The Rocket Java Script is an extension by Magefan that helps to defer JavaScript loading for Magento sites to speed up quickly. All JS code automatically moves to the bottom of the page (before body tag end). This speeds up page loading and increases the page load speed. Effectively improve loading time, attract more customers and your sale is on way to boost up!



  • Strongly defer JavaScript for your websites. Often, JavaScript (JS) is in between head and body. Furthermore, a website is loaded from top to bottom. If you have a lot of JavaScript code or a long string of code there, it takes very long before the web content appears because it needs to wait until all JavaScript codes are finished.The extension strongly optimizes customers’ experience by deferring JavaScript until it is needed on your website.
  • Easily configure from the admin panel. With a few clicks, you can get this extension work on your online store for better speed performance. The easy features with Magento basis save your time to get used to with it.
  • Reasonably developed on the Magento 2 Platform.  After thorough tests by Magefan Developers, the extension doesn't conflict with any functions on the Magento 2 Platform.
  • Sharply improve your site productivity.
