Onion Architecture

Onion Architecture - C#

The Onion Architecture aims for loose coupling and high testability by organizing code into concentric layers. The core layer contains business rules and entities, completely independent of infrastructure concerns. Outer layers represent interfaces, data access, and presentation. Dependencies point inward – …

Onion Architecture - TypeScript

The Onion Architecture aims for loose coupling and high cohesion by organizing code into concentric layers. The innermost layer represents the Enterprise Rules (core business logic, entities). Middle layers are Interface Adapters (controllers, presenters) that translate data to and from the core. The outermost layer is …

Onion Architecture - JavaScript

The Onion Architecture aims to achieve a loose coupling between business logic and infrastructure concerns like databases or UI frameworks. It structures the application in concentric layers: Domain (core business rules), Application (use cases orchestrating domain models), and Infrastructure (external implementations …

Onion Architecture - Python

The Onion Architecture aims for loose coupling and high cohesion by organizing code into concentric layers. The core layer contains business rules, independent of any external concerns. Surrounding layers represent interfaces (ports) to adapt these rules to specific technologies like databases or UI frameworks. …

Onion Architecture - Java

The Onion Architecture is a design pattern focused on achieving loose coupling and increased testability by organizing code into concentric layers. The innermost layer represents the domain – core business logic with no dependencies. Surrounding layers represent domain services, data access, and infrastructure (UI, …
