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

You should use MagentoCatalogModelProductRepository or MagentoCatalogModelResourceModelProductCollection according your needs. You can use both methods to get product instances with all data.

Example 1 (Repository):

/**

 * @param MagentoCatalogModelProductRepository $productRepository

 * @param MagentoFrameworkApiSearchCriteriaInterface $criteria

 * @param MagentoFrameworkApiSearchFilterGroup $filterGroup

 * @param MagentoFrameworkApiFilterBuilder $filterBuilder

 * @param MagentoCatalogModelProductAttributeSourceStatus $productStatus

 * @param MagentoCatalogModelProductVisibility $productVisibility

 */

public function __construct(

    MagentoCatalogModelProductRepository $productRepository,

    MagentoFrameworkApiSearchCriteriaInterface $criteria,

    MagentoFrameworkApiSearchFilterGroup $filterGroup,

    MagentoFrameworkApiFilterBuilder $filterBuilder,

    MagentoCatalogModelProductAttributeSourceStatus $productStatus,

    MagentoCatalogModelProductVisibility $productVisibility

) {

    $this->productRepository = $productRepository;

    $this->searchCriteria = $criteria;

    $this->filterGroup = $filterGroup;

    $this->filterBuilder = $filterBuilder;

    $this->productStatus = $productStatus;

    $this->productVisibility = $productVisibility;



    $this->getProductData();

}



/**

 * @return MagentoCmsModelBlock|null

 * @throws MagentoFrameworkExceptionNoSuchEntityException

 */

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 MagentoCatalogModelResourceModelProductCollectionFactory $productCollectionFactory

 * @param MagentoCatalogModelProductAttributeSourceStatus $productStatus

 * @param MagentoCatalogModelProductVisibility $productVisibility

 * @throws MagentoFrameworkExceptionLocalizedException

 */

public function __construct(

    MagentoCatalogModelResourceModelProductCollectionFactory $productCollectionFactory,

    MagentoCatalogModelProductAttributeSourceStatus $productStatus,

    MagentoCatalogModelProductVisibility $productVisibility

) {

    $this->productCollectionFactory = $productCollectionFactory;

    $this->productStatus = $productStatus;

    $this->productVisibility = $productVisibility;

}



/**

 * @return MagentoFrameworkDataObject

 * @throws MagentoFrameworkExceptionLocalizedException

 */

public function getProducts()

{

    /** @var MagentoCatalogModelResourceModelProductCollection $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:

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

think your better shoot is catalogProductRepositoryV1

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.

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 MagentoCatalogApiProductRepositoryInterface $productRepository instead of it's implementation which is MagentoCatalogModelProductRepository $productRepository.
That way you you will have a space for future upgrade ability. Bottom line is use Service contracts as much as possible.
