I need to create a page where product collection from all categories or you can say from root level category (Default Category) generally it has id 2.

I need to make sure that the page is look like normal category where filter can be applied on product collection like brand, color and size etc and all toolbar related functionality sortby, pagination etc

I want to figure out the best approach how it can be done?

P.S: I don't need a solution like make new category and attach all category products to it.

Any help, experience and knowledge sharing would be appreciated.

    I used Amasty landing page module as a start and modified that. – Anthony May 28 at 8:43

I recently did the same sort of work. First you need to override Category block because you want the All products page just like category page. In order to get more understanding check getCurrentCategory function which set the current category to root category

Add block Path: app\code\Vendor\AllProducts\Block\Index\Index.php

<?php

namespace Vendor\AllProducts\Block\Index;


class Index extends \Magento\Framework\View\Element\Template {

    public function __construct(\Magento\Catalog\Block\Product\Context $context, array $data = []) {

        parent::__construct($context, $data);

    }


    protected function _prepareLayout()
    {
        return parent::_prepareLayout();
    }

}

Add Front controller, path should be like: app\code\Vendor\AllProducts\Controller\Index\Index.php

<?php

namespace Vendor\AllProducts\Controller\Index;

class Index extends \Magento\Framework\App\Action\Action
{
    private $context;
    private  $response;
    private  $redirect;
    /**
     * @var \Magento\Framework\UrlInterface
     */
    private $url;


    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\UrlInterface $url
    )
    {
        parent::__construct($context);
        $this->context = $context;
        $this->response = $context->getResponse();
        $this->redirect = $context->getRedirect();
        $this->url = $url;
        //return 
    }

    public function execute()
    {

        $this->_view->loadLayout();
        $this->_view->getLayout()->initMessages();
        $this->_view->renderLayout();
    }

    public function getResponse()
    {
        return $this->response;
    }
}

Add di.xml in your module for overriding guidance Path: app\code\Vendor\AllProducts\etc\di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="Magento\Catalog\Block\Category\View" type="Vendor\AllProducts\Block\Category\View" />
</config>

Override `catalog_category_view.xml` in your module. Path should be like: app\code\Vendor\AllProducts\view\frontend\layout\allproducts_index_index.xml
