├── requests/ # Request cards, status
├── layout/ # Header, nav, footer
└── ui/ # Reusable primitives
```
## Key Components
**Layout**
- **Header** - Top nav, search input, user menu
- **Sidebar** - Admin side nav
- **Footer** - Version, links
**Audiobooks**
- **AudiobookCard** ✅ - Cover, title, author, narrator, duration, request button, clickable to open details modal. Shows "Requested by [username]" when someone else has requested the book, "Requested" when current user has requested it
- **AudiobookGrid** - Responsive grid (1/2/3/4 cols)
- **AudiobookDetailsModal** ✅ - Full-screen modal with comprehensive metadata (description, genres, rating, release date, narrator, request functionality). Shows requesting user's name when applicable
**Requests**
- **RequestCard** ✅ - Cover, title, author, status badge, progress bar, timestamps, action buttons (cancel, manual search, interactive search)
- **StatusBadge** - Color-coded status (pending=yellow, searching=blue, downloading=purple, downloaded=green, processing=orange, available=green, completed=green, failed=red, warn=orange, cancelled=gray). Shows "Initializing..." when downloading with 0% progress (fetching torrent info), "Downloading" when progress > 0%
- **ProgressBar** - Animated fill with percentage
- **InteractiveTorrentSearchModal** ✅ - Responsive table of ranked torrent results, uses ConfirmModal for downloads, hides columns on smaller screens (size on mobile, seeds on tablet, indexer on desktop)
- Active indicator: "Setting up..." with spinner when progress = 0%, "Active" with pulsing dot when progress > 0%
**Forms**
- **SearchBar** - Debounced input with suggestions
- **Button** - Variants (primary/secondary/outline/ghost/danger), sizes (sm/md/lg), loading state
- **Input** - Label, error display, validation, icons
- **Select** - Custom styling, search/filter
- **Modal** ✅ - Dialog overlay with backdrop, sizes (sm/md/lg/xl/full), ESC to close, body scroll lock
- **ConfirmModal** ✅ - Confirmation dialog with customizable title, message, buttons, loading state, and variant (primary/danger)
- **Pagination** ✅ - Traditional page navigation with prev/next buttons, smart ellipsis (shows 1...4 5 6...10)
- **StickyPagination** ✅ - Minimal floating pill at bottom center with prev/next arrows, quick jump input, section label. Shows/hides based on section visibility (IntersectionObserver). Rounded-full design, backdrop blur, subtle shadow, auto-scroll on page change
**Auth**
- **ProtectedRoute** ✅ - Auth check, loading state, redirects, admin role support
- **LoginPage** ✅ - Full-screen design, floating covers, Plex OAuth popup
**Admin**
- **MetricCard** - Icon, label, value, trend
- **DataTable** - Sorting, filtering, pagination
- **Chart** - Line/bar/pie
## Pages Implemented ✅
**Homepage** (`/`)
- Popular Audiobooks and New Releases sections with distinct visual separation
- Sticky section headers with rounded-2xl design matching section card aesthetic
- Gradient accent bars for each section (blue/purple for Popular, emerald/teal for New Releases)
- Headers use rounded cards (bg-white/90 dark:bg-gray-800/90) with backdrop blur
- Section content wrapped in semi-transparent rounded cards (bg-white/40 dark:bg-gray-800/40)
- Cohesive rounded design language throughout (rounded-2xl on headers and containers)
- Floating pagination pill at bottom center of viewport
- Minimal design: section label | ← | Page X of Y | →
- Quick jump input (type page number + Enter)
- Auto-shows when scrolling through a section (IntersectionObserver)

# Login Page
**Status:** ✅ Implemented | Real floating book covers with professional animations
Stylized entry point with Plex OAuth integration, animated floating popular audiobook covers, and prominent "Login with Plex" CTA.
