One of Magento 2 goals is to enable performance for all and scalability for Enterprise customers. Page Cache plays an important role in Magento 2. Starting from Magento 2.0.0 release Page Cache functionality (it is also known as Magento Full Page Cache) is available for Magento 2 Community Edition.
As we all know, the page’s HTML <head> section contains different meta tags, CSS and JS files definition, pieces of JS code etc. As a rule, we don’t need any complex logic to add some proper content there. However, let’s imagine the situation when we need to insert some element that depends on the system configuration or so into the head section.
We remember the time when we were waiting for Magento 2 release and were so excited when it happened. Magento team put a lot of effort into that release and delighted us with new improvements. Since that time, many store owners come curious to know if they should migrate the store from Magento 1 to Magento 2 and if so – when it should happen.
Have you ever edited a CMS page? Perhaps you’ve inserted a custom image or just added a link to another page of your store. What did you do for that? We assume that you simply copy-pasted the link from your browser and inserted it to the CMS page directly. Then, you have edited one more CMS page or block in the same way. It looks like a good solution. However, imagine that one day you will need a solution for changing, let’s say, a domain name of your store. You will need to fix the old domain name in each of the edited CMS pages and blocks to prevent redirect to it. This is not good approach and, to improve that process, we should use directives.
We are going to talk about event system approach in development. The event is a very flexible way to extend application logic. This approach is actual in both Magento 1 and Magento 2. Let’s go ahead and check how it works.
Redirects is a widely used approach not only in Magento but in most of other web applications. Saying “redirect” we usually mean a rule or a set of rules for sending user from one URL to another. Using Magento 1 you can easily handle redirects by writing just one line of the code, but in Magento 2, because of its new architecture based on Dependency injection, the process of building a redirect is a bit more complex. Let’s review a new redirect creation by building a simple extension that redirects user from a category page to a product view page if there’s only one product in this category.
