clean-architecture-frontend

To enforce clean architecture in Next.js, you structure your project into four layers: Domain, Application, Infrastructure, and Delivery. This blueprint enforces dependency rules to keep business logic framework-agnostic and uses ports with use cases to decouple rules from frameworks.

The best way to decouple business logic from Next.js UI components is by moving rules into a domain model and a corresponding use case. You then wire these use cases through a factory in the Delivery layer to execute them from Server Actions.

Dependency injection for use cases in a Next.js frontend works through a lightweight factory approach. This factory composes repositories and services, wiring the Application layer into the Delivery layer so the UI can execute use cases without direct framework coupling.

Yes, you can use ports and adapters with Next.js Server Actions by defining ports as interfaces and use cases as interactors. You wire them through a factory in the Delivery layer, allowing Server Actions to execute the use cases seamlessly.

You need a four-layer architecture for your Next.js application when you must separate concerns and maintainability at scale. Defining Domain, Application, Infrastructure, and Delivery layers ensures strict dependency direction for framework-agnostic business rules.

A limitation of using clean architecture patterns in Next.js is the added boilerplate from defining domain models, ports, and factories. You must enforce the strict dependency direction manually across the four layers to prevent framework code from leaking into the Domain.
