What is a Magento 2 Plugin?

A Magento 2 plugin, or an interceptor, is a tool for modifying existing classes in Magento 2. It can adjust the behavior of public class functions by intercepting function calls and executing code before, after, or around them.


This approach allows you to replace or extend the functionality of original, public methods for every class or interface. With Magento 2 plugins, you can alter a class's behavior without modifying the class directly.

Using these interceptors helps prevent conflicts among extensions that modify the same class or function. Magento 2 plugins are similar to extensions, often developed by third parties.

Plugins consist of three components:

  1. Type name: A class or interface observed by the plugin.

  2. Plugin name: An arbitrary identifier for the plugin used for configuration integration.

  3. Plugin type: The name of the plugin's virtual type or class.

What is a Magento 2 Extension?

A Magento 2 extension is a code package that adds specific functionality to Magento. It includes PHP and XML files in blocks, controllers, helpers, and models related to a particular business feature. Extensions are standalone code packages that can be customized or replaced without causing issues in other parts of the codebase. Unlike plugins, they offer complete solutions to problems, like introducing new payment gateways or shipping methods. Extensions are versatile and can be distributed and installed in Magento stores for tailored purposes.

Types of Magento Customizations: Magento Plugins and Extensions

1. Magento Plugins

  • Before Plugin: These plugins are called before an observed method in Magento. They must be named with the 'before' prefix followed by the observed method's name. ‘Before plugins’ can modify the arguments of the observed method. If changes are made, they should return an array of modified parameters. If no changes are needed, they return a null result.

  • After Plugin: After plugins are executed after the observed method is completed. They must be named after the observed method with the 'after' prefix. ‘After plugins’ can alter the initial result of the observed method and return the modified outcome.

Note: if the observed method declares a parameter as optional, the after method should do the same.

  • Around Plugin: Around plugins are unique as they run both before and after their observed method. They share the same name as the observed method with the 'around' prefix. These plugins can change the original function's result based on input data. It can also disable the execution of the original function. However, it's advisable to use ‘Around plugins’ only when necessary, as they can introduce stack traces and harm performance.

2. Magento Extensions

  • Magento Marketplace Extensions: Magento has a thriving product ecosystem that enables developers to create extensions that can be found in the Magento Marketplace. This official add-on store allows users to purchase and download third-party extensions and Magento themes to enhance their online stores. To maintain quality and ensure best practices, Magento maintains an Extension Quality Program. It combines Magento expertise, development guidelines, and verification tools to assess all marketplace extensions.

  • Out-of-the-Box Extensions: Besides the extensions available in its marketplace, Magento comes pre-packaged with additional third-party Magento eCommerce extensions called Vendor Bundled Extensions. These extensions undergo thorough testing before being included with any supported version of Magento. When you install Magento, these extensions are automatically included.

  • Custom Magento Extensions: Magento has a global community of developers, resulting in various ready-to-use third-party extensions. These extensions are often affordable and easily accessible. It's advisable to seek guidance from an experienced Magento developer when incorporating third-party extensions into your store.

Note: Overloading your store with unnecessary extensions can lead to complications and performance issues.

Limitations of Magento Customizations: Magento Plugins vs. Extensions

1. Magento Plugins

While Magento plugins offer flexibility and utility, they come with certain limitations. Avoid using Magento 2 plugins in the following scenarios:

  • Final methods and classes.

It can lead to conflicts in code when multiple extensions rewrite the same classes. Such conflicts can result in pages crashing until the code is resolved.

  • Website Security:

Installing third-party extensions carries inherent risks to website security. Since external communities often develop these extensions, ensuring their code doesn't create Magento vulnerabilities or backdoors is challenging. Third-party extensions may contain code conflicting with Magento's core code due to restrictions or protocols.

  • Website Speed:

Each Magento extension brings distinct functionality and features to your e-commerce site. However, most extensions require HTTP requests to load assets like CSS, scripts, and Magento images. It's essential to assess the impact on performance when adding extensions to your site.
