Check if a category exists Shopware 6

Check if a category existsyour text

I have such code

 $categoryService = $this->container->get('category.repository');
    $newCategory = [
            'name' => 'Profi-Shop',
            'parentId' => null,
            'customFields' => [
        ],
    ];

    $categoryService->create([$newCategory], $context->getContext());

It is executed every time. How to execute it only if there is no such category

You need to check if your category exists prior creating it. If it does, then just skip creation step:

use Shopware\Core\Framework\DataAbstractionLayer\Search\Criteria;
use Shopware\Core\Framework\DataAbstractionLayer\Search\Filter\EqualsFilter;

$categoryService = $this->container->get('category.repository');
$newCategoryName = 'Profi-Shop';

// Search for the category first
$criteria = new Criteria();
$criteria->addFilter(new EqualsFilter('name', $newCategoryName));
$existingCategory = $categoryService->search($criteria, $context->getContext());

// Create it if there's no match found:
if ($existingCategory->getTotal() === 0) {
    $newCategory = [
        'name' => $newCategoryName,
        'parentId' => null,
        'customFields' => [],
    ];

    $categoryService->create([$newCategory], $context->getContext());
}
