 ## Configuración y despliegue
 
+### Configuración de variables de entorno
+
+Para configurar las credenciales de las APIs externas en Quasar, sigue estos pasos:
+
+#### 1. Archivo `.env`
+
+El archivo [`backend/.env`](../../backend/.env) contiene las variables de entorno necesarias. Este archivo **NO** debe ser commiteado al repositorio (ya está incluido en [`.gitignore`](../../.gitignore)).
+
+#### 2. Variables requeridas
+
+Añade las siguientes variables a tu archivo [`backend/.env`](../../backend/.env):
+
+```bash
+# IGDB (Internet Game Database)
+IGDB_CLIENT_ID=your_igdb_client_id_here
+IGDB_CLIENT_SECRET=your_igdb_client_secret_here
+
+# RAWG Video Games Database
+RAWG_API_KEY=your_rawg_api_key_here
+
+# TheGamesDB
+THEGAMESDB_API_KEY=your_thegamesdb_api_key_here
+```
+
+#### 3. Archivo de ejemplo
+
+El archivo [`backend/.env.example`](../../backend/.env.example) contiene todas las variables de entorno disponibles con sus descripciones. Úsalo como referencia cuando configures tu entorno.
+
+#### 4. Instrucciones detalladas por API
+
+Consulte la sección [Obtención de claves](#obtención-de-claves) para instrucciones detalladas sobre cómo obtener cada credencial:
+

+**Características:**
+
+- Muestra la portada del juego
+- Campos editables: título, descripción, condición, plataforma
+- Botón para guardar el juego en la biblioteca
+
+#### API Client
+
+Funciones disponibles en `src/lib/api.ts`:
+
+```typescript
+// Buscar juegos
+metadataApi.searchGames(params: SearchGamesParams): Promise<EnrichedGame[]>
+
+// Crear juego desde metadatos
+metadataApi.createGameFromMetadata(data: CreateGameFromMetadataInput): Promise<Game>
+```
+
+## Flujo de Usuario
+
+1. El usuario navega a `/games/add`
+2. Ingresa un título de búsqueda (opcionalmente plataforma y año)
+3. Hace clic en "Buscar"
+4. El frontend llama a `metadataApi.searchGames()`
+5. El backend busca en IGDB, RAWG y TheGamesDB
+6. Los resultados se muestran en `SearchResults`
+7. El usuario selecciona un resultado
+8. Se abre `GamePreviewDialog` con los metadatos
+9. El usuario puede editar los campos según sea necesario
+10. Hace clic en "Guardar"
+11. El frontend llama a `metadataApi.createGameFromMetadata()`
+12. El juego se crea en la base de datos
+13. El usuario es redirigido a la página del juego
+
+## Configuración
+
+### Variables de Entorno
+
+**Backend:**
+
+```env
+# IGDB
+IGDB_CLIENT_ID=your_client_id
+IGDB_CLIENT_SECRET=your_client_secret
+
+# RAWG
+RAWG_API_KEY=your_api_key
+
+# TheGamesDB
+THEGAMESDB_API_KEY=your_api_key
+```
+
+**Frontend:**
+
+```env
+NEXT_PUBLIC_API_URL=http://localhost:3003/api
+```
+
+## Tests
+
+### Backend Tests
+
+- `tests/services/metadataService.spec.ts`: Tests del servicio de búsqueda
+- `tests/routes/metadata.spec.ts`: Tests de endpoints de metadatos
+- `tests/routes/games.spec.ts`: Tests de endpoints de juegos
+
+**Ejecutar tests:**
+
+```bash
+cd backend
+yarn test
+```
+
+### Frontend Tests
+
+- `src/components/games/__tests__/SearchForm.spec.ts`: Tests del formulario de búsqueda
+- `src/components/games/__tests__/SearchResults.spec.ts`: Tests de resultados de búsqueda
+- `src/components/games/__tests__/GamePreviewDialog.spec.ts`: Tests del diálogo de previsualización
+
+**Ejecutar tests:**
+
+```bash
+cd frontend
+yarn test
+```
+
+## Consideraciones de Diseño
+
+### Múltiples Fuentes
+
+El sistema busca en múltiples fuentes simultáneamente para maximizar la probabilidad de encontrar resultados. Cada resultado incluye:
+
+- La fuente de los datos (`source`)
+- Los IDs externos (`externalIds`) para referencia futura
+
+### Normalización de Datos
+
+Los datos de diferentes fuentes se normalizan a un formato común (`EnrichedGame`):
+
+- `name` y `title` se unifican
+- Las fechas se normalizan a formato ISO
+- Los géneros se mapean a strings
+- Las plataformas se normalizan
+
+### Validación
+
+- Los parámetros de búsqueda se validan con Zod
+- Los datos de creación de juego se validan antes de persistir
+- Los campos opcionales tienen valores por defecto apropiados
+
+### Error Handling
+
+- Errores de API externas no bloquean la búsqueda en otras fuentes
+- Errores de validación se devuelven con mensajes claros
+- Errores de red se manejan con reintentos y timeouts
+
+## Rendimiento
+
+- Las búsquedas en múltiples fuentes se ejecutan en paralelo
+- Los resultados se cachean por un período corto
+- Las imágenes se cargan de forma diferida (lazy loading)
+
+## Seguridad
+
+- Las claves de API se almacenan en variables de entorno
+- No se exponen credenciales en el frontend
+- Los inputs se validan y sanitizan
+- Se implementan rate limiting en las APIs externas
+
+## Roadmap Futuro
+
+- [ ] Soporte para más fuentes de metadatos
+- [ ] Búsqueda avanzada con filtros adicionales
+- [ ] Sugerencias de búsqueda mientras se escribe
+- [ ] Importación masiva desde listas externas
+- [ ] Sincronización automática de metadatos

