How to Set Up a CDN in Magento 2

A Content Delivery Network, or CDN, reduces the load on your server by hosting static cached content on globally distributed servers. It provides a local Point of Presence that lowers data transfers and response times.

Let’s learn how to set up a CDN in Magento 2 below to offer your customers a better user experience. We’re using Magento 2.4.1 for this tutorial.

Recommendation

Before we begin, we recommend you test your website performance by using Google Page Speed or Pingdom Tools. After setting up the CDN to work with your Magento store, you can test page load time again and do a before and after comparison.

This guide assumes you’ve already configured a CDN to work with your server. We’ll be covering how to install a CDN in Magento 2.

    Base URL for User Media Files: Add the URL of the JavaScript files on the CDN.
    Note that the URLs will depend on if you’ve installed your Magento 2 store with or without pub in the path. You can leave these fields empty or start the URL path with the {{unsecure_base_url}} placeholder.

How to Check if CDN is Enabled in Magento 2

Follow these steps to check if the CDN is working:

  1. Clear browser cache.
  2. Open your website and right-click on the page.
    View Page Source on front end
    Right-click on any frontend page and then click on View Page Source
  3. Click on View Page Source, and a new window showing your site’s HTML will pop up.
  4. Browse the HTML and search for static assets like .css, .png, and .js. You’ve integrated CDN successfully if you see a CDN URL that you set up while integrating CDN to your Magento store.

Note: If the product images and styles fail to load on the frontend, check for a typo in the URLs of static media and user media files.
