Non-cacheable blocks in Magento 2 play a crucial role in shaping the caching behavior of web pages. Since these blocks are not cached, they are re-rendered on each request, ensuring that the latest information is always displayed to the user. Consequently, they are particularly useful for elements like shopping cart summaries, customer-specific content, or any other data that needs to be updated frequently.

In this guide, we’ll explore 2 effective methods to create a non-cacheable block in Magento 2. They consist of using a custom block class and any existing block. This will ensure that your dynamic content stays up-to-date for your customers. Let’s get started!

How to Create A Non-cacheable Block in Magento 2

In Magento 2, you can create a non-cacheable block by extending the \Magento\Framework\View\Element\Template class and setting the cacheable attribute to false.

Here’s a basic 2 methods to achieve this:

Method 1: Use Custom Block Class

1 . Create your custom block class, which will extend the \Magento\Framework\View\Element\Template class.

For example, name the custom block class NonCacheableBlock

<?php
namespace Vendor\Module\Block;

class NonCacheableBlock extends \Magento\Framework\View\Element\Template
{
    /**
     * @return bool
     */
    protected function _isScopePrivate()
    {
        return true;
    }

    /**
     * @return $this
     */
    protected function _prepareLayout()
    {
        $this->addData([
            'cache_lifetime' => false,
            'cache_tags' => [],
            'cache_key' => $this->getCacheKey()
        ]);
        return parent::_prepareLayout();
    }
}

1. Create a template file in app/code/Vendor/Module/view/frontend/templates/noncacheableblock.phtml ```

This is a non-cacheable block

3. Create layout XML file located in ``app/code/Vendor/Module/view/frontend/layout/default.xml``

<?xml version=”1.0”?>

4. Clear the cache after adding the block. Then check the content of the page

### Method 2: Use Any Existing Block

You can apply ``cacheable=”false” `` attribute directly in your layout XML file to disable cache for the block.

Run the code below :

<?xml version=”1.0”?>

``` In conclusion Creating non-cacheable blocks in Magento 2 allows you to display dynamic content that requires real-time updates without being affected by the caching mechanism. By following the steps outlined in this guide, you can make sure that your e-commerce website delivers a personalized and seamless experience for your customers.