+# Arquitectura: Nueva Pantalla de Búsqueda de Juegos
+
+## Resumen Ejecutivo
+
+Este documento describe la arquitectura para reemplazar el popup actual ([`GameDialog.tsx`](frontend/src/components/games/GameDialog.tsx)) por una página completa de búsqueda de juegos que permite buscar en múltiples proveedores externos (IGDB, RAWG, TheGamesDB) y seleccionar un resultado para guardar en la base de datos.
+
+## 1. Arquitectura del Backend
+
+### 1.1 Modificaciones al Endpoint Existente
+
+**Endpoint actual:** [`GET /api/metadata/search?q=query&platform=optional`](backend/src/routes/metadata.ts:22)
+
+**Problema actual:**
+
+- El endpoint usa [`enrichGame()`](backend/src/services/metadataService.ts:34) que solo devuelve el primer resultado encontrado
+- La respuesta es un array con un solo elemento o vacío
+
+**Solución propuesta:**
+Crear una nueva función en [`metadataService.ts`](backend/src/services/metadataService.ts) que busque en TODOS los proveedores y devuelva múltiples resultados.
+
+### 1.2 Nueva Función: `searchGames()`
+
+**Ubicación:** [`backend/src/services/metadataService.ts`](backend/src/services/metadataService.ts)
+
+```typescript
+export async function searchGames(opts: {
+  title: string;
+  platform?: string;
+  year?: number;
+}): Promise<EnrichedGame[]> {
+  // Buscar en IGDB, RAWG y TheGamesDB simultáneamente
+  // Devolver todos los resultados encontrados
+  // Aplicar deduplicación basada en nombre + plataforma + año
+}
+```
+
+**Lógica de búsqueda:**
+
+1. Ejecutar búsquedas en paralelo en los tres proveedores
+2. Normalizar todos los resultados usando la función [`normalize()`](backend/src/services/metadataService.ts:12) existente
+3. Aplicar deduplicación para evitar duplicados entre proveedores
+4. Ordenar resultados por relevancia (coincidencia exacta primero)
+5. Limitar resultados (ej: 20 resultados máximos por proveedor, 50 total)
+
+**Deduplicación:**
+
+- Agrupar por nombre normalizado (lowercase, sin caracteres especiales)
+- Si hay duplicados, priorizar: IGDB > RAWG > TheGamesDB
+- Mantener `externalIds` de todas las fuentes para cada resultado
+
+### 1.3 Modificación del Endpoint
+
+**Ubicación:** [`backend/src/routes/metadata.ts`](backend/src/routes/metadata.ts)
+
+**Cambios:**
+
+1. Actualizar el esquema de validación para incluir `year` como parámetro opcional
+2. Llamar a `searchGames()` en lugar de `enrichGame()`
+3. Devolver el array de resultados directamente
+
+```typescript
+const searchMetadataSchema = z.object({
+  q: z.string().min(1, 'El parámetro de búsqueda es requerido'),
+  platform: z.string().optional(),
+  year: z.coerce.number().int().min(1900).max(2100).optional(),
+});
+
+app.get('/metadata/search', async (request, reply) => {
+  const validated = searchMetadataSchema.parse(request.query);
+  const results = await metadataService.searchGames({
+    title: validated.q,
+    platform: validated.platform,
+    year: validated.year,
+  });
+  return reply.code(200).send(results);
+});
+```
+
+### 1.4 Estructura de Respuesta de la API
+
+```typescript
+// GET /api/metadata/search?q=mario&year=1990&platform=NES
+
+[
+  {
+    source: 'igdb',
+    externalIds: {
+      igdb: 1234,
+      rawg: 5678,
+      thegamesdb: 9012,
+    },
+    name: 'Super Mario Bros.',
+    title: 'Super Mario Bros.',
+    slug: 'super-mario-bros',
+    releaseDate: '1985-09-13T00:00:00.000Z',
+    genres: ['Platform'],
+    coverUrl: 'https://example.com/cover.jpg',
+    platforms: [
+      {
+        id: 18,
+        name: 'Nintendo Entertainment System (NES)',
+        abbreviation: 'NES',
+        slug: 'nes',
+      },
+    ],
+  },
+  // ... más resultados
+];
+```
+
+### 1.5 Nuevo Endpoint para Guardar Resultado
+
+**Endpoint:** `POST /api/games/from-metadata`
+
+**Propósito:** Crear un juego a partir de un resultado de búsqueda de metadatos.
+
+**Body:**
+
+```typescript
+{
+  "metadata": {
+    "source": "igdb",
+    "externalIds": { "igdb": 1234 },
+    "name": "Super Mario Bros.",
+    "slug": "super-mario-bros",
+    "releaseDate": "1985-09-13T00:00:00.000Z",
+    "genres": ["Platform"],
+    "coverUrl": "https://example.com/cover.jpg"
+  },
+  "overrides": {
+    "platform": "NES",
+    "year": 1985,
+    "description": "Descripción personalizada..."
+  }
+}
+```
+
+**Lógica:**
+
+1. Mapear metadatos a estructura de [`Game`](backend/prisma/schema.prisma:12)
+2. Aplicar overrides si se proporcionan
+3. Guardar en base de datos usando [`GamesController.createGame()`](backend/src/controllers/gamesController.ts:73)
+4. Devolver el juego creado
+

