How to Clear Magento 2 Cache – A Step by Step Guide

In the world of eCommerce, your website performance matters as much as your product quality. If you offer top-quality products but the website is lacking in speed or functionality, your store’s performance will be quite limited. The reason is competition. With so many eCommerce stores popping up, the concept of brand loyalty is eroding. Therefore, to beat the competition, you must always be one step ahead.

One way to improve your Magento store’s performance is through the ‘Clear Magento 2 Cache’ function. Cache Clean in Magento 2 ensures loading, formatting, and other issues are resolved, thereby enhancing the user experience. Clearing Magento cache is something every Magento store owner needs to learn.

You don’t need to have a technical background to clear the cache. Instead, all you need is a learning attitude and go through this guide with full attention. This step-by-step guide will help you understand how to effectively clear Magento 2 cache without asking your developer for it.

protected $cacheTypeList;

public function __construct(TypeListInterface $cacheTypeList,
Pool $cacheFrontendPool){
    $this->cacheTypeList = $cacheTypeList;
    $this->cacheFrontendPool = $cacheFrontendPool;

}

public function cacheFunction(Version $subject)
{
  $types = array('config','layout','block_html','collections','reflection','db_ddl','eav','config_integration','config_integration_api','full_page','translate','config_webservice');

    foreach ($types as $type) {
        $this->cacheTypeList->cleanType($type);
    }
    foreach ($this->cacheFrontendPool as $cacheFrontend) {
        $cacheFrontend->getBackend()->clean();
    }
}

How to Flush Magento 2 Cache?

Now go to Admin Panel> System> Cache Management. Over there you will see 2 big buttons on the top. The first one will Flush Magento Cache and the second one will Flush Cache Storage. Click on both to clear Magento Cache and Cache Storage for your website.

By clicking “Flush Magento Cache” all the default Magento Cache items that have Magento tag will be removed.

By clicking “Flush Cache Storage” all the items from Cache with Magento tag and without it will be removed.

Additional Cache Management:

Magento 2.0 has another method as well to Flush Catalog Images Cache and JavaScript/CSS Cache.

Navigate to Admin Panel> System> Cache Management and you will see the options at the bottom of the page as shown below.

The first option will remove the catalog images from all sections such as media/catalog/product/cache. The second option will remove the JavaScript copy and CSS files from the Cache of your Magento 2 store

Enable Magento 2 Full Page Cache

To improve your website performance and webpages loading speed, you can enable Full Page Cache option.

Magento 2 Clean Cache vs. Flush:

You can run both the commands to remove played out items from your website: clean and flush Magento 2 cache. However, it is important that you learn the difference:

Magento 2 Clean cache:

Flush Cache

Flushing a cache type purges the cache storage, which might affect other processes applications that are using the same storage. e.g. other websites. Flush cache types if you’ve already tried cleaning the cache and you’re still having issues that you cannot isolate.
