Installation

1. Install via Composer:

composer require mmnijas/deepseek

1. Add your DeepSeek API key to .env:

DEEPSEEK_API_KEY=your-api-key-here

1. (Optional) Publish config file:

php artisan vendor:publish --tag=deepseek-config

Configuration

After publishing the config file (config/deepseek.php), you can customize:

return [
    'api_key' => env('DEEPSEEK_API_KEY'),    // Your API key
    'base_uri' => 'https://api.deepseek.com/v1', // API endpoint
    'model' => 'deepseek-chat',              // Default model
    'timeout' => 30,                         // Request timeout in seconds
];

Basic Usage

1. Using the Facade

use Mmnijas\DeepSeek\Facades\DeepSeek;

$response = DeepSeek::chat([
    ['role' => 'user', 'content' => 'Hello, DeepSeek!']
]);

// Get the assistant's reply
echo $response['choices'][0]['message']['content'];

2. In a Controller

use Mmnijas\DeepSeek\Facades\DeepSeek;
use Illuminate\Http\Request;

class ChatController extends Controller
{
    public function handle(Request $request)
    {
        $messages = [
            ['role' => 'user', 'content' => $request->input('message')]
        ];

        $response = DeepSeek::chat($messages);

        return response()->json([
            'reply' => $response['choices'][0]['message']['content']
        ]);
    }
}

3. Blade View Example

<form action="/chat" method="POST">
    @csrf
    <input type="text" name="message" required>
    <button type="submit">Ask DeepSeek</button>
</form>

@isset($response)
<div class="response">
    {{ $response['choices'][0]['message']['content'] }}
</div>
@endisset

4. Artisan Command

Create a command:

php artisan make:command AskDeepSeek

Implement:

use Mmnijas\DeepSeek\Facades\DeepSeek;

class AskDeepSeek extends Command
{
    protected $signature = 'ask:deepseek {question}';

    public function handle()
    {
        $response = DeepSeek::chat([
            ['role' => 'user', 'content' => $this->argument('question')]
        ]);

        $this->info($response['choices'][0]['message']['content']);
    }
}

Usage:

php artisan ask:deepseek "What is Laravel?"

Advanced Usage

Custom Parameters

$response = DeepSeek::chat(
    messages: [
        ['role' => 'user', 'content' => 'Explain quantum computing in simple terms']
    ],
    params: [
        'temperature' => 0.7,
        'max_tokens' => 500,
        'top_p' => 1.0,
    ]
);

Multiple Messages

$messages = [
    ['role' => 'system', 'content' => 'You are a helpful assistant'],
    ['role' => 'user', 'content' => 'Who won the world series in 2020?'],
    ['role' => 'assistant', 'content' => 'The Los Angeles Dodgers won the World Series in 2020.'],
    ['role' => 'user', 'content' => 'Where was it played?']
];

$response = DeepSeek::chat($messages);

Error Handling

try {
    $response = DeepSeek::chat([...]);
} catch (\Exception $e) {
    // Handle API errors
    logger()->error('DeepSeek API Error: ' . $e->getMessage());
    return response()->json(['error' => 'Service unavailable'], 503);
}

Rate Limiting

The DeepSeek API has rate limits. Implement Laravel's rate limiter in AppServiceProvider:

use Illuminate\Cache\RateLimiting\Limit;
use Illuminate\Support\Facades\RateLimiter;

RateLimiter::for('deepseek', function ($job) {
    return Limit::perMinute(60); // Adjust based on your API plan
});

Testing

Add to your test case:

public function test_deepseek_integration()
{
    Http::fake([
        'api.deepseek.com/v1/chat/completions' => Http::response([
            'choices' => [
                ['message' => ['content' => 'Mocked response']]
            ]
        ], 200)
    ]);

    $response = DeepSeek::chat([
        ['role' => 'user', 'content' => 'Test message']
    ]);

    $this->assertEquals('Mocked response', $response['choices'][0]['message']['content']);
}

Security

Always:

• 🔑 Keep your API key secret
• 🛡 Validate user input
• ⏱ Implement rate limiting
• 📝 Follow DeepSeek's API guidelines

Common Issues

Missing API Key

Error: "DeepSeek API key not configured"
Solution: Verify .env contains DEEPSEEK_API_KEY

Network Errors

Error: "Could not connect to DeepSeek API"
Solution:

1. Check internet connection
2. Verify API endpoint in config
3. Review firewall settings

Invalid Response Format

Error: "Undefined index choices"
Solution:

// Check for successful response first
if (isset($response['choices'])) {
    // Process response
}
