Although Magento 2 well supports this need, store owners like you may be confused in how to do it quickly. The tutorial today is going to show 2 ways get product stock information in Magento 2**.

How to Get Product Stock Information in Magento 2

Use the class

Step 1: Declare the command to get product stock information

First, you will use a block class of the module Mageplaza_HelloWorld, then possibly inject the object of \Magento\CatalogInventory\Model\Stock\StockItemRepository class in the constructor of the module’s block class.

app/code/Mageplaza/HelloWorld/Block/HelloWorld.php

<?php
namespace Mageplaza\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{    
    protected $_stockItemRepository;
        
    public function __construct(
        \Magento\Backend\Block\Template\Context $context,        
        \Magento\CatalogInventory\Model\Stock\StockItemRepository $stockItemRepository,
        array $data = []
    )
    {
        $this->_stockItemRepository = $stockItemRepository;
        parent::__construct($context, $data);
    }
    
    public function getStockItem($productId)
    {
        return $this->_stockItemRepository->get($productId);
    }
}
?>

Step 2: Load product ID and SKU in template file

Next, please use the below script to load the product by id and sku in the template file.

$id = 123;
$_productStock = $block->getStockItem($id);
//print_r($_productStock->getData()); 
echo $_productStock->getQty(); echo '<br />';
echo $_productStock->getMinQty(); echo '<br />';
echo $_productStock->getMinSaleQty(); echo '<br />';
echo $_productStock->getMaxSaleQty(); echo '<br />';
echo $_productStock->getIsInStock(); echo '<br />';

That’s all you have to do to get the information on product stock. So easy, right?

Use Object Manager

Running the following code to retrieve product stock information in Magento 2:

$objectManager =  \Magento\Framework\App\ObjectManager::getInstance(); 
$stockItem = $objectManager->get('\Magento\CatalogInventory\Model\Stock\StockItemRepository');
$productId = 1; // YOUR PRODUCT ID
$productStock = $stockItem->get($productId);
var_dump($productStock->getData());

The bottom line
