (now 9 total steps)
- `src/app/setup/steps/BookDateStep.tsx` - New setup step component
- `src/app/api/setup/complete/route.ts` - Save BookDate config during setup

### Phase 5: Settings Page ✅
**Files created:**
- `src/app/settings/page.tsx` - User settings page with:

## ⏳ Remaining Work (Phases 6-8)

### Phase 6: BookDate UI - Main Page & Components 🚧

#### 6.1 Install Dependencies
```bash
npm install react-swipeable framer-motion
```

#### 6.2 Files to Create

**Main BookDate Page:**
- `src/app/bookdate/page.tsx` - Main swipe interface page

**Components:**
- `src/components/bookdate/RecommendationCard.tsx` - Swipeable card component
- `src/components/bookdate/LoadingScreen.tsx` - Animated loading screen
- `src/components/bookdate/EmptyState.tsx` - Empty state when no recommendations

**Key Features:**
- Mobile: Touch swipe gestures (left/right/up)
- Desktop: Button controls
- Visual feedback during drag
- Confirmation toast for right swipes
- Undo button for left/up swipes
- Auto-request creation on right swipe + confirm

#### 6.3 Navigation Integration
Add BookDate tab to main navigation (conditional based on configuration):
- Modify `src/components/layout/Header.tsx` (or wherever nav is)
- Check `/api/bookdate/config` to show/hide tab
- Only show if `config.isVerified && config.isEnabled`

### Phase 7: Integration & Polish 🚧

#### 7.1 Plex Library Integration
**File:** `src/lib/bookdate/helpers.ts`

Update `getUserLibraryBooks()`:
- Query Plex API directly (not just database cache)
- For 'listened' scope: Calculate `viewOffset / duration > 0.25`
- For 'rated' scope: Fetch user ratings from Plex
- Extract genres from Plex metadata
- Fallback to database if Plex API fails

#### 7.2 Audnexus Matching Enhancement
**File:** `src/lib/bookdate/helpers.ts`

Update `matchToAudnexus()`:
- If not in `AudibleCache`, query Audnexus API directly
- Implement fuzzy matching (Levenshtein distance < 3)
- Handle multiple results (pick best by rating/popularity)
- Cache new matches to `AudibleCache`

#### 7.3 Request Integration
**File:** `src/app/api/bookdate/swipe/route.ts`

Already implemented:
- ✅ Creates audiobook record if doesn't exist
- ✅ Creates request on right swipe (if not marked as known)
- ✅ Links to existing audiobook by ASIN

### Phase 8: Testing & Verification 🚧

#### 8.1 Database Testing
- [ ] Build Docker image: `docker-compose build`
- [ ] Start containers: `docker-compose up -d`
- [ ] Check logs: `docker-compose logs -f app`
- [ ] Verify Prisma migration: Check PostgreSQL tables
- [ ] Test encrypted API key storage

#### 8.2 API Testing (Manual)
Use Postman/Thunder Client or curl:

```bash
# Test connection
curl -X POST http://localhost:3030/api/bookdate/test-connection \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"provider":"openai","apiKey":"sk-..."}'

# Save config
curl -X POST http://localhost:3030/api/bookdate/config \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"provider":"openai","apiKey":"sk-...","model":"gpt-4o","libraryScope":"full"}'

# Get recommendations
curl http://localhost:3030/api/bookdate/recommendations \
  -H "Authorization: Bearer YOUR_TOKEN"
```

#### 8.3 UI Testing
- [ ] Setup wizard: Complete step 7 (BookDate)
- [ ] Settings page: Save/update config
- [ ] BookDate tab: Visibility based on config
- [ ] Swipe gestures: Test on mobile and desktop
- [ ] Loading states: Check animations
- [ ] Error handling: Test invalid API keys, network errors

## 📋 Quick Implementation Guide for Remaining Work

### Step 1: Create BookDate Main Page

Create `src/app/bookdate/page.tsx`:

```typescript
'use client';

import { useState, useEffect } from 'react';
import { useRouter } from 'next/navigation';
import { Header } from '@/components/layout/Header';
import { RecommendationCard } from '@/components/bookdate/RecommendationCard';
import { LoadingScreen } from '@/components/bookdate/LoadingScreen';

export default function BookDatePage() {
  const [recommendations, setRecommendations] = useState<any[]>([]);
  const [loading, setLoading] = useState(true);
  const [error, setError] = useState<string | null>(null);
  const [currentIndex, setCurrentIndex] = useState(0);
  const router = useRouter();

  useEffect(() => {
    loadRecommendations();
  }, []);

  const loadRecommendations = async () => {
    setLoading(true);
    try {
      const accessToken = localStorage.getItem('accessToken');
      const response = await fetch('/api/bookdate/recommendations', {
        headers: { 'Authorization': `Bearer ${accessToken}` }
      });

      const data = await response.json();

      if (!response.ok) {
        setError(data.error);
        return;
      }

      setRecommendations(data.recommendations);
    } catch (error: any) {
      setError(error.message);
    } finally {
      setLoading(false);
    }
  };

  const handleSwipe = async (action: 'left' | 'right' | 'up', markedAsKnown = false) => {
    const recommendation = recommendations[currentIndex];

    try {
      const accessToken = localStorage.getItem('accessToken');
      await fetch('/api/bookdate/swipe', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
          'Authorization': `Bearer ${accessToken}`
        },
        body: JSON.stringify({
          recommendationId: recommendation.id,
          action,
          markedAsKnown
        })
      });

      setCurrentIndex(currentIndex + 1);

      // Check if we need to load more
      if (currentIndex + 1 >= recommendations.length) {
        // Show empty state or load more
      }
    } catch (error) {
      console.error('Swipe error:', error);
    }
  };

  if (loading) {
    return <LoadingScreen />;
  }

  if (error) {
    return (
      <div className="min-h-screen bg-gray-50 dark:bg-gray-900">
        <Header />
        <div className="flex flex-col items-center justify-center min-h-[80vh]">
          <h2 className="text-2xl font-bold mb-4">Could not load recommendations</h2>
          <p className="text-gray-600 mb-4">{error}</p>
          <div className="flex gap-4">
            <button
              onClick={loadRecommendations}
              className="px-6 py-2 bg-blue-600 text-white rounded-lg hover:bg-blue-700"
            >
              Try Again
            </button>
            <button
              onClick={() => router.push('/settings')}
              className="px-6 py-2 border border-gray-300 rounded-lg hover:bg-gray-50"
            >
              Go to Settings
            </button>
          </div>
        </div>
      </div>
    );
  }

  if (currentIndex >= recommendations.length) {
    return (
      <div className="min-h-screen bg-gray-50 dark:bg-gray-900">
        <Header />
        <div className="flex flex-col items-center justify-center min-h-[80vh]">
          <h2 className="text-2xl font-bold mb-4">You've seen all recommendations!</h2>

            >
              Get More
            </button>
            <button
              onClick={() => router.push('/')}
              className="px-6 py-2 border border-gray-300 rounded-lg hover:bg-gray-50"
            >
              Go Home
            </button>
          </div>
        </div>
      </div>
    );
  }

  const currentRec = recommendations[currentIndex];

  return (
    <div className="min-h-screen bg-gray-50 dark:bg-gray-900">
      <Header />
      <div className="flex flex-col items-center justify-center min-h-[80vh] p-4">
        <RecommendationCard
          recommendation={currentRec}
          onSwipe={handleSwipe}
        />
      </div>
    </div>
  );
}
```