+
+## 2. Arquitectura del Frontend
+
+### 2.1 Nueva Ruta
+
+**Ruta:** `/games/add` o `/games/search`
+
+**Archivo:** [`frontend/src/app/games/add/page.tsx`](frontend/src/app/games/add/page.tsx)

+
+**Componentes shadcn/ui a usar:**
+
+- [`Card`](frontend/src/components/ui/card.tsx) para cada resultado
+- [`Button`](frontend/src/components/ui/button.tsx) para seleccionar
+
+**Props:**
+
+```typescript
+interface SearchResultsProps {
+  results: MetadataGame[];
+  onSelect: (result: MetadataGame) => void;
+  isLoading: boolean;
+}
+```
+
+#### 2.2.3 GamePreviewDialog Component
+
+**Ubicación:** [`frontend/src/components/games/GamePreviewDialog.tsx`](frontend/src/components/games/GamePreviewDialog.tsx)
+
+**Responsabilidades:**
+
+- Mostrar detalles completos del resultado seleccionado

+- [`Textarea`](frontend/src/components/ui/textarea.tsx) para descripción
+- [`Button`](frontend/src/components/ui/button.tsx) para acciones
+
+**Props:**

+  onOpenChange: (open: boolean) => void;
+  metadata: MetadataGame | null;
+  onSave: (metadata: MetadataGame, overrides: GameOverrides) => void;
+  isSaving: boolean;
+}
+```
+
+### 2.3 Flujo de Usuario
+
+```mermaid

