For example, in the Cms module, helper classes are responsible for preparing HTML for presentation to the browser.

#DEV DOC MAGENTO CODE#

Helper: Helper classes that hold code used in more than one application layer.The etc files can also be used by non-core modules to override the functionality of core modules. etc: Configuration XML files-The module defines itself and its parts (routes, models, blocks, observers, and cron jobs) within this folder.Controller: Controllers, responsible for handling the user’s flow while interacting with the system.Block: The ViewModels of our MVVM architecture.Api: Service contracts, defining service interfaces and data interfaces.The overall architecture is described below ( source):Įach folder holds one part of the architecture, as follows: On MVVM, the controller is only responsible for handling the user flow, meaning that it receives requests and either tells the system to render a view or to redirect the user to another route.Ī Magento 2 module consists of some, if not all, elements of the architecture described above. Note that this was usually part of the Controller role of an MVC system. In Magento 2, this is handled by the module’s Block classes. The ViewModel interacts with the Model layer, exposing only the necessary information to the View layer.The layout files might also assign JavaScript files to be used in the final page. PHTML files are associated to each ViewModel in the Layout XML files, which would be referred to as binders in the MVVM dialect. This is achieved in the PHTML files distributed with modules. The View is the structure and layout of what a user sees on a screen - the actual HTML.Models rely on service contracts to expose their functionality to the other layers of the application. The Model holds the business logic of the application, and depends on an associated class-the ResourceModel-for database access.Below is an explanation of each of the layers of a MVVM system: While being closely related to its sibling Model View Controller (MVC), an MVVM architecture provides a more robust separation between the Model and the View layers. Magento 2 is a Model View ViewModel (MVVM) system. In Magento, if you are following best practices, this is something you can avoid most of the time, making it possible for a store to keep up to date with the latest security patches and feature releases in a reliable fashion.

In the majority of systems, this means changing the “core” code. The end goal of that approach is to allow it to be easily adapted and customized according to each project’s needs.Ĭustomizing usually means changing the behavior of the platform’s code. Magento’s architecture was designed with the intent of making the source code as modularized and extensible as possible. In case you are not very confident about your OOP skills, it might be a good idea to review it before beginning your work with the platform. Magento was initially created by a team of experienced Java developers, and their legacy can certainly be seen throughout the codebase. It is important that you have a good understanding of the following technologies/concepts in order to follow the rest of this article:įrom all of the above, OOP is probably the most important one.

Now it’s completely safe to say that Magento 2 is a much more robust piece of software than its predecessor. A little over one year down the road, and the improvement is visible, even though not all of the problems mentioned have been totally solved.
