# Installer på Hostinger

[Hostinger](https://hostinger.com) er en populær udbyder af shared hosting. Denne vejledning beskriver, hvordan du installerer BentoPDF på Hostingers shared hosting.

## Forudsætninger

- Hostinger-hostingplan med adgang til filhåndtering
- Node.js installeret lokalt til build

## Trin 1: Byg projektet

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

De byggede filer ligger i mappen `dist`.

## Trin 2: Upload til Hostinger

### Installation på rodomænet

1. Log ind på din Hostinger-konto
2. Gå til **File Manager** → **public_html**
3. **Slet** eventuelle eksisterende filer (tag backup, hvis nødvendigt)
4. **Upload** hele indholdet af din lokale `dist`-mappe til `public_html`

### Installation i en undermappe

Hvis du installerer i en undermappe (f.eks. `yourdomain.com/pdf-tools/`):

1. Byg med den korrekte base-URL:

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

2. Opret mappen i Hostinger:
   - Gå til **File Manager** → **public_html**
   - Opret en ny mappe: `pdf-tools`
3. Upload hele indholdet af `dist` til `public_html/pdf-tools/`

## Trin 3: Opret .htaccess-filen

Opret en `.htaccess`-fil i roden af din installationsmappe (`public_html` eller `public_html/pdf-tools/`):

::: warning Vigtigt
Ved installation i en undermappe skal du ændre `RewriteBase /` til `RewriteBase /pdf-tools/` (eller navnet på din mappe).

RewriteEngine On

# Remove trailing slash (except for language root directories)

# ============================================
# 5.1. LANGUAGE ROUTES
# ============================================
# Supported languages: de, es, zh, zh-TW, vi, it, id, tr, fr, pt
# English has no prefix - served from root

# English prefix redirects to root (for SEO consistency)
RewriteRule ^en/?$ / [R=301,L]
RewriteRule ^en/(.+)$ /$1 [R=301,L]

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

```

## Eksempel på .htaccess i en undermappe

For `yourdomain.com/pdf-tools/` skal du opdatere disse linjer:

```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
```

## Fejlfinding

### WASM-filer indlæses ikke

Sørg for, at MIME-typerne er sat korrekt i `.htaccess`:

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

### LibreOffice-værktøjer virker ikke

Sikkerhedsheaderne er afgørende for SharedArrayBuffer:

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

Hvis headerne ikke bliver anvendt, så kontakt Hostingers support for at aktivere `mod_headers`.

### 404-fejl ved genindlæsning af siden

Sørg for, at reglen for filtypen `.html` og sprogrutene er konfigureret korrekt. BentoPDF bruger statiske HTML-filer, ikke SPA-routing:

```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]
```

### Grænser for filupload

Hostinger kan have grænser for filstørrelse. Upload WASM-filer separat, hvis masseupload mislykkes.
