De-coupling Frameworks
Many developers commit the error of stuffing business logic inside their framework controllers or models. When framework changes happen (e.g. updating database packages or switching dependencies), the entire codebase breaks. Clean architecture solves this by separating rules into individual, testable folders.
1. The Repository Pattern
Repositories act as database intermediaries. Controllers never execute raw Eloquent or query builder codes directly. Instead, they command a repository interface:
interface ConsultationRepositoryInterface {
public function getPending(): Collection;
}2. The Service Layer
Services manage orchestrations (e.g., creating a user, dispatching welcome emails, and saving logs). By encapsulating this inside service functions, we can call them from APIs, Admin CMS forms, or terminal commands without copy-pasting code.
