Magento2 GraphQL for Newly Added Product

Question

I need to create GraphQL for newly added products.

Thanks in advance.

Answer 1

I have gotten the latest product based on the created_at field and get latest 10 products in GraphQl

app/code/Custom/NewlyProductGraphQl/etc/schema.graphqls

type Query {
        newlyCreatedProducts: [NewlyCreatedProducts] @resolver(class: "Custom\\NewlyProductGraphQl\\Model\\Resolver\\NewlyCreatedProducts")
    }
    type NewlyCreatedProducts {
        entity_id: Int
        name: String
        sku: String
    }

app/code/Custom/NewlyProductGraphQl/Model/Resolver/NewlyCreatedProducts.php

<?php

declare(strict_types=1);

namespace Custom\NewlyProductGraphQl\Model\Resolver;

use Magento\Catalog\Model\Product\Visibility;
use Magento\Catalog\Model\ResourceModel\Product\CollectionFactory;
use Magento\Framework\GraphQl\Config\Element\Field;
use Magento\Framework\GraphQl\Query\Resolver\Value;
use Magento\Framework\GraphQl\Query\ResolverInterface;
use Magento\Framework\GraphQl\Schema\Type\ResolveInfo;
use Magento\Framework\GraphQl\Query\Resolver\ValueFactory;

/**

        $this->valueFactory = $valueFactory;
    }

    public function resolve(
        Field       $field,

        ResolveInfo $info,
        array       $value = null,
        array       $args = null
    ) {
        $data = $this->getNewlyProductCollection();
        $result = function () use ($data) {
            return !empty($data) ? $data : [];
        };
        return $this->valueFactory->create($result);
    }

    /**
     * @return array
     */
    public function getNewlyProductCollection(): array
    {
        $productData = [];
        $collection = $this->productCollectionFactory->create();
        $collection->setVisibility($this->catalogProductVisibility->getVisibleInCatalogIds());
        $collection = $collection->addStoreFilter()
            ->addAttributeToSelect('*')
            ->addAttributeToSort('created_at', 'desc')
            ->setPageSize(10)
            ->setCurPage(1);
        foreach ($collection as $product) {
            array_push($productData, $product->getData());
        }
        return $productData ?: [];
    }
}

Query:

query{
  newlyCreatedProducts{
    entity_id
    name
    sku
  }
}

Thanks.
