Magento Best Practices
Magento has both CMS static blocks & widgets. Where widgets offer a high level of functions, and the CMS static blocks are used to place text and images on a page.
If your primary focus is building your business and online sales, Magento could be ideal. Magento gives you a choice of managed cloud hosting with Magento Commerce.
Magento is one of the most popular used CMS in the world. It is purely an eCommerce platform, which makes its ranking alongside a broader CMS platform with a good representative quality.
Let's have a look over the following list of Magento Best Practices:
Use Magento generic CSS classes whenever possible.
A Magento default installation provides you several CSS classes that you can use to make a new store template and use that className for new templates. Various third-party extensions use that className for design Integration.
Design your code to be replaceable
A replaceable design code will be much modular & loosely coupled, which makes updates & improvements easier and also make it reusable.
Always document your code.
You should always prefer to use PHPDoc in your projects. In case of any error, you can easily find the solution, and it's always easier to explore documented code. It will be also beneficial for those programmers who have to work with your code.
Composition over inheritance
Class inheritance is the object-oriented programming concept that deals with code reuse and extending the behavior of a base class, which was preferred for Magento 1 development.
Object composition is the programming concept of combining class objects and data types to create a more complex class. The classes and data types are used together to produce the desired functionality.
For Magento 2 extension development, we encourage the use of object composition over class inheritance. Using composition over inheritance makes your extension easier to maintain when class changes occur and update when new features need to be implemented.
Always explore core abstract classes during your work with Magento.
It helps you to make your code more effectively such as many developers write their methods for checking the status of their extensions, but only a few of them use method is ModuleEnabled() from Mage_Core_Helper_Abstract
Be consistent with case and naming conventions
You should be consistent in your naming conventions for files, folder names, classes, and methods. Following standard conventions makes your code easier to read and look professional.
Not following this practice is a code standards violation and impacts your extension’s readability and maintainability.
Avoid creating helper classes
Helper classes are filled with static methods that do not fit anywhere else and consider as anti-patterns that work against the principle of object-oriented programming.
A helper class functions as a catch-all for random methods breaks the single responsibility methods because it can solve various problems in a single class. you can also rewrite the code and shift those functions into the relevant classes they should work on.
Observer Overriding
Observers are the ones who are dynamically injected into the execution flow and capable of modifying the behavior of the Magento application development. It's a general practice to replace parts of your codebase with new pieces as bugs are found.
Writing replaceable code in your codebase makes this practice simple & more efficient. On the other side, poorly designed & coded observers can cause issues, instabilities and can break the application.
Write and utilize reusable code
In general, you can reuse code as much as possible to prevent code duplication and avoid using duplicate code, which can be hard to maintain. Now here you can create a single class & reference it when required instead of copying and pasting the same code throughout the extension.
It would be better than the code you write should be small, focused, & provide generic solutions so that you can also reuse code in future development.
Layout XML
In the current version of Magento 2 its layout definition has been updated to more advanced one to restrict the modifications you can apply in template files same as previous versions and With new additions of a container, move, reference block, reference container, move, update and argument tags the complete definition for layout XML results.
Using around plugins
The only use case for around method plugins is when you need to terminate the execution of all further plugins and original methods. Apart from that, avoid using around method plugins when they are not required because they increase stack traces and affect performance.
Test your code
A test helps what your code does under different conditions & defines its functions. You have to make sure that your tests cover a variety of conditions to prevent the introduction of bugs while adding new code.
Wrapping Up
It is essential for any magneto web store owner that your Magento development agency is aware of all these development best practices.
