Magento 2 MSI Get Product's Inventory Location/Source on frontend

You can use \Magento\InventoryApi\Api\SourceItemRepositoryInterface class with \Magento\Framework\Api\SearchCriteriaBuilder to get source item data by source code and product SKU.

Here are the sample model class

    <?php

    namespace MageExpert\Testing\Model;

    class SourceItemModel

    {

       

        private $searchCriteriaBuilder;

        private $sourceItemRepository;

        public function __construct(

            ...

            \Magento\Framework\Api\SearchCriteriaBuilder $searchCriteriaBuilder,

            \Magento\InventoryApi\Api\SourceItemRepositoryInterface $sourceItemRepository

            ...

        ) {

            $this->searchCriteriaBuilder = $searchCriteriaBuilder;

            $this->sourceRepository = $sourceRepository;

        }

        public function getSourcesItems($souceCode, $sku)

        {

             $searchCriteria = $this->searchCriteriaBuilder

                ->addFilter('source_code', $souceCode)

                ->addFilter('sku', $sku)

                ->create();

            $sourceItemData = $this->sourceItemRepository->getList($searchCriteria);

            return $sourceItemData->getItems();

        }

    }

Now you can use getSourcesItems() function to get all source items by sources code

    $sourceCode = 'your_store_code';

    $sku = 'Product_1'

    $sourceItems = $this->getSourcesItems($sourceCode);

    foreach ($sourceItems as $sourceItem) {

        print_r($sourceItem->getData());

    }

OUTPUT:

    Array

    (

        [source_item_id] => 96

        [source_code] => your_store_code

        [sku] => Product_1

        [quantity] => 100.0000

        [status] => 1

    )
