The architecture of Magento 2 aims to make the source code as comprehensive and adaptable as possible. The main objective of this strategy is to make it easy to adjust and adapt to the project requirements. Each logic and functionality of the company is constructed as modules. Each module can function as an independent entity.
A ViewModel (MVVM) architecture is available in Magento 2. This MVVM architecture provides a considerably more solid separation between the model and the visual layer, as the model view controller is closely related (MVC).
Description of MVVC:
Model
Like the MVC, the data management and essential information description logic are necessary for the application. It has the application's business logic and depends on the associated class – the database access Resource Model. The model responds to the request from the viewpoint.
View
The view is a graphical interface on the screen. It is capable of showing the user request-response. The view is a framework or layout that shows the data in a certain format. Views indicate that "the way your data looks." It subscribes to the changes of the ViewModel property values or commands.
ViewModel
The ViewModel connects with the layer of the model and only provides the view layer with essential information. The Block Classes in Magento 2 module handles this. It is vital to note that this is typically part of the role of the MVC controller. In MVVM, the controller handles the user's flow, such that requests are accepted and that the system can either display a view or redirect the client to another pathway.
According to the official documentation, Magento 2 is divided into four layers.
- Presentation Layer
- Service Layer
- Domain Layer
- Persistence Layer
Presentation Layer
The top layer of Magento 2 architecture is the presentation layer. When we interact with Magento's web interface, we deal with the layers of code for the presentation.
Service Layer
The middle layer and domain layer is the service layer. It offers a connection between the presentation and domain layer and resources specified data. The service layer performs service contracts defined using a PHP interface.
Domain Layer
For business logic, the domain layer is responsible. It does not include information specific to a database or resource. The domain layer defines the generic Magento databases or business logic models.
Persistence Layer
It outlined the resource model accountable in the CRUD (Create, Read, Update, and DELETE) requests for information gathering and manipulation in the database.
Magento 2 vs Magento 1
Architecture
- Magento 1 supports PHP 5.2, and Magento 2 supports PHP 5.6 versions of PHP.
- Magento 1 functions with HTML, CSS, and Magento 2 uses HTML5, CSS3, as well as composer.
Support
Until June 2020, Magento 1 has been extended by the Magento team. This means that Magento stops upgrading and distributing the latest security, corrections and extensions on its side.
Magento 2 has, on the other hand, started up advanced features Like PWA integration, page building, easy management and automation.
SEO & Security
The catalogue page contains rich snippets, improving the search results in SERPs, for the passwords use the reinforced hazard algorithms (SHA-256). This strengthens the password for the type of assaults dictionary.
Scheme.org has been launched by Magento 2.0 to enhance the SEO of stores.
