Magento 2 Admin Module Development

What is the architecture of Magento 2 admin module development like?

When it comes to the Magento 2 admin module development, it is important to mention the architecture of Magento 2. The purpose behind its source code build is to make it extensive and modularized. Thereafter, you can customize and adapt it as per the requirements of the projects.

In terms of customization, the main focus is to change the platform code’s behavior. In most cases, this signifies making changes to the core code altogether. When you are using the best practices in Magento, you do not have to do this most of the time. Yet, the stores can use the latest feature releases and security patches reliably enough.

There are two types of systems available in terms of architecture; MVVM or MVC systems. The module development in Magento 2 falls under the former category. However, this has more layers and robust usage than the latter even though essentially they are very similar. The layers under the MVVM (Model View ViewModel) system are:

  • Model– It holds the business logistics, and focuses on ResourceModel, an associate class for access to the database. Not to mention, these work with the help of service contracts to improve and expose the other layer functions.
  • View– This is the overall HTML, or more specifically, the layout and structure visible for users. The PHTML files that work with modules include this factor. All the PHTML files relate to each of the ViewModels present inside the files of Layout XML. These Magento 2 development essentials are also called binders.
  • ViewModel- This works closely with the aforementioned layer, and shows only the relevant data to the layer of View. The Block classes in the module handle this in Magento 2. This works as an alternative to the MVC system’s Controller role, and this handles the flow of users. Indeed, it gets all the requests and informs the system to allow the viewer to redirect to a separate route.

The Mageplaza module development of Magento 2, for example, includes some particular folders. Some of these folders are mentioned above:

  • Block
  • Model
  • Controller
  • View

And the others are mentioned below:

  • API- Data interfaces, interfaces of defining service, and service contracts
  • Etc– The XML files for configuration- this includes the parts of the module like models, observers, routes, blocks, etc, inside the folder. The non-core modules can use these files to override the core module functions.
  • i18n– Any Magento customization company can handle translation using the internationalization CSV files in this.
  • Helper– These classes hold the codes that work with multiple application layers.
  • Observer– This folder holds the models that observe the system events. In case such an event occurs, the observer facilitates the model that focuses on the business logic needed for the task.
  • Test– These include the unit tests
  • Setup– Migration classes; this affects data and schema creation
  • Ui- UI elements like forms and grids that work in the admin application

Overall, when you are developing the admin module of Magento 2, you have to consider these parts of the architecture. That would help you set up the programs and create projects later.
