# Desplegar en AWS S3 + CloudFront
|
|
|
|
Aloja BentoPDF en AWS para obtener el máximo control y escalabilidad.
|
|
|
|
## Arquitectura
|
|
|
|
```
|
|
User → CloudFront (CDN) → S3 (Static Files)
|
|
```
|
|
|
|
## Paso 1: Crear el bucket de S3
|
|
|
|
```bash
|
|
# Create bucket
|
|
aws s3 mb s3://your-bentopdf-bucket --region us-east-1
|
|
|
|
# Enable static website hosting
|
|
aws s3 website s3://your-bentopdf-bucket \
|
|
--index-document index.html \
|
|
--error-document index.html
|
|
```
|
|
|
|
## Paso 2: Compilar y subir
|
|
|
|
```bash
|
|
# Build the project (optionally with custom branding)
|
|
# VITE_BRAND_NAME="AcmePDF" VITE_BRAND_LOGO="images/acme-logo.svg" npm run build
|
|
npm run build
|
|
|
|
# Sync to S3
|
|
aws s3 sync dist/ s3://your-bentopdf-bucket \
|
|
--delete \
|
|
--cache-control "max-age=31536000"
|
|
|
|
# Set correct MIME types for WASM
|
|
aws s3 cp s3://your-bentopdf-bucket/ s3://your-bentopdf-bucket/ \
|
|
--recursive \
|
|
--exclude "*" \
|
|
--include "*.wasm" \
|
|
--content-type "application/wasm" \
|
|
--metadata-directive REPLACE
|
|
|
|
# Set correct MIME type for ES module files (.mjs)
|
|
# S3 defaults .mjs to application/octet-stream, which browsers refuse to
|
|
# execute as ES modules. The bundled PDF viewer (Sign PDF, Form Filler)
|
|
# ships ES modules with .mjs extensions and will fail without this step.
|
|
aws s3 cp s3://your-bentopdf-bucket/ s3://your-bentopdf-bucket/ \
|
|
--recursive \
|
|
--exclude "*" \
|
|
--include "*.mjs" \
|
|
--content-type "application/javascript" \
|
|
--metadata-directive REPLACE
|
|
```
|
|
|
|
## Paso 3: Crear la distribución de CloudFront
|
|
|
|
```bash
|
|
aws cloudfront create-distribution \
|
|
--origin-domain-name your-bentopdf-bucket.s3.amazonaws.com \
|
|
--default-root-object index.html
|
|
```
|
|
|
|
O usa la consola de AWS:
|
|
|
|
1. Ve a CloudFront → Create distribution
|
|
2. Origin domain: selecciona tu bucket de S3
|
|
3. Activa "Origin Access Control"
|
|
4. Default root object: `index.html`
|
|
5. Crea la distribución
|
|
|
|
## Paso 3b: Política de cabeceras de respuesta (necesaria para LibreOffice WASM)
|
|
|
|
Las conversiones basadas en LibreOffice (Word, Excel, PowerPoint a PDF) requieren `SharedArrayBuffer`, que necesita cabeceras de respuesta específicas. Crea una Response Headers Policy de CloudFront:
|
|
|
|
1. Ve a CloudFront → Policies → Response headers
|
|
2. Crea una política personalizada con estas cabeceras:
|
|
|
|
| Cabecera | Valor |
|
|
| ------------------------------ | -------------- |
|
|
| `Cross-Origin-Embedder-Policy` | `require-corp` |
|
|
| `Cross-Origin-Opener-Policy` | `same-origin` |
|
|
| `Cross-Origin-Resource-Policy` | `cross-origin` |
|
|
|
|
3. Asocia la política al comportamiento de caché predeterminado de tu distribución
|
|
|
|
O mediante la CLI:
|
|
|
|
```bash
|
|
aws cloudfront create-response-headers-policy \
|
|
--response-headers-policy-config '{
|
|
"Name": "BentoPDF-COEP-COOP",
|
|
"CustomHeadersConfig": {
|
|
"Quantity": 3,
|
|
"Items": [
|
|
{"Header": "Cross-Origin-Embedder-Policy", "Value": "require-corp", "Override": true},
|
|
{"Header": "Cross-Origin-Opener-Policy", "Value": "same-origin", "Override": true},
|
|
{"Header": "Cross-Origin-Resource-Policy", "Value": "cross-origin", "Override": true}
|
|
]
|
|
}
|
|
}'
|
|
```
|
|
|
|
## Paso 3c: Metadatos de S3 para los archivos WASM precomprimidos
|
|
|
|
Los archivos WASM de LibreOffice están precomprimidos (`.wasm.gz`, `.data.gz`). Define el Content-Type y el Content-Encoding correctos para que los navegadores los descompriman:
|
|
|
|
```bash
|
|
# Set correct headers for soffice.wasm.gz
|
|
aws s3 cp s3://your-bentopdf-bucket/libreoffice-wasm/soffice.wasm.gz \
|
|
s3://your-bentopdf-bucket/libreoffice-wasm/soffice.wasm.gz \
|
|
--content-type "application/wasm" \
|
|
--content-encoding "gzip" \
|
|
--metadata-directive REPLACE
|
|
|
|
# Set correct headers for soffice.data.gz
|
|
aws s3 cp s3://your-bentopdf-bucket/libreoffice-wasm/soffice.data.gz \
|
|
s3://your-bentopdf-bucket/libreoffice-wasm/soffice.data.gz \
|
|
--content-type "application/octet-stream" \
|
|
--content-encoding "gzip" \
|
|
--metadata-directive REPLACE
|
|
```
|
|
|
|
::: warning Importante
|
|
Sin la política de cabeceras de respuesta, `SharedArrayBuffer` no está disponible y las conversiones de LibreOffice WASM se quedarán colgadas en torno al 55 %. Sin el Content-Encoding correcto en los archivos `.gz`, el navegador recibe bytes gzip sin procesar y la compilación de WASM falla.
|
|
:::
|
|
|
|
## Paso 4: Política del bucket de S3
|
|
|
|
Permite que CloudFront acceda al bucket:
|
|
|
|
```json
|
|
{
|
|
"Version": "2012-10-17",
|
|
"Statement": [
|
|
{
|
|
"Sid": "AllowCloudFrontAccess",
|
|
"Effect": "Allow",
|
|
"Principal": {
|
|
"Service": "cloudfront.amazonaws.com"
|
|
},
|
|
"Action": "s3:GetObject",
|
|
"Resource": "arn:aws:s3:::your-bentopdf-bucket/*",
|
|
"Condition": {
|
|
"StringEquals": {
|
|
"AWS:SourceArn": "arn:aws:cloudfront::ACCOUNT_ID:distribution/DISTRIBUTION_ID"
|
|
}
|
|
}
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
## Paso 5: Páginas de error personalizadas
|
|
|
|
Configura el 404 para que devuelva `index.html` y funcione el enrutamiento SPA:
|
|
|
|
1. CloudFront → Error pages
|
|
2. Crea una respuesta de error personalizada:
|
|
- HTTP error code: 404
|
|
- Response page path: `/index.html`
|
|
- HTTP response code: 200
|
|
|
|
## Estimación de costes
|
|
|
|
| Recurso | Coste estimado |
|
|
| ---------------------------------- | -------------- |
|
|
| Almacenamiento S3 (~500MB) | ~$0.01/mes |
|
|
| CloudFront (1TB de transferencia) | ~$85/mes |
|
|
| CloudFront (10GB de transferencia) | ~$0.85/mes |
|
|
|
|
::: tip
|
|
Usa S3 Intelligent Tiering para optimizar costes en archivos a los que se accede con poca frecuencia.
