Minifying Javascript, HTML and CSS in Magento 2

MINIFYING JAVASCRIPT, HTML AND CSS IN MAGENTO 2

Minifying Javascript, HTML and CSS is a great way to speed up your Magento 2 store. Some people might mistake it for compression. However, it is a completely different concept. Compression is a way to reduce the file size for the ease of transferring data between a client and a server. Various compression algorithms are used to compress and decompress files. In the case of minification, the browser is able to identify the code without any extra steps. So, what is minification? And how can you enable it on your Magento 2 store? Read below to learn everything you need to know about minifying code in Magento 2. 

Definition of Minification

Minification is a process by which a code can be optimized so that extra or unnecessary elements can be removed from the code while keeping the functionality intact. Even if you minify your code browser will still be able to recognize it and execute it as well. You can modify any code such as HTML, CSS, Javascript etc.

Magento 2 offers options to minify Javascript, HTML, and CSS out of the box. So you can turn it on or off directly from your admin panel. Minification essentially removes whitespaces, comments, newline characters etc. from the code so that the code becomes very short. It is not feasible to minify your code in the start because it becomes highly complicated to debug such code. Hence, Minification should always be performed as the last step.  Let us learn some advantages of minifying Javascript and CSS in Magento 2.

  • Your webpage will load much faster if your javascript, CSS and HTML files are minified.
