# Despliegue con Nginx
|
|
|
|
Aloja BentoPDF en tu propio servidor con Nginx.
|
|
|
|
## Requisitos previos
|
|
|
|
- Servidor Ubuntu/Debian
|
|
- Nginx instalado
|
|
- Certificado SSL (recomendado: Let's Encrypt)
|
|
|
|
## Paso 1: Compilar el proyecto
|
|
|
|
```bash
|
|
git clone https://github.com/alam00000/bentopdf.git
|
|
cd bentopdf
|
|
npm install
|
|
npm run build
|
|
```
|
|
|
|
Para personalizar la marca, define variables de entorno antes de compilar:
|
|
|
|
```bash
|
|
VITE_BRAND_NAME="AcmePDF" VITE_BRAND_LOGO="images/acme-logo.svg" npm run build
|
|
```
|
|
|
|
## Paso 2: Copiar los archivos
|
|
|
|
```bash
|
|
sudo mkdir -p /var/www/bentopdf
|
|
sudo cp -r dist/* /var/www/bentopdf/
|
|
sudo chown -R www-data:www-data /var/www/bentopdf
|
|
```
|
|
|
|
## Paso 3: Configuración de Nginx
|
|
|
|
Crea `/etc/nginx/sites-available/bentopdf`:
|
|
|
|
```nginx
|
|
server {
|
|
listen 80;
|
|
server_name your-domain.com;
|
|
return 301 https://$server_name$request_uri;
|
|
}
|
|
|
|
server {
|
|
listen 443 ssl http2;
|
|
server_name your-domain.com;
|
|
|
|
# SSL Configuration
|
|
ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
|
|
ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
|
|
|
|
root /var/www/bentopdf;
|
|
index index.html;
|
|
|
|
# Gzip compression
|
|
gzip on;
|
|
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/wasm;
|
|
gzip_min_length 1000;
|
|
|
|
# WASM MIME type
|
|
types {
|
|
application/wasm wasm;
|
|
}
|
|
|
|
# Required headers for SharedArrayBuffer (LibreOffice WASM)
|
|
# These must be on every response - especially HTML pages
|
|
add_header Cross-Origin-Embedder-Policy "require-corp" always;
|
|
add_header Cross-Origin-Opener-Policy "same-origin" always;
|
|
add_header Cross-Origin-Resource-Policy "cross-origin" always;
|
|
|
|
# Security headers
|
|
add_header X-Frame-Options "SAMEORIGIN" always;
|
|
add_header X-Content-Type-Options "nosniff" always;
|
|
add_header X-XSS-Protection "1; mode=block" always;
|
|
|
|
# Pre-compressed LibreOffice WASM binary
|
|
location ~* /libreoffice-wasm/soffice\.wasm\.gz$ {
|
|
gzip off;
|
|
types {} default_type application/wasm;
|
|
add_header Content-Encoding gzip;
|
|
add_header Cache-Control "public, immutable";
|
|
add_header Cross-Origin-Embedder-Policy "require-corp" always;
|
|
add_header Cross-Origin-Opener-Policy "same-origin" always;
|
|
}
|
|
|
|
# Pre-compressed LibreOffice WASM data
|
|
location ~* /libreoffice-wasm/soffice\.data\.gz$ {
|
|
gzip off;
|
|
types {} default_type application/octet-stream;
|
|
add_header Content-Encoding gzip;
|
|
add_header Cache-Control "public, immutable";
|
|
add_header Cross-Origin-Embedder-Policy "require-corp" always;
|
|
add_header Cross-Origin-Opener-Policy "same-origin" always;
|
|
}
|
|
|
|
# Cache static assets
|
|
location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff|woff2|wasm)$ {
|
|
expires 1y;
|
|
add_header Cache-Control "public, immutable";
|
|
add_header Cross-Origin-Embedder-Policy "require-corp" always;
|
|
add_header Cross-Origin-Opener-Policy "same-origin" always;
|
|
}
|
|
|
|
# SPA routing - serve index.html for all routes
|
|
location / {
|
|
try_files $uri $uri/ /index.html;
|
|
add_header Cross-Origin-Embedder-Policy "require-corp" always;
|
|
add_header Cross-Origin-Opener-Policy "same-origin" always;
|
|
}
|
|
}
|
|
```
|
|
|
|
## Paso 4: Activar el sitio
|
|
|
|
```bash
|
|
sudo ln -s /etc/nginx/sites-available/bentopdf /etc/nginx/sites-enabled/
|
|
sudo nginx -t
|
|
sudo systemctl reload nginx
|
|
```
|
|
|
|
## Paso 5: SSL con Let's Encrypt
|