## Design
- Full-screen immersive experience with gradient background
- Centered hero with login button
- Animated floating real audiobook covers (popular releases)
- **100 randomly positioned covers** with varied sizes, animations, and depth
- Multi-layer depth effect with z-index layering (0-20)
- Dark theme optimized with glassmorphism card
- Professional streaming service aesthetic
## Authentication Flow
1. User visits protected route → redirected to `/login`
2. Clicks "Login with Plex"
3. `POST /api/auth/plex/login` → requests PIN
4. Opens Plex OAuth in popup
5. Polls `/api/auth/plex/callback` for authorization
6. User authorizes in Plex popup
7. Callback receives auth token
8. Creates/updates user in DB
9. Returns JWT tokens
10. Client stores tokens in localStorage
11. Redirects to originally requested page or homepage
## Book Covers
**Data Source:** `GET /api/audiobooks/covers`
- Returns up to 200 popular audiobook covers
- Uses cached thumbnails from `audible_cache` table
- Shuffled on each request for variety
- Fallback to placeholder elements if API fails
**Display:**
- **100 covers** shown simultaneously for immersive experience
- Varied sizes: 80-160px wide (1.5 aspect ratio)
- Opacity range: 0.15-0.35 for subtle layering and depth
- Staggered animation delays (0-10s) for natural movement
- Z-index layering (0-20) for depth perception
- Programmatic positioning using seeded random for consistency
- Lazy loading (first 10 eager, rest lazy) for performance
- Hover pauses animation and scales for interaction
**Positioning Algorithm:**
- Seeded random function ensures consistent positions per cover index
- Random distribution across full viewport (0-100% both axes)
- Each cover gets unique: size, position, opacity, delay, z-index, animation type
- Seed multipliers (7, 13, 17, 23, 29, 31) prevent pattern repetition
- Math.sin() based pseudo-random for deterministic results
## State
```typescript
interface LoginPageState {
isLoggingIn: boolean;
error: string | null;
pinId: number | null;
authWindow: Window | null;
bookCovers: BookCover[];
showAdminLogin: boolean;
adminUsername: string;
adminPassword: string;
}
interface BookCover {
asin: string;
title: string;
author: string;
coverUrl: string;
}
```
## Error Handling
**Popup Blocked:** "Popup was blocked. Please allow popups."
**Login Timeout:** 2 min polling timeout
**Plex Unavailable:** "Plex services currently unavailable."
**Covers Fail:** Silent fallback to placeholder gradient elements
## Animations
Three animation speeds with realistic floating motion:
```css
@keyframes float-slow {
/* 22s cycle with 4 keyframes */
0%, 100% { transform: translateY(0) translateX(0) rotate(0deg) scale(1); }
25% { transform: translateY(-25px) translateX(15px) rotate(2deg) scale(1.03); }
50% { transform: translateY(-35px) translateX(25px) rotate(4deg) scale(1.05); }
75% { transform: translateY(-20px) translateX(-10px) rotate(-2deg) scale(1.02); }
}
@keyframes float-medium {
/* 16s cycle with 3 keyframes */
0%, 100% { transform: translateY(0) translateX(0) rotate(0deg) scale(1); }
33% { transform: translateY(-30px) translateX(-20px) rotate(-3deg) scale(1.04); }
66% { transform: translateY(-15px) translateX(10px) rotate(3deg) scale(1.02); }
}
@keyframes float-fast {
/* 12s cycle with 2 keyframes */
0%, 100% { transform: translateY(0) translateX(0) rotate(0deg) scale(1); }
50% { transform: translateY(-28px) translateX(18px) rotate(5deg) scale(1.06); }
}
```
**Features:**
- Scale transformations (1.02-1.06) for depth
- Rotation (-5° to +5°) for natural movement
- X/Y translation for floating effect
- Hover pauses animation
- Shadow-2xl for 3D depth
## Security
- Tokens in localStorage (access 1hr, refresh 7d)
- Tokens cleared on logout
- OAuth state parameter validation
- SameSite cookie attributes
## Tech Stack
- Next.js 14+ Client Component
- Tailwind CSS with custom animations
- Plex OAuth via AuthContext

# Route Authentication and Protection
**Status:** ✅ Implemented | Token expiry validation, auto-refresh, 401 handling
Authentication and authorization system protecting routes, ensuring only authenticated users can access protected pages.