+    E --> F[SearchResults muestra resultados]
+    F --> G[Usuario ve lista de juegos]
+    G --> H[Usuario hace clic en un resultado]
+    H --> I[GamePreviewDialog se abre]
+    I --> J[Usuario puede editar campos]
+    J --> K[Usuario hace clic en Guardar]
+    K --> L[LLAMADA API: POST /api/games/from-metadata]
+    L --> M{Éxito?}
+    M -->|Sí| N[Redirigir a /games o /games/id]
+    M -->|No| O[Mostrar error en dialog]

+
+### 2.6 Integración con Página de Juegos
+
+**Ubicación:** [`frontend/src/app/games/page.tsx`](frontend/src/app/games/page.tsx)
+
+**Cambio:**
+
+- Reemplazar el botón "Nuevo Juego" que abre [`GameDialog`](frontend/src/components/games/GameDialog.tsx) por un enlace a `/games/add`
+- Mantener [`GameDialog`](frontend/src/components/games/GameDialog.tsx) solo para edición de juegos existentes
+
+```typescript
+// Antes
+<Button onClick={handleCreate}>
+  <PlusIcon className="w-4 h-4 mr-2" />
+  Nuevo Juego
+</Button>
+
+// Después
+<Link href="/games/add">
+  <Button>
+    <PlusIcon className="w-4 h-4 mr-2" />
+    Añadir Juego
+  </Button>
+</Link>
+```

+8. ✅ Debe devolver array vacío cuando no hay resultados
+9. ✅ Debe manejar errores de API externas gracefully
+10. ✅ Debe limitar número de resultados
+
+**Ejemplo de test:**
+
+```typescript
+it('debe deduplicar resultados entre proveedores', async () => {
+  const mockIgdbResult = {
+    name: 'Super Mario Bros.',
+    source: 'igdb',
+    id: 1234,
+    // ... otros campos
+  };
+
+  const mockRawgResult = {
+    name: 'Super Mario Bros.',
+    source: 'rawg',
+    id: 5678,
+    // ... otros campos
+  };
+
+  vi.spyOn(igdb, 'searchGames').mockResolvedValue([mockIgdbResult]);
+  vi.spyOn(rawg, 'searchGames').mockResolvedValue([mockRawgResult]);
+
+  const results = await metadataService.searchGames({ title: 'mario' });
+
+  // Solo debería haber un resultado con ambos IDs externos
+  expect(results).toHaveLength(1);
+  expect(results[0].externalIds.igdb).toBe(1234);
+  expect(results[0].externalIds.rawg).toBe(5678);
+});
+```
+
+#### 3.2.2 Tests del Endpoint `/api/metadata/search`
+
+**Archivo:** [`backend/tests/routes/metadata.search.spec.ts`](backend/tests/routes/metadata.search.spec.ts)
+
+**Casos de prueba:**
+
+1. ✅ Debe devolver 200 con array de resultados
+2. ✅ Debe devolver 400 si falta parámetro `q`
+3. ✅ Debe devolver 400 si `year` no es válido
+4. ✅ Debe pasar parámetros a `searchGames()`
+5. ✅ Debe manejar errores del servicio
+
+#### 3.2.3 Tests del Endpoint `POST /api/games/from-metadata`
+
+**Archivo:** [`backend/tests/routes/games.from-metadata.spec.ts`](backend/tests/routes/games.from-metadata.spec.ts)
+
+**Casos de prueba:**
+
+1. ✅ Debe crear juego con metadatos de IGDB
+2. ✅ Debe crear juego con metadatos de RAWG
+3. ✅ Debe crear juego con metadatos de TheGamesDB
+4. ✅ Debe aplicar overrides cuando se proporcionan
+5. ✅ Debe guardar `externalIds` correctamente
+6. ✅ Debe devolver 400 si metadata es inválida
+7. ✅ Debe devolver 201 con juego creado
+
+### 3.3 Tests del Frontend
+
+#### 3.3.1 Tests Unitarios de Componentes
+
+**Archivo:** [`frontend/src/components/games/__tests__/SearchForm.test.tsx`](frontend/src/components/games/__tests__/SearchForm.test.tsx)
+
+**Casos de prueba:**
+
+1. ✅ Debe mostrar campos de formulario
+2. ✅ Debe validar que título es obligatorio
+3. ✅ Debe llamar `onSearch` con parámetros correctos
+4. ✅ Debe deshabilitar botón cuando `isLoading` es true
+
+**Archivo:** [`frontend/src/components/games/__tests__/SearchResults.test.tsx`](frontend/src/components/games/__tests__/SearchResults.test.tsx)
+
+**Casos de prueba:**
+
+1. ✅ Debe mostrar lista de resultados
+2. ✅ Debe mostrar mensaje cuando no hay resultados
+3. ✅ Debe llamar `onSelect` cuando se hace clic en resultado
+4. ✅ Debe mostrar estado de carga
+
+**Archivo:** [`frontend/src/components/games/__tests__/GamePreviewDialog.test.tsx`](frontend/src/components/games/__tests__/GamePreviewDialog.test.tsx)
+
+**Casos de prueba:**
+
+1. ✅ Debe mostrar metadatos del juego
+2. ✅ Debe permitir editar campos
+3. ✅ Debe llamar `onSave` con metadatos y overrides
+4. ✅ Debe cerrar cuando se cancela
+
+#### 3.3.2 Tests E2E
+
+**Archivo:** [`tests/e2e/game-search-flow.spec.ts`](tests/e2e/game-search-flow.spec.ts)
+
+**Casos de prueba:**
+
+1. ✅ Flujo completo: búsqueda → selección → guardado
+2. ✅ Búsqueda sin resultados
+3. ✅ Cancelar selección
+4. ✅ Editar campos antes de guardar
+5. ✅ Validación de errores
+
+**Ejemplo de test E2E:**
+
+```typescript
+test('flujo completo de búsqueda y guardado', async ({ page }) => {
+  await page.goto('/games/add');
+
+  // Ingresar búsqueda
+  await page.fill('input[name="title"]', 'Super Mario');
+  await page.click('button[type="submit"]');
+
+  // Esperar resultados
+  await page.waitForSelector('[data-testid="search-results"]');
+  const results = await page.locator('[data-testid="game-result"]').count();
+  expect(results).toBeGreaterThan(0);
+
+  // Seleccionar primer resultado
+  await page.click('[data-testid="game-result"]:first-child');
+
+  // Esperar dialog de preview
+  await page.waitForSelector('[data-testid="preview-dialog"]');
+
+  // Guardar
+  await page.click('[data-testid="save-button"]');
+
+  // Verificar redirección
+  await page.waitForURL(/\/games\/[a-z0-9]+$/);
+});
+```

