-# React + Vite
+## Amigos App (React + Vite + Express)
 
-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+Frontend (React/Vite) and backend (Express) are bundled into a single container for production. The backend serves the built frontend and exposes the API under `/api`.
 
-Currently, two official plugins are available:
+### Configuración del API en el frontend
 
-- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) for Fast Refresh
-- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+- Variable: `VITE_API_BASE`
+- Descripción: URL base del API para `fetch`. Si no se define, el frontend usa el mismo origen (recomendado detrás de Nginx).
+- Ejemplos:
+  - Mismo origen (proxy Nginx al contenedor): no definir `VITE_API_BASE`.
+  - API en dominio diferente: `VITE_API_BASE=https://api.ejemplo.com` (requiere CORS).
 
-## Expanding the ESLint configuration
+### Despliegue con Nginx (recomendado: mismo origen)
 
-If you are developing a production application, we recommend using TypeScript with type-aware lint rules enabled. Check out the [TS template](https://github.com/vitejs/vite/tree/main/packages/create-vite/template-react-ts) for information on how to integrate TypeScript and [`typescript-eslint`](https://typescript-eslint.io) in your project.
+Proxy del dominio al contenedor (sirve estáticos y `/api`):
+
+```
+server {
+  server_name amigos.nucleoriofrio.com;
+
+  # Opcional: gzip, TLS, etc.
+
+  location / {
+    proxy_pass http://amigos-app:3001; # nombre del servicio Docker
+    proxy_http_version 1.1;
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header X-Forwarded-Proto $scheme;
+  }
+}
+```
+
+Con esta configuración, no definas `VITE_API_BASE` para que el frontend use rutas relativas (`/api/...`).
+
+### Docker Compose
+
+El servicio expone el puerto 3001 dentro de la red de Docker. Asegúrate de que Nginx esté en la misma red (por ejemplo, `principal`) para alcanzar `amigos-app:3001`.
+
+### Diagnóstico rápido
+
+- 200 en `https://amigos.nucleoriofrio.com/health` indica que el backend está arriba.
+- Si el navegador muestra `ERR_CONNECTION_REFUSED`, revisa que el frontend no apunte a `http://localhost:3001` (usa `VITE_API_BASE` o mismo origen).
