## 🚀 Quick Start

### 💡 Translate in 3 Ways

#### 1️⃣ **Using Helper Function**

```php
// Simple translation
echo translateText('Hello World', 'es');
// Output: Hola Mundo

// With auto-detection
echo translate('Bonjour', 'en');
// Output: Hello
```

#### 2️⃣ **Using Facade**

```php
use Subhashladumor1\Translate\Facades\Translate;

$translation = Translate::translate('Good morning', 'fr');
// Output: Bonjour
```

#### 3️⃣ **In Blade Templates**

```blade
<!-- Simple translation -->
<h1>@translate('Welcome to our site', 'es')</h1>

<!-- Block translation -->
@translateStart('de')
    This entire block will be translated to German.
    Multiple sentences are supported!
@translateEnd

<!-- Dynamic locale -->
<p>{{ translateText('Thank you', app()->getLocale()) }}</p>
```

## 📖 Complete Documentation

### 🎯 Basic Usage

#### **Translate Text**

```php
// Basic translation
$spanish = Translate::translate('Hello', 'es');

// Specify source language
$french = Translate::translate('Hello', 'fr', 'en');

// Auto-detect source
$result = Translate::translate('Hola', 'en', 'auto');
```

#### **Detect Language**

```php
$lang = Translate::detectLanguage('Bonjour le monde');
// Returns: 'fr'

// In Blade
<span>Language: @detectLang($userText)</span>
```

#### **Batch Translation**

```php
$texts = ['Hello', 'Goodbye', 'Thank you'];
$translations = Translate::translateBatch($texts, 'it');
// Returns: ['Ciao', 'Arrivederci', 'Grazie']

// Translate arrays
$data = [
    'title' => 'Welcome',
    'message' => 'Hello World',
    'items' => ['One', 'Two', 'Three']
];

$translated = app('translator')->translateArray($data, 'es');
```

# Output: Hola Mundo

# Specify source language
php artisan translate:string "Bonjour" en --source=fr
# Output: Hello
```

#### **2. Translate Files**

```

---

### 🎯 Advanced Features

#### **Middleware - Auto Locale Detection**

Register the middleware in your Laravel app:

```php
// In bootstrap/app.php (Laravel 11)
->withMiddleware(function (Middleware $middleware) {
    $middleware->alias([
        'detect.locale' => \Subhashladumor1\Translate\Http\Middleware\DetectLocale::class,
    ]);
})
```

Apply to routes:

```php
Route::middleware(['detect.locale'])->group(function () {
    Route::get('/', [HomeController::class, 'index']);
    Route::get('/products', [ProductController::class, 'index']);
});
```

**The middleware automatically detects locale from:**
1. URL query parameter (`?lang=es`)
2. User session
3. Authenticated user's language preference
4. Browser Accept-Language header
5. GeoIP (optional)

#### **Queue Integration**

For large translation jobs:

```php
use Illuminate\Support\Facades\Queue;

Queue::push(function() {
    $products = Product::all();
    
    foreach ($products as $product) {
        $translations = Translate::translateBatch([
            $product->name,
            $product->description
        ], 'es');
        
        // Save translations...
    }
});
```

Configure queue settings in `config/translate.php`:

```php
'queue' => [
    'enabled' => true,
    'connection' => 'redis',
    'queue' => 'translations',
],
```

---

### 📊 Analytics Dashboard

Access the beautiful analytics dashboard:

```
http://your-app.test/translate/dashboard
```

**Monitor:**
- 📈 Cache hit/miss rates
- ⚡ API latency per service
- 📝 Recent translation logs
- 🎯 Service performance comparison
- 💾 Storage efficiency

**Protect the dashboard** (recommended):

```php
// In routes/web.php or RouteServiceProvider
Route::middleware(['web', 'auth', 'can:view-analytics'])->group(function () {
    Route::get('/translate/dashboard', [\Subhashladumor1\Translate\Http\Controllers\DashboardController::class, 'index']);
});
```

---

### ⚙️ Configuration

#### **Service Configuration**

Edit `config/translate.php`:

```php
return [
    // Default translation service
    'default_service' => env('TRANSLATE_DEFAULT_SERVICE', 'libre'),
    
    // Fallback chain - tries services in order
    'fallback_chain' => ['libre', 'lingva', 'mymemory', 'google'],

|-----------|---------------|------------|-------------|
| Single Translation | ~150ms | ~1ms | **150x faster** |
| Batch (50 items) | ~3000ms | ~50ms | **60x faster** |
| File Translation | ~5000ms | ~100ms | **50x faster** |

### **Cache Hit Rates**

In production environments with proper caching:
- 📈 Average cache hit rate: **85-95%**
- ⚡ Average response time: **2-5ms**
- 💾 Storage overhead: **Minimal**

---

## 🛡️ Security

### **Best Practices**

```php
// ✅ GOOD - Sanitize input
$cleanText = strip_tags($userInput);
$translation = Translate::translate($cleanText, 'es');

// ❌ BAD - Direct user input
$translation = Translate::translate($_POST['text'], 'es');

// ✅ GOOD - Rate limiting
use Illuminate\Support\Facades\RateLimiter;

if (RateLimiter::tooManyAttempts('translate:'.$request->ip(), 60)) {
    abort(429);
}
```

### **Data Privacy**

- ⚠️ Text is sent to third-party APIs
- ✅ No data stored on our servers
- ✅ HTTPS encryption for all requests
- ✅ Use Argos for sensitive data (offline)
- ✅ Cache can be encrypted

**Read our [Security Policy](SECURITY.md) for more details.**
