How to Get Product Stock Quantity and Other Stock Information – Magento 2

In today’s tutorial, I am showing how to get the product stock quantity and information in Magento 2.

In this article, I will illustrate mainly two methods to get product stock information in Magento 2, and both methods are tested and confirmed it’s working.

#Method 1

This method will be using \Magento\CatalogInventory\Model\Stock\Item class to get the stock item in Magento 2

For the sake of example, I will use a helper class to get the stock details of a product.

class Data extends AbstractHelper
{
    public function __construct(
       ....
       \Magento\CatalogInventory\Model\Stock\Item $stockItem,
       ....

     ) {
       $this->_stockItem = $stockItem;

    }

    public function getStockDetails($productId) {
          $stockItemSingle = $this->_stockItem->load($productId, 'product_id');
          print $stockItemSingle->getQty();
    }
}

#Method 2

This method will be using \Magento\CatalogInventory\Api\StockStateInterface class to get the stock item in Magento 2

For the sake of example, I will use a helper class to get the stock details of a product.

class Data extends AbstractHelper
{
    protected $_stockStateInterface;
		public function __construct(
       ....
       \Magento\CatalogInventory\Api\StockStateInterface $stockStateInterface,
       ....

     ) {
       $this->_stockStateInterface = $stockStateInterface;

    }

    public function getStockDetails($productId) {
          print $this->_stockStateInterface->getStockQty($productId)
    }
}