+
+## 6. Consideraciones Adicionales
+
+### 6.1 Manejo de Errores
+
+**Backend:**
+
+- Capturar errores de APIs externas sin fallar completamente
+- Devolver resultados parciales si algún proveedor falla
+- Logging de errores para debugging
+
+**Frontend:**
+
+- Mostrar mensajes de error claros al usuario
+- Permitir reintentar búsqueda
+- Mostrar estado de carga durante búsquedas
+
+### 6.2 Performance
+
+**Backend:**
+
+- Usar `Promise.all()` para búsquedas paralelas
+- Implementar caching de resultados (opcional)
+- Limitar número de resultados por proveedor
+
+**Frontend:**
+
+- Implementar debounce en búsqueda
+- Lazy loading de imágenes de portada
+- Paginación de resultados si hay muchos
+
+### 6.3 Seguridad
+
+**Backend:**
+
+- Validar todos los parámetros de entrada
+- Sanitizar datos antes de guardar en BD
+- Rate limiting en endpoints de búsqueda
+
+**Frontend:**
+
+- Sanitizar HTML antes de mostrar
+- Validar en cliente y servidor
+
+### 6.4 Accesibilidad
+
+**Frontend:**
+
+- Labels en todos los campos de formulario
+- Focus management en dialogs
+- Keyboard navigation
+- ARIA labels donde sea necesario
+
+### 6.5 UX Considerations
+
+- Mostrar loading states claros
+- Feedback inmediato al usuario
+- Permitir cancelar búsqueda en progreso
+- Mostrar fuente de cada resultado (IGDB, RAWG, etc.)
+- Permitir ver más detalles antes de seleccionar
+- Confirmación antes de guardar
+
