Reindexing programmatically in magento 2

Updated 28 March 2024

Reindexing programmatically in magento 2.

Reindex is the process of updating the transformed data as the data changes. E.g.: when updating a product price the data should be reindexed to be correctly displayed on the frontend.

In this article we will learn how to reindexing through code in magento 2.

You can write the below code in any class according to your need :

 * @var \Magento\Indexer\Model\IndexerFactory
protected $_indexerFactory;
 * @var \Magento\Indexer\Model\Indexer\CollectionFactory
protected $_indexerCollectionFactory;

public function __construct(
    \Magento\Indexer\Model\IndexerFactory $indexerFactory,
    \Magento\Indexer\Model\Indexer\CollectionFactory $indexerCollectionFactory
   $this->_indexerFactory = $indexerFactory;
   $this->_indexerCollectionFactory = $indexerCollectionFactory;

// you can call this function to do reindexing
public function reIndexing(){
   $indexerCollection = $this->_indexerCollectionFactory->create();
   $ids = $indexerCollection->getAllIds();
   foreach ($ids as $id) {
   $idx = $this->_indexerFactory->create()->load($id);
   $idx->reindexAll($id); // this reindexes all
   //$idx->reindexRow($id); // or you can use reindexRow according to your need

That’s all in this article, hope it will help you to call custom block and links inside footer. Try the above code and if you have any issue just comment below. 🙂