## Protection Strategy
**Client-Side:** React components check auth state, redirect to login if needed, preserve original URL
**Server-Side:** API routes validate JWT tokens via middleware, return 401/403 for unauthorized
## Routes
**Public:** `/login`, `/setup`, `/api/*` (handle auth independently)
**Protected:** `/` (home), `/search`, `/requests`, `/profile`
**Admin:** `/admin/*` - requires admin role
## ProtectedRoute Component
**Location:** `src/components/auth/ProtectedRoute.tsx`
**Behavior:**
1. Check auth state from AuthContext
2. Optionally check admin role
3. Show loading spinner while checking
4. Redirect to `/login` if unauthenticated
5. Redirect to `/` if admin required but not admin
6. Render children if authorized
## API Middleware
**Location:** `src/lib/middleware/auth.ts`
**Server-side validation:**
- `requireAuth()` - validates JWT, adds user to request
- `requireAdmin()` - checks admin role, chains after requireAuth
- Returns 401 for invalid/expired tokens
- Returns 403 for insufficient permissions
## Token Management
**Location:** `src/contexts/AuthContext.tsx`, `src/lib/utils/jwt-client.ts`
**Token Validation on Mount:**
- Decodes access token to check expiry
- If expired but refresh token valid → auto-refresh
- If both expired → clear storage, redirect to login
- Cross-tab logout sync via storage events
**Auto-Refresh (5 mins before expiry):**
```typescript
const refreshTimeMs = getRefreshTimeMs(token);
setTimeout(() => refreshToken(), refreshTimeMs);
```
**Schedule:**
- After login → schedule first refresh
- After token refresh → schedule next refresh
- Cleanup on logout or unmount
## API Client with 401 Handling
**Location:** `src/lib/utils/api.ts`
**fetchWithAuth():**
- Adds Authorization header automatically
- Catches 401 responses
- Attempts token refresh once
- Retries original request with new token
- Logs out if refresh fails
- Prevents duplicate refresh requests
**Usage:**
```typescript
// In hooks/components
import { fetchWithAuth, fetchJSON } from '@/lib/utils/api';
// GET request
const response = await fetchWithAuth('/api/requests');
// POST with JSON
const data = await fetchJSON('/api/requests', {
method: 'POST',
body: JSON.stringify({ audiobook }),
});
```
## Error Handling
**401 Unauthorized:**
1. Attempt token refresh automatically
2. Retry original request with new token
3. If still 401 or refresh fails → logout (clears storage + redirects to /login)
**403 Forbidden:**
- Valid token but insufficient permissions
- Return error, don't logout
## Logout Behavior
**Global redirect on logout:**
- `logout()` from AuthContext → clears storage + redirects to /login
- API 401 errors → `performLogout()` → clears storage + redirects to /login
- Cross-tab logout → storage event triggers redirect to /login
- Ensures user never remains on authenticated pages after logout
## Cross-Tab Sync
**Storage Events:**
- Logout in one tab → logout + redirect to login in all tabs
- Login in one tab → sync auth state to all tabs
- Prevents stale sessions across browser tabs
## Security
- Never log tokens
- HTTPS only in production
- Short access token expiry (1hr)
- Auto-refresh 5 mins before expiry
- Token expiry validation on mount
- Prevent duplicate refresh requests
- SameSite cookies for CSRF protection
- Client-side token decode (signature verified server-side only)
## Fixed Issues
- **Expired tokens not logging out:** Added token expiry validation on mount
- **No auto-refresh:** Scheduled refresh 5 mins before token expires
- **401 errors not handled:** Added global 401 interceptor with token refresh
- **Logged-out sessions persisting:** Token validation clears expired sessions immediately
- **Logout not redirecting:** Added automatic redirect to /login on all logout scenarios (manual, API 401, cross-tab)
## Tech Stack
- Next.js 14+ App Router
- JWT via AuthContext
- React Context API
- Custom fetch wrapper for 401 handling
