Study Notes

Service Contracts in Magento 2

Stable API Definition: Service Contracts define a set of interfaces to provide a stable API for module interactions, allowing for consistent communication between different components.
Business Logic Encapsulation: They encapsulate the business logic, ensuring that the implementation details are hidden, which promotes better design and maintainability.
Improved Module Interoperability: By using standardized interfaces, Service Contracts enhance module interoperability, enabling developers to create modules that can easily work together without compatibility issues.
Version Control: Service Contracts facilitate versioning, allowing developers to alter or extend the functionality without breaking existing integrations.
Increased Testability: The use of interfaces improves testability, making it easier to write unit tests for business logic without needing to rely on specific implementations.
Clear Contracts for Developers: They provide clear contracts for developers, ensuring that they understand what methods and behaviors to expect from different services, leading to more reliable code.
