In this blog, we are going to learn very important concepts Injectable and Non-Injectable Objects in Magento 2.<\/p>\n\n\n\n

What are Injectable Objects?<\/strong><\/p>\n\n\n\n

Injectable objects in Magento 2 are classes that can be instantiated and managed by the Dependency Injection (DI)<\/a> container. They are typically used for services, repositories, and other core functionalities.<\/p>\n\n\n\n

You can also check out our Dependency Injection (DI)<\/a> blog for a better understanding of DI functionalities.<\/p>\n\n\n\n

Here’s an example of an injectable object in Magento 2:<\/p>\n\n\n\n

namespace Vendor\\Module\\Model;\n\nuse Vendor\\Module\\Api\\CustomInterface;\nuse Vendor\\Module\\Model\\Dependency;\n\nclass CustomModel implements CustomInterface\n{\n    protected $dependency;\n\n    public function __construct(Dependency $dependency)\n    {\n        $this->dependency = $dependency;\n    }\n\n    public function performAction()\n    {\n        \/\/ Use the dependency to perform the action\n        $this->dependency->doSomething();\n    }\n}<\/pre>\n\n\n\n
In the example above, the CustomModel<\/strong> class has a dependency on the Dependency<\/strong> class, which is injected through the constructor. By following this approach, we can easily manage and replace dependencies, making our code more flexible and maintainable.<\/p>\n\n\n\n
What are Non-Injectable Objects?<\/strong><\/p>\n\n\n\n
Non-injectable objects in Magento 2 are those that cannot be automatically instantiated and managed by the DI container. These objects are typically instantiated using the new<\/strong><\/code> keyword directly in the code. Non-injectable objects may still have dependencies, but their instantiation is not controlled by the DI container.<\/p>\n\n\n\n
Let’s consider an example of a non-injectable object:<\/p>\n\n\n\n
namespace Vendor\\Module\\Model;\n\nuse Vendor\\Module\\Api\\CustomInterface;\nuse Vendor\\Module\\Model\\Dependency;\n\nclass CustomModel implements CustomInterface\n{\n    public function performAction()\n    {\n        $dependency = new Dependency();\n        \/\/ Use the dependency to perform the action\n        $dependency->doSomething();\n    }\n}<\/pre>\n\n\n\n
In the above example, the CustomModel<\/strong><\/code> class instantiates the Dependency<\/strong><\/code> object directly using the new<\/strong><\/code> keyword. This approach tightly couples the classes together, making it difficult to replace dependencies or write unit tests.<\/p>\n\n\n\n
When to Use Injectable and Non-Injectable Objects?<\/strong><\/p>\n\n\n\n
It’s recommended to use injectable objects whenever possible, as they promote flexibility, maintainability, and testability. Injectable objects allow for easy swapping of dependencies and facilitate writing unit tests by enabling the use of mock objects.<\/p>\n\n\n\n
Hope this will be helpful.
