In this post I’ll share a standalone script that can be used to render a Magento 2 category page programmatically. This script can come in handy when debugging production issues on category pages (e.g. unexpected product set). For example, it can be executed under strace to review files opened, queries sent, and their corresponding results.

The Script

The script is as follows. Change $categoryId and $storeId as needed.

<?php

use Magento\Framework\App\Bootstrap;

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

$params = $_SERVER;

$bootstrap = Bootstrap::create(BP, $params);

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

$configLoader = $obj->get('Magento\Framework\ObjectManager\ConfigLoaderInterface');
$obj->configure($configLoader->load('frontend'));

$response = $obj->get('Magento\Framework\App\Response\Http');

$categoryId = '3';
$storeId = '1';

$obj->get('Magento\Store\Model\StoreManagerInterface')->setCurrentStore($storeId);

$controller = $obj->get('Magento\Catalog\Controller\Category\View');

$request = $obj->get('Magento\Framework\App\RequestInterface');

$request->setRouteName('catalog');
$request->setControllerName('category');
$request->setActionName('view');

$request->setParams([
    'id' => $categoryId
]);

$request->setDispatched(true);

$page = $controller->dispatch($request);

$page->renderResult($response);

echo $response->getContent();
