Reindexing for one product in Magento 2

Hello Friends!
In this blog, we will learn how we can do reindexing for one product programmatically.

In Magento 2, when we create a new product or update an existing product, sometimes its inventory and prices don’t update on frontend. And we don’t want to execute the reindexing command from CLI after each change.

In that case, we can create an observer on ‘controller_action_catalog_product_save_entity_after‘ event, which is dispatched in /Magento/Catalog/Controller/Adminhtml/Product/Save Controller class in Magento 2.

And if we are creating or updating a product programmatically then we can add the following code statements in our code.

Here, I have done this in AdminProductSaveAfterObserver.php file inside app/code/Vendor/CustomModule/Observer/ directory.

                    }
                }
            }
        } catch (\Exception $e) {
            echo $e->getMessage();

}

Hope this will be helpful. Thanks 🙂
