Step 2: Create Src folder and ExampleServiceOverrideServiceProvider.phpĬreating an src file is required and the Eventsubscriber folder is optional, Creating a Service provider file we need to follow the below rules. ymlĮxample_service_ name: Example Service Overrideĭescription: This is used to override the contrib private message module. The steps mentioned below will override the “PrivateMessageService”įirst of all, we will Prepare a Module skeleton by creating folder nameĮxample_service_override and create info file in it example_service_. Overriding the Private Message Contrib Module:Īs an example, I’m overriding the Private Message service named PrivateMessageService In a nutshell, we are overriding the Drupal service. We will extend Core/Contrib Service in our Custom module and add the extra code to override it. So how does this work in practice? Let’s see an example.Because it is not advisable to make changes in Core/Contrib modules code directly. Instead of forking the module, we can make it more generic. Auto Alters UI is great, but wed like to use Alttext.AI for the backend, from Microsoft Cognitive Services. Ok, I need to be injected, sure, but unless I’m not used, please don’t construct me… mkay? Problem/Motivation There are multiple competing services for describing whats on an image. Lazy services basically “tell” the container: Especially if it is expensive to do so - heavy on resources. However, if we have our custom service as a dependency which is used only for that one route, it doesn’t make sense to have it instantiated for both routes. Well, they probably are but anyway, see point 1. And second, they are not expensive to construct. For one, they are probably going to be instantiated anyway for other parts of the request. Of course, for “popular” services like the EntityTypeManager or form builders this is not a big deal. And even if only the second one depends on an injected service, the latter gets instantiated in both cases regardless. Most likely, when one method gets hit for the route, the logic of the second one doesn’t run. And this happens whether on that particular request that service is used or not.įor example, let’s imagine you have a Controller with 2 public methods used for 2 distinct routes. As you know, when we define a service and make it a dependency of something else, the service container will instantiate that service and inject it where it is needed. Feedback from several UT Drupal Kit customers has been that Twitter Publish is easy to use, and the appearance of the resulting Twitter feeds is actually. Not necessarily in the number of things they do (hopefully not) but in the time it takes for them to get instantiated. Inheriting from Symfony (in principle but not implementation), Drupal 8 allows us to define certain services as lazy.
