A 7-layer Laravel architecture separates concerns across Presentation, Request, UseCase, Service, Repository, Model, and Resource layers to ensure testable and maintainable applications. It establishes clear boundaries for specific backend logic responsibilities.

You can enforce dependency rules in a layered Laravel backend by applying downward-only dependencies and configuring Deptrac static analysis. This validates layer boundaries during code reviews and prevents unauthorized upward references.

To start planning a Laravel backend architecture, map your project modules to the seven defined layers and set up Deptrac rules during Phase 1. Use the provided decision checklists and structure templates to guide scaffolding.

You can apply this layered design to existing Laravel projects by mapping current modules to the seven layers and enforcing downward-only dependencies. Use the reference docs and decision checklists to guide progressive code reviews.

This architecture approach utilizes design patterns within its UseCase and Service layers to organize business logic. It provides a structured blueprint that defines specific responsibilities for each layer to maintain scalable backend code.

The best way to organize UseCases and Services in Laravel is assigning specific responsibilities within a 7-layer architecture. UseCases handle application workflows while Services manage domain logic, ensuring clear separation of concerns.
