It’s not a secret that every good vacation needs some planning. But this article is not about the place to go to, how to get the cheapest tickets or what stuff to take. This one is on how to prepare yourself mentally and what preparations to take before leaving your team or company for a vacation period and come back with minimum or no setbacks.

JavaScript bundling is an optimization technique you can use to reduce the number of server requests for JavaScript files. It is achieved by merging multiple JavaScript files together into one file to reduce the number of page requests. By default, Magento 2 allows excluding the particular JavaScript files from bundling by specifying the corresponding file in exclude node of the etc/view.xml file for a theme. However, sometimes it’s not enough.

Hello, I will be glad to share with you a few interesting tools that I use in QA work to make developer’s life a little bit more difficult.

Most likely, at least once you faced the issue when customer session does not work except an account page etc. And usually, it’s not obvious why. Is it a bug? No, actually that is the case when it’s not a bug, it’s kind of feature.

The Magento page cache library contains a simple PHP reverse proxy that enables page content caching. There are two types of distinguished content: private and public.

The “private” content is being served for each user separately and represents the personalized data of a customer. E.g. shopping cart, wishlist, customer addresses, notification messages. This data should not be cached on the server side, and should not be shown to more than one user. The private content is stored on the client’s side by Customer Data JS component (Magento_Customer/js/customer-data.js). However, this is a topic for another blog post. Today we will focus on the second content type – public content, or rather the cacheable content and its variations in terms of customer grouping.
