Hexagonal Architecture in Angular - A Practical, Minimal Use Case

In today's article, we are gonna learn a bit more about hexagonal architecture with Angular. This article is for people who are curious about hexagonal architecture and already know about Angular. Throught this article, we'll build a small use case. The repository with the final code can be found here The structural Drift of Growing Angular Applications Angular applications rarely collapse overnight. They drift. At the beginning, the structure is clean: a component, a service, an HTTP call. The responsibilities feel obvious. Over time, features accumulate. Deadlines compress. The code adapts locally to solve immediate problems. Gradually, architecture dissolves into convenience. Business Logic Leaking into Components and Services Components start by handling view concerns: rendering, user interaction, state binding. Soon, validation rules appear in the component. Then conditional business flows. Then domain invariants expressed as if statements directly inside submit() methods. Service
