The website development world, is really an amazing one, especially when you know what you are doing. In today’s article, we are going to continue our conversation on Drupal 8 about Plugins, so that we may be able to use them, to extend Drupal 8.
If you as a developer want to be able to extend Drupal 8 by writing code, then Plugins are one way that you can accomplish that. In an object-oriented way, which is extensive, functionalities can be added to a website using a module that was developed through a Drupal 8 plugin API. When you want a module to provide additional things to your website, through the same interface; you can accomplish this, by using a plugin to fulfill any needs.
It should be considered required knowledge to be able to implement an existing plugin if you want to call yourselves a module developer. The basic framework or interface for the functionality is defined by the controlling module; while plugins with behaviors can be created by other modules.
A plugin manager service manages plugins, which are grouped into plugin types. A plugin factory is used to instantiate plugins and is discovered through a plugin discovery method used by the plugin manager.
You can solve many different types of problems, for different situations, using a plugin; however, developers cannot transfer a finished chunk of code from one system to another, this is not what plugins are. Blocks, Render API elements, Image manipulation effect, and field types, widgets and formatters are all examples of applications, which use the plugin pattern.
A new plugin instance should be implemented, every time a developer wants to add new functionality to a system that’s already using the same plugin. Whenever new configuration options must be added to Drupal, for users to have the ability to choose that option, then a plugin would be ideal to add such a feature.
Developers who want to write modules, which extend Drupal’s functionality, must also learn about which plugins are available, and also be able to use them depending on the case scenario. You can use the Drupal console if you want to know about the existence of plugins if you just type this code onto the Drupal console.
You will see a list of available plugins, which are at your disposal for use; this is all good, but you must be able to use them as well after you discover them. As we mentioned before, you’d have to be able to use your plugin, once you have found it, if not then finding it won’t do a developer any good.
On the next topic, we will focus on implementing a plugin of any type. The plugin manager will only find plugins which have well-written code or at least code that makes sense to that plugin manager.
It would make sense for a developer to know where the implementation of a plugin and its metadata should reside in the code. The plugin manager must be able to find your newly created plugin, to provide its functionality to users based on the need the plugin must fulfill.
