Make your Magento 2 theme faster

Magento 2 is known to be a powerful and feature-rich eCommerce platform. It delivers decent page load times but might be quite sluggish under heavy customizations.

Part of the performance problem might be a poorly developed custom theme. On one hand the default Luma and Blank themes are quite fast. On the other hand some of the customized themes are slow and could make your online shop a nightmare to buy from.

Dynamic fields in system configuration

System configuration is a very useful feature of the Magento platform. At the same time, it’s easy to create new configurations for your own custom solutions. We’ve previously discussed on how to add new system configurations with different fields. Today I would like to describe one more type of fields, which can be used depending on your needs. This is a dynamic field block. At times, managing complex data through system configurations is necessary, especially when the number of records to be added isn’t predetermined. In this case it’s impossible to create the exact fieldset in a system configuration tab. Thus, dynamic fields prove to be invaluable.

Upgrade Magento to the latest version

It’s well-known that the Magento team announces new platform upgrades quite often. There is a minor upgrade every second month and a more critical upgrade with new features and more changes to the core almost every quarter on average. If we look back, since the release of Magento 2.0 in November 2015 there were around 30 releases for Magento Open Source and Magento Commerce. Looks like a lot, doesn’t it? So the question arises: do these changes actually bring any value to the website?

Custom Module upgrade: PHP Serialiazed to JSON

After the latest Database data format changes in Magento 2.2.x version, there is a need to convert existing PHP serialized data to JSON format. The new release provides upgrade scripts that convert Magento serialized data. But how to deal with custom extensions, which also use automatic serialization mechanism provided by Magento framework? Thankfully, Magento took care of that too.

Custom Module upgrade: PHP Serialiazed to JSON

The new Magento 2.2 release replaces the usage of default PHP serialized format to JSON format. The release also upgrades scripts that convert Magento data that is stored in serialized format e.g. Magento\Sales\Setup\SerializedDataConverter, Magento\Sales\Setup\SalesOrderPaymentDataConverter, Magento\Framework\DB\DataConverter\SerializedToJson classes. These major changes may affect the correct functionality of already existing custom modules and related data that is stored in the database.

Uninstall modules in Magento 2

One of the shortcomings of Magento’s first version was the inability to clean up module data from the database upon its removal. This is a common situation when you uninstall an extension but all the related data remains in the database. You can only get rid of it manually. It is inconvenient especially if the module has created a bunch of new tables, custom attributes, system configurations etc. In such cases, an automatic data removal tool would be highly beneficial.

In Magento 2 there is a great feature, which allows to create an uninstall script for your module. Let’s find out how it works.

How-to-hide-your-Magento-2-version

Having a particular version of the software easily discoverable makes hacker’s job easier and allows automated scrapers to gather a database of URLs with particular software versions that can be used at an event of security vulnerability discovery for attacks. Of course, hiding the Magento version won’t be enough to secure your store, but it is just a simple step to take, just like changing your admin URL that makes store a little bit more secure.