### Step 2: Create Recommendation Card Component

Install dependencies first:
```bash
npm install react-swipeable
```

Create `src/components/bookdate/RecommendationCard.tsx`:

```typescript
'use client';

import { useState } from 'react';
import Image from 'next/image';
import { useSwipeable } from 'react-swipeable';

interface RecommendationCardProps {
  recommendation: any;
  onSwipe: (action: 'left' | 'right' | 'up', markedAsKnown?: boolean) => void;
}

export function RecommendationCard({ recommendation, onSwipe }: RecommendationCardProps) {
  const [showToast, setShowToast] = useState(false);
  const [dragOffset, setDragOffset] = useState({ x: 0, y: 0 });

  const handleSwipeRight = () => {
    setShowToast(true);
  };

  const handleToastAction = (action: 'request' | 'known' | 'cancel') => {
    setShowToast(false);
    if (action === 'request') {
      onSwipe('right', false);
    } else if (action === 'known') {
      onSwipe('right', true);
    }
  };

  const swipeHandlers = useSwipeable({
    onSwipedLeft: () => onSwipe('left'),
    onSwipedRight: handleSwipeRight,
    onSwipedUp: () => onSwipe('up'),
    onSwiping: (eventData) => {
      setDragOffset({ x: eventData.deltaX, y: eventData.deltaY });
    },
    trackMouse: true
  });

  return (
    <>
      <div
        {...swipeHandlers}
        className="relative w-full max-w-md bg-white dark:bg-gray-800 rounded-2xl shadow-2xl overflow-hidden transition-transform"
        style={{
          transform: `translate(${dragOffset.x}px, ${dragOffset.y}px)`,
          transition: dragOffset.x === 0 ? 'transform 0.3s' : 'none'
        }}
      >
        {/* Drag overlay indicators */}
        {dragOffset.x > 50 && (
          <div className="absolute inset-0 bg-green-500 bg-opacity-30 flex items-center justify-center">

        <div className="w-full h-96 relative bg-gray-200 dark:bg-gray-700">
          {recommendation.coverUrl ? (

          </div>
        </div>
      )}
    </>
  );
}
```

### Step 3: Create Loading Screen Component

Create `src/components/bookdate/LoadingScreen.tsx`:

```typescript
export function LoadingScreen() {
  return (
    <div className="flex flex-col items-center justify-center min-h-screen bg-gray-50 dark:bg-gray-900">
      <div className="relative w-64 h-96 mb-8">
        {/* Animated book cards */}
        <div className="absolute inset-0 bg-gradient-to-br from-blue-500 to-purple-500 rounded-lg animate-pulse" />
        <div
          className="absolute inset-0 bg-gradient-to-br from-green-500 to-teal-500 rounded-lg animate-bounce"
          style={{ animationDelay: '0.2s' }}
        />
        <div
          className="absolute inset-0 bg-gradient-to-br from-orange-500 to-pink-500 rounded-lg animate-ping"
          style={{ animationDelay: '0.4s' }}
        />
      </div>
      <p className="text-xl text-gray-600 dark:text-gray-400">
        Finding your next great listen...
      </p>
    </div>
  );
}
```

### Step 4: Add Navigation Link

Modify your main navigation component (likely `src/components/layout/Header.tsx`):

```typescript
// Add to navigation links
const [showBookDate, setShowBookDate] = useState(false);

useEffect(() => {
  async function checkBookDate() {
    const accessToken = localStorage.getItem('accessToken');
    const response = await fetch('/api/bookdate/config', {
      headers: { 'Authorization': `Bearer ${accessToken}` }
    });
    const data = await response.json();
    setShowBookDate(data.config && data.config.isVerified && data.config.isEnabled);
  }
  checkBookDate();
}, []);

// In your navigation JSX:
{showBookDate && (
  <Link href="/bookdate" className="...">
    BookDate
  </Link>
)}
```
