Patrones de arquitectura backend, diseño de API, optimización de base de datos y buenas prácticas del lado del servidor para Node.js, Express y rutas API de Next.js.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Patrones de Desarrollo Backend
Patrones de arquitectura backend y buenas prácticas para aplicaciones del lado del servidor escalables.
## Cuándo Activar
- Diseñar endpoints de API REST o GraphQL
- Implementar capas de repositorio, servicio o controlador
- Optimizar consultas de base de datos (N+1, indexación, connection pooling)
- Agregar caché (Redis, en memoria, headers de caché HTTP)
- Configurar trabajos en segundo plano o procesamiento asíncrono
- Estructurar manejo de errores y validación para APIs
- Construir middleware (auth, logging, rate limiting)
## Patrones de Diseño de API
### Estructura de API RESTful
```typescript
// PASS: URLs basadas en recursos
GET /api/markets # Listar recursos
GET /api/markets/:id # Obtener recurso individual
POST /api/markets # Crear recurso
PUT /api/markets/:id # Reemplazar recurso
PATCH /api/markets/:id # Actualizar recurso
DELETE /api/markets/:id # Eliminar recurso
// PASS: Parámetros de consulta para filtrado, ordenamiento, paginación
GET /api/markets?status=active&sort=volume&limit=20&offset=0
```
### Patrón Repository
```typescript
…
The line at the top of this page pins the label git:20260607.ac0f11c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
