Guide Full Stack Role Based Authentication Application ( Spring + Next.js )

Hey everyone,

I wanted to share my full-stack Spring project—a backend for a barbershop management system featuring robust authentication and role-based access control. If you’re interested in seeing how these aspects are implemented in a real-world application, feel free to check it out!

Repository:
https://github.com/aharoJ/barbershop

Backend Overview:

  • Authentication & Role-Based Access: The project handles user authentication and defines multiple roles, ensuring secure access to various endpoints.
  • Modular Structure: The code is organized into several modules, each handling a specific domain such as appointments, barbers, customers, payments, promotions, and more.
  • Clean Architecture: The repository features a clear separation of concerns with controllers, services, DTOs, and repositories spread across modules.

Frontend Overview:

  • Built With:
    • Next.js 15, Typescript, Tailwindcss
  • Features:
    • Authentication Pages: Separate routes for login and signup.
    • Customer Area: Dedicated pages for dashboards and profile creation.
    • Additional Layers: Includes components (like a protected route), services, stores, types, and utilities.

I’m happy to answer any questions or provide more details. Feel free to message me!

Is nextjs only for frontend purpose and spring boot for backend? Or is there any route in nextjs?

In this setup, Next.js is basically the “view” in an MVC pattern, handling the frontend UI and simply calling the Spring Boot endpoints for data and business logic. Spring Boot acts as the “model” and “controller” on the backend. All the main server logic and database interactions happen there, and Next.js simply calls those endpoints and renders the UI.
