Top 7 Magento Development Best Practices

Magento is a platform built on open-source technology and written in PHP, which helps developers create E-Commerce websites. Magento development is well-known for its flexibility in meeting various customers’ demands.

However, so many different pieces are involved, so it’s important to have a set of procedures in place to keep the codebase nice and tidy. Implementing a formal process, known as Magento development best practices, to standardize repeatable tasks helps ensure the reliability of your store, speed up the code preview process, and prevent unwieldy situations from occurring in the first place.

Magento Development Best Practices

#1: Coding Standards 

The first Magento development best practice is coding standards. Magento Coding Standard is the official coding standard built for and recommended by Magento. Make sure that your Magento coding standards are based on Zend coding standards, PSR1, PSR2, and PSR4. Following these standard conventions gives your code a professional look while making it tidier and easier to read.

Edit core files can break the default Magento application’s behavior and lead to many vulnerabilities, so guarantee that you always follow coding standards. Because your project or task requires a fast turnaround, all the developers usually lose focus on adhering to standards. By skipping the standards, you may get quick results, but your work will lack quality, and progress will stall quickly.

Another great reason to follow the Magento development best practices of Coding Standard is that by following these guidelines, your code has a much higher rate of quality and compatibility with the extended Magento ecosystem. Magento Coding Standard is used for automated reviews for Magento Marketplace modules. It also utilizes the compatibility with Magento instances running on the Magento Cloud.

#2: Module Development 

Magento consists of the core code and optional components that can enhance or replace the core code. So, if you need to change the way that Magento development works, Magento’s architecture allows improvements by letting you develop your own components, like creating a module or a separate theme. By developing a new module, you can test your changes on different installations, disable the functionality if a problem arises, and reinstall the functionality when you upgrade your platform.

While developing any module, one of Magento’s development best practices is to ensure is that proper naming conventions are being followed and case. Maintaining consistency while naming conventions for files, folders, methods, and classes is a must in developing a new module from scratch. If you got lost in creating additional coding, then look at the Magento source code. Magento code is often a source of inspiration when you are approaching something new.

#3: Reuse Code 

Reducing the redundant code is the most basic and most effective among Magento development best practices for increasing the performance of any code. Instead of using the same code in multiple places, create a single class or method, reference it when required, and make sure to reuse code as much as possible.

Another key consideration here is to write generic code in Magento development. The code you write should be small, focused, and should provide a generic solution. This will let you re-use these pieces again in future development.

#4: Utilize Your Observer  

Observers are dynamically injected into the execution flow, making it capable of modifying the behavior of a Magento application. Poorly designed and coded observers can cause issues, instabilities, or otherwise break the application.


Try to keep your observer small and efficient by avoiding complex computations as much as possible. The following tips can ensure that the observer in your Magento application will run seamlessly:

  • Avoiding complex computations in the code of observer can increase Magento development efficiency. Especially in a scenario where the observer frequently listens to a dispatched event, efficiency will play a great role.
  • Excluding unnecessary logic inside the observer code. The classes used by the observer should only contain business logic.
  • The observer’s location also plays a great role in defining Magento application efficiency. For instance, if the observer is needed only for the events on the front end, it should be declared in /etc/frontend/events.xml file instead of the global /etc./events.xml file.
  • Cyclical event loops refer to a state where an observer is stuck between a recurring task. This is usually caused by several interlinked events that are being called by the same observer. Therefore, Magento’s development best practice is that the observer should not dispatch an event that it immediately listens to or will listen to in the chain of events.
  • Observers listening to the same event should not be invoked in any specific order. The execution of one observer may rely on another and lead to a delay in the overall function if there is an invocation order.

#5: Extend Layout 

Instead of duplicating extensive page layouts or configuration codes and then modifying what you want to change, Magento development’s best practice is creating an extending layout file containing the changes you want.

#6: Override Layout 

If the number of customizations is large, you cannot customize the layout by extending the existing ones. In this case, Magento development’s best practice is to use the overriding function for the needed layout file. This means that the new file that you place in the theme will be used instead of the parent theme layout file of the base layout file.

#7: Clear Cache 

Forgetting to clear or disable caching can be very troublesome to your Magento development process. It is recommended to clear your cache before doing visual checks for your theme to make sure the content displayed is correct.

While you’re developing Magento components (modules, themes, and language packages), your rapidly changing environment requires you to clear certain directories and caches periodically. Otherwise, your code runs with exceptions and won’t function properly.



In conclusion, those are Magento development best practices that should be followed to ensure optimized code for your Magento E-Commerce website.
