Back-end development and customization are key aspects of any ecommerce platform, and Magento 2 has introduced several improvements in these areas compared to Magento 1. In this Magento 2 tutorial, we will examine the differences between Magento 1 and Magento 2 regarding back-end development and customization, focusing on modular architecture, dependency injection, improved extension management, service contracts and APIs, and simplified theme management. These enhancements make the life of a Magento 2 developer easier, streamlining the development process and allowing for more efficient customization.

Modular Architecture

Magento 2 has adopted a modular architecture, which offers several benefits over the monolithic architecture of Magento 1:

Better Code Organization

The modular architecture allows for more organized and maintainable code, making it easier for Magento 2 developers to understand and work with the codebase.

Enhanced Customization

With its modular design, Magento 2 enables developers to make targeted customizations without affecting other parts of the system, reducing the risk of conflicts and errors.

Dependency Injection

Magento 2 introduces dependency injection, a design pattern that promotes loose coupling between components, resulting in more maintainable and testable code:

Improved Code Flexibility

Dependency injection allows Magento 2 developers to swap out specific components without affecting the rest of the system, making it easier to adapt and evolve the codebase.

Simplified Testing

Dependency injection enables more straightforward unit testing, as dependencies can be easily mocked, allowing developers to focus on testing individual components.

Improved Extension Management

Magento 2 offers improved extension management, making it simpler for developers to install, update, and remove extensions:

Component-based Structure

Magento 2 organizes extensions into components, making it easier for developers to manage and maintain individual extensions.

Reduced Extension Conflicts

Magento 2 uses a plugin system that helps minimize conflicts between extensions, allowing developers to seamlessly integrate multiple extensions into their projects.

Service Contracts and APIs

Service contracts and APIs are essential for integrating Magento 2 with third-party systems and services. Magento 2 has made significant improvements in this area:

Comprehensive API Coverage

Magento 2 offers a robust set of APIs, covering a wide range of functionality, making it easier for developers to integrate with external systems.

Standardized Service Contracts

Magento 2 introduces service contracts, which define the interfaces for specific modules, ensuring a consistent and standardized way of interacting with the system.

Simplified Theme Management

Magento 2 provides a more straightforward approach to theme management compared to Magento 1, simplifying the process for developers:

Inheritance-based Theme Structure

Magento 2 uses an inheritance-based theme structure, enabling developers to easily create child themes that inherit the functionality and styling of parent themes.

Streamlined Theme Customization

With its simplified theme management, Magento 2 allows developers to efficiently customize the appearance of their stores, with a clear separation between theme files and core files.


In this Magento 2 tutorial, we’ve explored the key differences between Magento 1 and Magento 2 in terms of back-end development and customization. Magento 2’s improvements, such as modular architecture, dependency injection, improved extension management, service contracts and APIs, and simplified theme management, offer a more efficient and streamlined development process for Magento 2 developers. As a result, Magento 2 is the ideal choice for ecommerce businesses looking to enhance their online stores and harness the full potential of the platform’s customization capabilities.
