Magento Extensions and Modules: Technically, How They Differ Each Other?
Developers who are used to using Magento 1.x usually think that one extension/module/plugin is the same. In Magento 1.x there is no definition of plugin, although plugin should mean extension/module. This idea came from popular CMS platforms like; WordPress, Drupal and others.
In Magento 2 this has changed.
The modules we know about can be anything that introduces a completely new feature in Magento or rewrites some core Magento 2 features because we need a slight difference in functionality. At the same time, plugins can do something before, after or around it (before/after together). We can say that the Plugin in Magento 2 is a modified version of Observer in Magento 1.x.
Plugins are also called interceptors in Magento 2. The definition according to the Magento 2 devdocs is:
Plugins or interceptors are classes that modify the behavior of public class functions by intercepting function calls and executing code before, after, or around that function call. This allows you to override or extend the behavior of native public methods for any class or interface.
So can we say that modules and plugins are completely separate things? Although the two work differently, plugins cannot exist separately. So let’s say we need to create a module and write a plugin in the module to make the plugin work.
So all plugins are modules, but not all modules are plugins. However, there are some limitations to the plugin. Cannot be used everywhere.
The plugin cannot be used with any of the following:
Object instantiated before loading Magento\Framework\Interception
— Final Method
— Final classes
— Any class that contains at least one last public method
— Non-public method
— Static Method
— Virtual Types
So why use Magento plugins? The answer is; We use Observer in Magento 1.x for the same reason. Overriding class settings in a module can cause conflicts when multiple classes extend the same original class.
The plugin does not modify the class itself, nor does it rewrite the class settings, so there are no conflicts when using external modules that extend the same native class.
In Magento 1.x we have to rely on events for observers to work, but in plugins we can extend any feature.
