How angelabrilq/megaunistore works
1. Overall shape
- This repository is a two-part PHP application: a server-side backend for the operational system and a separate frontend site for public/marketing pages.
- The codebase is not a single SPA in the repository contents; despite the README’s mention of React, the checked-in frontend is mostly PHP/HTML static pages plus shared layout fragments.
2. Backend runtime and entry point
- The backend is served from backend/public/index.php, which acts as the front controller.
- Requests are then routed through backend/routes/web.php into controller classes under backend/app/controllers.
- Configuration is centralized in backend/config/env.php and backend/config/database.php, indicating a classic PHP application with environment-driven DB settings.
3. Layered backend structure
- The backend follows a clear controller → model → database pattern.
- Controllers coordinate request handling and view rendering.
- Models in backend/app/models represent the business entities and likely encapsulate DB access and domain logic.
- ControllerHelper.php suggests shared controller utilities, probably for responses, redirects, or common checks.
4. Core business subsystems
- The repository is organized around a multistore/retail management domain with separate modules for:
- Authentication and users: AuthController, UsuarioController, Rol, Permiso
- Sales: VentaController, MetodoPago, Cupon
- Cash register: CajaController
- Inventory: InventarioController, Producto, Inventario
- Catalogs/master data: Categoria, Proveedor, UnidadMedida, Impuesto, Tienda
- People management: Cliente, Empleado
- Returns and reporting: Devolucion, Reporte
- System setup: SetupController
- These modules are the main architectural boundaries for an implementation diagram.
5. Authorization and roles
- The presence of Rol and Permiso models plus a dashboard view set by role shows a role-based access control design.
- Role-specific dashboard pages exist for different operational personas: superadmin, sistema, admin_tienda, supervisor, vendedor, bodeguero, reportero, nomina, and cliente.
- This implies the backend gates both navigation and business actions based on user permissions.
6. Views and rendering model
- Backend views live in backend/resources/views, organized by module.
- This is a server-rendered UI approach: controllers select PHP views such as ventas/index.php, inventario/movimientos.php, usuarios/asignar_rol.php, etc.
- Shared layout templates exist under backend/resources/views/layout and dashboard, so the backend likely uses template composition rather than client-side rendering.
7. Data and persistence
- Database schema is defined through SQL files: backend/database/fase3_migracion.sql and the top-level backup.sql.
- This indicates the schema is a major part of the repo and likely the primary source of truth for tables and relationships.
- The model set closely mirrors the domain tables, so persistence is structured around relational entities for products, stores, sales, inventory, users, and transactions.
8. Operational flows
- The main transaction path is likely: user logs in → lands on role dashboard → performs sales, inventory, or cash operations → controllers update models/database → views show current state.
- Inventory and sales are tightly coupled through products, stock movements, cash register actions, and reports.
- Returns (devoluciones) and coupons add post-sale adjustments to the commerce flow.
9. Public/frontend site
- The frontend/public directory contains pages such as index.php, planes.php, soluciones.php, contacto.php, and testimonios.php.
- This looks like a public website / product marketing layer, separate from the administrative backend.
- Shared fragments in frontend/src/layout suggest a templated site shell for header/footer/navigation.
10. Boundary between public site and admin system
- The frontend and backend are separated by directory and responsibility:
- Frontend: informational pages, product/solution presentation, and public-facing content.
- Backend: authenticated business operations and data management.
- There is no evidence in the tree of a shared API consumed by a JS frontend; instead the system appears to rely on server-rendered PHP on both sides.
11. Error handling and resilience
- The backend includes explicit error views for 403 and 404, which indicates route-level and authorization-aware failure handling.
- This is consistent with a protected admin system where access denials and missing routes are expected runtime conditions.
12. Documentation as part of the architecture
- The document/ folder contains implementation notes, installation guides, architecture docs, and user/manual technical documentation.
- There is also a file named ANALISIS_REQUERIMIENTOS_VS_IMPLEMENTACION.md, suggesting the repo includes requirements traceability and phase-based implementation control.
- For architecture diagrams, this documentation likely reflects the intended module boundaries and deployment assumptions more explicitly than the README.
13. What matters most for a diagram
- Show two top-level surfaces: public site and authenticated backend.
- Inside the backend, show the main domains: auth/RBAC, sales, cash, inventory, catalogs, people, reporting, and system setup.
- Place the database as a central relational store feeding all backend modules.
- Treat the role-specific dashboards as presentation variants over the same backend domain services.
14. Notable implementation mismatch
- The README says frontend is React.js and backend may be Node/PHP, but the repository contents indicate a PHP-centric implementation with server-rendered views.
- If drawing the architecture from code, trust the file tree over the README: the actual shape is a monolithic PHP backend plus a static/templated public frontend, not a React SPA with a separate API layer.
