How tds-2/frontend works
1. High-level shape
- This is a single-page Angular frontend, generated with Angular CLI 21.x.
- The repository contains only client-side code; the business data lives in an external backend API.
- The app is centered on a single domain: colaboradores (employees/collaborators).
2. Bootstrap and application shell
- src/main.ts boots the Angular app.
- src/app/app.config.ts holds application-wide providers/configuration.
- src/app/app.ts, app.html, and app.css define the top-level shell/layout.
- app.routes.ts is the main navigation boundary: it wires the app’s screens together.
3. Primary feature subsystem: colaborador management
- The feature area is split into focused components under src/app/components/.
- panel is the central screen/container, likely the list or dashboard entry point for colaboradores.
- colaborador-detalle, colaborador-editar, and colaborador-eliminar represent the three core CRUD-oriented interaction surfaces for viewing, editing, and removing a collaborator.
4. Domain model boundary
- src/app/models/colaborador.ts defines the collaborator data shape used across components and services.
- This model is the contract between the UI and the backend payloads, keeping the UI components from depending directly on raw API response shapes.
5. Data access layer
- src/app/services/colaborador.service.ts is the only obvious service layer entry point.
- It acts as the HTTP boundary between Angular components and the backend API.
- The README specifies the backend endpoint as https://localhost:7192/api/colaboradorapi, so the frontend depends on a locally hosted HTTPS API during development.
6. Request/data flow
- User interaction starts in a route/component, most likely panel.
- Components call ColaboradorService for CRUD operations.
- The service sends HTTP requests to the backend API.
- Responses are mapped into Colaborador objects and rendered back through the detail/edit/delete components.
- This creates a clear one-way flow: UI event → service → API → model → UI update.
7. Routing and screen composition
- The app appears to use Angular’s standalone routing approach rather than a large module hierarchy.
- app.routes.ts is the key architectural file for screen-level separation.
- The route structure likely maps the panel and collaborator actions to dedicated views, keeping each operation isolated in its own component boundary.
8. Testing boundaries
- Unit test files exist for app and panel, indicating component-level testing rather than full-system testing.
- The README notes ng test uses Vitest, so the test stack is Angular + Vitest-based unit testing.
- This suggests tests focus on component behavior and rendering, not backend integration.
9. Build and runtime environment
- The app runs in the browser via Angular’s development server (ng serve) on http://localhost:4200/.
- Production builds are produced with Angular CLI and emitted to dist/.
- Tooling is standard Angular CLI, with TypeScript, npm, and Angular 21 as the core runtime/build stack.
10. Static assets and presentation
- src/styles.css and per-component CSS files indicate styling is split between global and feature-local presentation.
- public/ holds static assets served directly.
- The presence of separate HTML/CSS/TS files per component shows a conventional Angular component architecture with clear separation of view, behavior, and styling.
11. System boundary summary
- The important architectural boundary is not internal microservices, but frontend vs backend.
- Everything under src/app/ is presentation, routing, and API orchestration.
- The external backend API owns persistence and business data; the Angular app owns user interaction, state display, and form-driven CRUD flows.
12. What to draw in an architecture diagram
- Draw the browser app as the central client.
- Inside it, show: app shell/bootstrapping, routing, collaborator UI components, model layer, and service layer.
- Draw an external backend API endpoint as the only server-side dependency.
- Add the testing toolchain and Angular CLI build/dev server as supporting infrastructure around the app, not part of the runtime request path.
