protected $_compareItemFactory;
protected $_catalogProductCompareList;
public function __construct(
\Magento\Catalog\Model\Product\Compare\ItemFactory $compareItemFactory,
\Magento\Catalog\Model\Product\Compare\ListCompare $catalogProductCompareList,
\Magento\Catalog\Model\ProductFactory $productloader
) {
$this->_productloader = $productloader;
$this->_compareItemFactory = $compareItemFactory;
$this->_catalogProductCompareList = $catalogProductCompareList;
}
public function execute()
{
$productId = (int)$this->getRequest()->getParam('product');
$product=$this->_productloader->create()->load($productId);
$compareitem=$this->_compareItemFactory->create()->loadByProduct($product);
if($compareitem):
$this->_catalogProductCompareList->removeProduct($product);

As you can see magento 2 is using following code for removing the product from compare you can use this code too.
aria-label="<?php echo $block->escapeHtml(__('Remove Compare')); ?>"
data-post='<?php /* @escapeNotVerified */ echo $compareHelper->getPostDataRemove($_product); ?>'
role="button">
<span><?php /* @escapeNotVerified */ echo __('Remove Compare') ?></span>
</a>
Add product to compare
To perform the add product to compare collection task, following code should be able to get the desired result.
protected $_catalogProductCompareList;
public function __construct(
\Magento\Catalog\Model\Product\Compare\ListCompare $catalogProductCompareList,
\Magento\Catalog\Model\ProductFactory $productloader
) {
$this->_productloader = $productloader;
$this->_catalogProductCompareList = $catalogProductCompareList;
}
public function execute()
{
$productId = (int)$this->getRequest()->getParam('product');
$product=$this->_productloader->create()->load($productId);
$this->_catalogProductCompareList->addProduct($product);
}
A new file can be created to implement the above mentioned code and can be considered as a good technique but you can modify the existing file as well as per your requirements.
It is also a good practice to add your module and redirect it on your controllers, don’t try to edit the core file as it may get complicated.
