Working without troubles, I already installed this module on few Magento versions 2.3-2.4
It reduces the initial loading time and delivers a web page to customers faster!
We also provide a script that allows you to compile a list of used JS, so you know what to optimize with the deferred loading.
Yes, you can. All our modules can be installed via the composer. Once you purchase the extension, you receive keys to the private Magefan composer repository and find the composer installation commands available in the "My Downloads" section.
