How to get a list of all products in Magento 2?

Question

How can I get a list of all available products in Magento 2?

Answer 1

You should use Magento\Catalog\Model\ProductRepository or Magento\Catalog\Model\ResourceModel\Product\Collection according your needs. You can use both methods to get product instances with all data.

Example 1 (Repository):

/**
 * @param \Magento\Catalog\Model\ProductRepository $productRepository
 * @param \Magento\Framework\Api\SearchCriteriaInterface $criteria
 * @param \Magento\Framework\Api\Search\FilterGroup $filterGroup
 * @param \Magento\Framework\Api\FilterBuilder $filterBuilder
 * @param \Magento\Catalog\Model\Product\Attribute\Source\Status $productStatus
 * @param \Magento\Catalog\Model\Product\Visibility $productVisibility
 */
public function __construct(
    \Magento\Catalog\Model\ProductRepository $productRepository,
    \Magento\Framework\Api\SearchCriteriaInterface $criteria,
    \Magento\Framework\Api\Search\FilterGroup $filterGroup,
    \Magento\Framework\Api\FilterBuilder $filterBuilder,
    \Magento\Catalog\Model\Product\Attribute\Source\Status $productStatus,
    \Magento\Catalog\Model\Product\Visibility $productVisibility
) {
    $this->productRepository = $productRepository;
    $this->searchCriteria = $criteria;
    $this->filterGroup = $filterGroup;
    $this->filterBuilder = $filterBuilder;
    $this->productStatus = $productStatus;
    $this->productVisibility = $productVisibility;

    $this->getProductData();
}

/**
 * @return \Magento\Cms\Model\Block|null
 * @throws \Magento\Framework\Exception\NoSuchEntityException
 */
protected function getProductData()
{

    $this->filterGroup->setFilters([
        $this->filterBuilder
            ->setField('status')
            ->setConditionType('in')
            ->setValue($this->productStatus->getVisibleStatusIds())
            ->create(),
        $this->filterBuilder
            ->setField('visibility')
            ->setConditionType('in')
            ->setValue($this->productVisibility->getVisibleInSiteIds())
            ->create(),
    ]);

    $this->searchCriteria->setFilterGroups([$this->filterGroup]);
    $products = $this->productRepository->getList($this->searchCriteria);
    $productItems = $products->getItems();

    return $productItems;
}

Result:

Example 2 (Collection):

/**
 * @param \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory
 * @param \Magento\Catalog\Model\Product\Attribute\Source\Status $productStatus
 * @param \Magento\Catalog\Model\Product\Visibility $productVisibility
 * @throws \Magento\Framework\Exception\LocalizedException
 */
public function __construct(
    \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory,
    \Magento\Catalog\Model\Product\Attribute\Source\Status $productStatus,
    \Magento\Catalog\Model\Product\Visibility $productVisibility
) {
    $this->productCollectionFactory = $productCollectionFactory;
    $this->productStatus = $productStatus;
    $this->productVisibility = $productVisibility;
}

/**
 * @return \Magento\Framework\DataObject[]
 * @throws \Magento\Framework\Exception\LocalizedException
 */
public function getProducts()
{
    /** @var \Magento\Catalog\Model\ResourceModel\Product\Collection $collection */
    $collection = $this->productCollectionFactory->create();
    $collection->joinAttribute('status', 'catalog_product/status', 'entity_id', null, 'inner');
    $collection->joinAttribute('visibility', 'catalog_product/visibility', 'entity_id', null, 'inner');
    $collection->addAttributeToFilter('status', ['in' => $this->productStatus->getVisibleStatusIds()])
        ->addAttributeToFilter('visibility', ['in' => $this->productVisibility->getVisibleInSiteIds()]);

    return $collection->getItems();
}

Result:

Answer 2

The most upvoted answer is working but I would like to mention that here by injecting a product repository implementation directly will cause the breach of service contract principle & that is something Magento wants developers to correct. You should inject \Magento\Catalog\Api\ProductRepositoryInterface $productRepository instead of it's implementation which is \Magento\Catalog\Model\ProductRepository $productRepository. That way you you will have a space for future upgrade ability. Bottom line is use Service contracts as much as possible.

Answer 3

Using a REST API call:

https://{host}/rest/V1/products/?searchCriteria=

Retrieves all products. "searchCriteria" is a required param, but can be left blank, as above.

Answer 4

You can do this through api request. Take a look at the default m2 api

think your better shoot is catalogProductRepositoryV1
