Magento2 get product data by loading product id in root directory

 Create test.php in magento root directory

<?php

echo '<pre>';

require __DIR__ . '/app/bootstrap.php';

$bootstrap = \Magento\Framework\App\Bootstrap::create(BP, $_SERVER);

/** @var \Magento\Framework\App\Http $app */

$obj = $bootstrap->getObjectManager();

$state = $obj->get('Magento\Framework\App\State');

$state->setAreaCode('frontend');

/** @var \Magento\Framework\App\Http $app */

$app = $bootstrap->createApplication('TestApp');

$bootstrap->run($app);

And next create TestApp.php

<?php

class TestApp extends \Magento\Framework\App\Http implements \Magento\Framework\AppInterface {

 public function launch() {

       echo '<pre>';

        $objectManager = \Magento\Framework\App\ObjectManager::getInstance();

        $product = $objectManager->get('Magento\Catalog\Model\Product')->load(2047);

        var_dump($product->getName());

        return $this->_response;

//        $collection = $this->_objectManager->create('\Magento\Catalog\Model\ResourceModel\Product\Collection');

//        $collection->addAttributeToSelect('*');

        print_r($data);

    }

public function catchException(\Magento\Framework\App\Bootstrap $bootstrap, \Exception $exception) {

        return false;

    }

}
