New Angular Feature

Routes File

import { Routes } from '@angular/router';

export const {featureName}Routes: Routes = [
  {
    path: '',
    loadComponent: () =>
      import('./list-view/{feature-name}-list.component')
        .then(m => m.{FeatureName}ListComponent),
  },
  {
    path: ':id',
    loadComponent: () =>
      import('./details/{feature-name}-details.component')
        .then(m => m.{FeatureName}DetailsComponent),
  },
];

Register in app.routes.ts:

{
  path: '{feature-name}',
  loadChildren: () =>
    import('./features/{feature-name}/routes')
      .then(m => m.{featureName}Routes),
},

Service Pattern

@Injectable({ providedIn: 'root' })
export class {FeatureName}Service {
  private http = inject(HttpClient);

  list(params?: PaginationParams) {
    return this.http.get<PagedResult<{FeatureName}>>('/api/{feature-name}', { params });
  }

  getById(id: string) {
    return this.http.get<{FeatureName}>(`/api/{feature-name}/${id}`);
  }

  create(request: Create{FeatureName}Request) {
    return this.http.post<{ id: string }>('/api/{feature-name}', request);
  }
}

Component Pattern

@Component({
  selector: 'app-{feature-name}-list',
  changeDetection: ChangeDetectionStrategy.OnPush,
  imports: [/* only what's needed */],
  template: `
    <!-- Use TanStack Table via EntityListViewComponent for list views -->
    <!-- Use native control flow: @if, @for -->
    <!-- All strings via transloco pipe -->
  `,
})
export class {FeatureName}ListComponent {
  private service = inject({FeatureName}Service);

  items = signal<{FeatureName}[]>([]);
  loading = signal(false);

  totalCount = computed(() => this.items().length);
}

Component Rules

• ChangeDetectionStrategy.OnPush on every component.
• input() / output() functions, not decorators.
• inject() for DI, not constructor.
• Signals + computed() for all state. No BehaviorSubject.
• Native control flow (@if, @for). Never *ngIf, *ngFor.
• Never ngClass/ngStyle. Use class/style bindings.
• All text through Transloco (| transloco).
• Use EntityListViewComponent + TanStack Table for data tables.
• Use Angular Aria for interactive widgets. Angular Material for overlays.

Checklist

• Routes defined and lazy-loaded
• Routes registered in app.routes.ts
• Models defined as TypeScript interfaces
• Service created with inject(HttpClient)
• Components use OnPush, signals, input()/output()
• All user-visible strings use Transloco
• Translation keys added to assets/i18n/en.json and assets/i18n/uk.json
• BFF endpoint exists or is being created alongside
• Accessibility: ARIA attributes, focus management, contrast
