🚀 Usage

Using the Service (Backend Logic)

Resolve the AiChatService anywhere in your application — controllers, jobs, commands, etc. — to handle custom logic:

use Illuminate\Support\Str;
use Illuminate\Http\Request;
use Mahbub\LaravelAiChatbot\Services\AiChatService;
use Mahbub\LaravelAiChatbot\Models\ChatSession;

class ChatController extends Controller
{
    protected $chatService;

    public function __construct(AiChatService $chatService)
    {
        $this->chatService = $chatService;
    }

    public function __invoke(Request $request)
    {
        // 1. Get or create a chat session for the user
        $session = ChatSession::firstOrCreate([
            'session_id' => $request->get('session_id') ?? Str::uuid(),
        ]);

        // 2. Send the message and get the AI response (history saved automatically)
        $aiResponse = $this->chatService->sendMessage($session, $request->get('message'));

        return response()->json([
            'session_id' => $session->session_id,
            'response'   => $aiResponse,
        ]);
    }
}