|
|
|
```bash
|
|
sudo apt install certbot python3-certbot-nginx
|
|
sudo certbot --nginx -d your-domain.com
|
|
```
|
|
|
|
## Despliegue en un subdirectorio
|
|
|
|
Para alojarlo en `/pdf/`:
|
|
|
|
```nginx
|
|
location /pdf/ {
|
|
alias /var/www/bentopdf/;
|
|
try_files $uri $uri/ /pdf/index.html;
|
|
}
|
|
```
|
|
|
|
Compila con:
|
|
|
|
```bash
|
|
BASE_URL=/pdf/ npm run build
|
|
```
|
|
|
|
## Ajuste del rendimiento
|
|
|
|
Añade a `nginx.conf`:
|
|
|
|
```nginx
|
|
http {
|
|
# Enable sendfile
|
|
sendfile on;
|
|
tcp_nopush on;
|
|
tcp_nodelay on;
|
|
|
|
# Increase buffer sizes
|
|
client_max_body_size 100M;
|
|
|
|
# Worker connections
|
|
worker_connections 2048;
|
|
}
|
|
```
|
|
|
|
## Solución de problemas
|
|
|
|
### WASM no se carga
|
|
|
|
Asegúrate de que el tipo MIME esté definido:
|
|
|
|
```nginx
|
|
types {
|
|
application/wasm wasm;
|
|
}
|
|
```
|
|
|
|
### Firmar PDF o Rellenar formularios muestra un visor en blanco (error MIME de `.mjs`)
|
|
|
|
Si la consola del navegador muestra:
|
|
|
|
```
|
|
Failed to load module script: The server responded with a non-JavaScript
|
|
MIME type of "application/octet-stream". Strict MIME type checking is
|
|
enforced for module scripts per HTML spec.
|
|
```
|
|
|
|
...y la petición que falla termina en `.mjs`, a tu nginx le falta la asignación `.mjs → application/javascript`. El visor de PDF incluido (usado por Firmar PDF, Rellenar formularios y algunas otras herramientas) incorpora archivos de módulos ES con extensión `.mjs`, y el `mime.types` por defecto de nginx no los incluye.
|
|
|
|
Para solucionarlo, añade `mjs` a la línea `application/javascript` existente en `/etc/nginx/mime.types`:
|
|
|
|
```nginx
|
|
application/javascript js mjs;
|
|
```
|
|
|
|
> NO añadas una _segunda_ línea `application/javascript`: nginx analiza `mime.types` línea por línea y solo prevalece una asignación de tipo a extensión, así que en algunas versiones la segunda línea se ignora sin avisar. Edita la línea existente para añadir `mjs` junto a `js`.
|
|
|
|
O bien sobrescríbelo localmente dentro de tu bloque server (sin editar el archivo global):
|
|
|
|
```nginx
|
|
types {
|
|
application/javascript js mjs;
|
|
application/wasm wasm;
|
|
}
|
|
```
|
|
|
|
Recarga nginx después del cambio:
|
|
|
|
```bash
|
|
sudo nginx -t && sudo systemctl reload nginx
|
|
```
|
|
|
|
Para confirmarlo: en DevTools del navegador → pestaña Network, busca la petición `.mjs` que fallaba y revisa la cabecera de respuesta `Content-Type`. Ahora debería ser `application/javascript`, no `application/octet-stream`.
|
|
|
|
### La conversión de Word/ODT/Excel a PDF no funciona
|
|
|
|
LibreOffice WASM requiere `SharedArrayBuffer`, que necesita las cabeceras `Cross-Origin-Embedder-Policy` y `Cross-Origin-Opener-Policy`. También necesita un contexto seguro, así que `http://localhost` sirve para pruebas locales, pero `http://192.168.x.x` u otras IP de la red local normalmente requieren HTTPS. Ten en cuenta que las directivas `add_header` de nginx dentro de un bloque `location` **sobrescriben** las directivas `add_header` del nivel de servidor: no se combinan. Todo bloque `location` con sus propios `add_header` debe incluir las cabeceras COEP/COOP.
|
|
|
|
Verifica con:
|
|
|
|
```bash
|
|
curl -I https://your-domain.com/ | grep -i cross-origin
|
|
```
|
|
|
|
Si usas un proxy inverso delante de nginx, asegúrate de que conserve estas cabeceras.
|
|
|
|
### 502 Bad Gateway
|
|
|
|
Revisa los registros de errores de Nginx:
|
|
|
|
```bash
|
|
sudo tail -f /var/log/nginx/error.log
|
|
```
