How to get Best Seller Product collection ?

Answer 1

Please try this code to get best seller product collections using objectManager.

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$productCollection = $objectManager->create('Magento\Reports\Model\ResourceModel\Report\Collection\Factory'); 
$collection = $productCollection->create('Magento\Sales\Model\ResourceModel\Report\Bestsellers\Collection'); 

$collection->setPeriod('year');
//$collection->setPeriod('month');
//$collection->setPeriod('day');

foreach ($collection as $item) {
    print_r($item->getData());
}

Answer 2

But if you want latest bestselling product collection for the day please use this code in block

public function getBestsellerProduct(){

$resourceCollection = $this->_resourceFactory->create('Magento\Sales\Model\ResourceModel\Report\Bestsellers\Collection');   
$resourceCollection->setPageSize(6);
$resourceCollection->setPeriod('day')->addStoreFilter(1)->getSelect()->order('period DESC');
return $resourceCollection;

}
