Review Change Stack

📝 Walkthrough

Walkthrough

The CRUD application now uses a typed TodoStore with Angular signals. TodosHttpService handles API requests. AppComponent renders store state and delegates loading, update, and delete actions.

Changes

Todo CRUD flow

Layer / File(s) Summary
Todo contract and HTTP service
apps/angular/5-crud-application/src/app/app.interface.ts, apps/angular/5-crud-application/src/app/http.service.ts
Defines ITodo and adds HTTP methods for todo retrieval, updates, and deletion.
Signal store operations and tests
apps/angular/5-crud-application/src/app/todo.store.ts, apps/angular/5-crud-application/src/app/todo.store.spec.ts
Adds signal-based todo and loading state management for CRUD operations, with tests for success, errors, and state updates.
Component store integration
apps/angular/5-crud-application/src/app/app.component.ts
Renders store state, shows a loading overlay, and delegates initialization, update, and delete actions to TodoStore.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 2a4b1

The todo loading indicator can turn off before all requests finish or remain stuck after a failed request, causing users to see an inaccurate or blocking interface. The change is otherwise bounded, but merge should proceed with explicit follow-up to make loading state handling request-safe.

- Around line 18-20: Update the Todo store methods using finalize, including the
getAll, create/update, and deleteOne request flows, so the shared isLoading
signal remains true while any request is active and is cleared only after all
active requests finish; track active request count or serialize operations
consistently across all three methods.
