# Distribuzione su Hostinger

[Hostinger](https://hostinger.com) è un diffuso provider di hosting condiviso. Questa guida spiega come distribuire BentoPDF sull'hosting condiviso di Hostinger.

## Prerequisiti

- Piano di hosting Hostinger con accesso al file manager
- Node.js installato in locale per la build

## Passaggio 1: compila il progetto

```bash
git clone https://github.com/alam00000/bentopdf.git
cd bentopdf
npm install
npm run build
```

I file compilati saranno nella cartella `dist`.

## Passaggio 2: carica su Hostinger

### Distribuzione sul dominio principale

1. Accedi al tuo account Hostinger
2. Vai su **File Manager** → **public_html**
3. **Elimina** tutti i file esistenti (fai prima un backup se serve)
4. **Carica** tutto il contenuto della tua cartella locale `dist` in `public_html`

### Distribuzione in una sottodirectory

Se distribuisci in una sottodirectory (es. `yourdomain.com/pdf-tools/`):

1. Compila con l'URL di base corretto:

```bash
BASE_URL=/pdf-tools/ npm run build
```

2. Crea la cartella in Hostinger:
   - Vai su **File Manager** → **public_html**
   - Crea una nuova cartella: `pdf-tools`
3. Carica tutto il contenuto di `dist` in `public_html/pdf-tools/`

## Passaggio 3: crea il file .htaccess

Crea un file `.htaccess` nella radice della cartella di distribuzione (`public_html` o `public_html/pdf-tools/`):

::: warning Importante
Per la distribuzione in una sottodirectory, cambia `RewriteBase /` in `RewriteBase /pdf-tools/` (o il nome della tua cartella).

```apache
RewriteEngine On
RewriteBase /

## Esempio di .htaccess per sottodirectory

Per `yourdomain.com/pdf-tools/`, aggiorna queste righe:

```apache
RewriteBase /pdf-tools/

# ... (same content as above, but update paths) ...

# Language prefix root
RewriteCond %{DOCUMENT_ROOT}/pdf-tools/$1/index.html -f
RewriteRule ^(de|es|zh|zh-TW|vi|it|id|tr|fr|pt)/?$ /pdf-tools/$1/index.html [L]

# Language prefix with path
RewriteCond %{DOCUMENT_ROOT}/pdf-tools/$1/$2.html -f
RewriteRule ^(de|es|zh|zh-TW|vi|it|id|tr|fr|pt)/([^/]+)/?$ /pdf-tools/$1/$2.html [L]

# Root level .html extension
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.html -f
RewriteRule ^([^/]+)$ $1.html [L]

ErrorDocument 404 /pdf-tools/404.html
```

## Risoluzione dei problemi

### I file WASM non si caricano

Assicurati che i tipi MIME siano impostati correttamente in `.htaccess`:

```apache
AddType application/wasm .wasm
```

### Gli strumenti LibreOffice non funzionano

Gli header di sicurezza sono fondamentali per SharedArrayBuffer:

```apache
Header always set Cross-Origin-Opener-Policy "same-origin"
Header always set Cross-Origin-Embedder-Policy "require-corp"
```

Se gli header non vengono applicati, contatta il supporto di Hostinger per abilitare `mod_headers`.

### Errori 404 all'aggiornamento della pagina

Verifica che la regola per l'estensione `.html` e le route delle lingue siano configurate correttamente. BentoPDF usa file HTML statici, non il routing SPA:

```apache
# Language routes serve actual files from language directories
RewriteCond %{DOCUMENT_ROOT}/$1/$2.html -f
RewriteRule ^(de|es|zh|zh-TW|vi|it|id|tr|fr|pt)/([^/]+)/?$ /$1/$2.html [L]

# Root level pages
RewriteCond %{REQUEST_FILENAME}.html -f
RewriteRule ^([^/]+)$ $1.html [L]
```

### Limiti di caricamento dei file

Hostinger può avere limiti sulla dimensione dei file. Carica i file WASM separatamente se il caricamento in blocco fallisce.
