Generate Service Proxies

abp generate-proxy -t ng

This generates typed service classes in src/app/proxy/.

List Component Pattern

@Component({
  selector: 'app-book-list',
  templateUrl: './book-list.component.html'
})
export class BookListComponent implements OnInit {
  books = { items: [], totalCount: 0 } as PagedResultDto<BookDto>;

  constructor(
    public readonly list: ListService,
    private bookService: BookService,
    private confirmation: ConfirmationService
  ) {}

  ngOnInit(): void {
    this.hookToQuery();
  }

  private hookToQuery(): void {
    this.list.hookToQuery(query =>
      this.bookService.getList(query)
    ).subscribe(response => {
      this.books = response;
    });
  }

  create(): void {
    // Open create modal
  }

  delete(book: BookDto): void {
    this.confirmation
      .warn('::AreYouSureToDelete', '::AreYouSure')
      .subscribe(status => {
        if (status === Confirmation.Status.confirm) {
          this.bookService.delete(book.id).subscribe(() => this.list.get());
        }
      });
  }
}

Localization

// In component
constructor(private localizationService: LocalizationService) {}

getText(): string {
  return this.localizationService.instant('::Books');
}

<!-- In template -->
<h1>{{ '::Books' | abpLocalization }}</h1>

<!-- With parameters -->
<p>{{ '::WelcomeMessage' | abpLocalization: userName }}</p>

Authorization

Permission Directive

<button *abpPermission="'BookStore.Books.Create'">Create</button>

Permission Guard

const routes: Routes = [
  {
    path: '',
    component: BookListComponent,
    canActivate: [PermissionGuard],
    data: {
      requiredPolicy: 'BookStore.Books'
    }
  }
];

Programmatic Check

constructor(private permissionService: PermissionService) {}

canCreate(): boolean {
  return this.permissionService.getGrantedPolicy('BookStore.Books.Create');
}

Forms with Validation

@Component({...})
export class BookFormComponent {
  form: FormGroup;

  constructor(private fb: FormBuilder) {
    this.buildForm();
  }

  buildForm(): void {
    this.form = this.fb.group({
      name: ['', [Validators.required, Validators.maxLength(128)]],
      price: [0, [Validators.required, Validators.min(0)]]
    });
  }

  save(): void {
    if (this.form.invalid) return;

    this.bookService.create(this.form.value).subscribe(() => {
      // Handle success
    });
  }
}

<form [formGroup]="form" (ngSubmit)="save()">
  <div class="form-group">
    <label for="name">{{ '::Name' | abpLocalization }}</label>
    <input type="text" id="name" formControlName="name" class="form-control" />
  </div>

  <button type="submit" class="btn btn-primary" [disabled]="form.invalid">
    {{ '::Save' | abpLocalization }}
  </button>
</form>

Configuration API

constructor(private configService: ConfigStateService) {}

getCurrentUser(): CurrentUserDto {
  return this.configService.getOne('currentUser');
}

getSettings(): void {
  const setting = this.configService.getSetting('MyApp.MaxItemCount');
}

Modal Service

constructor(private modalService: ModalService) {}

openCreateModal(): void {
  const modalRef = this.modalService.open(BookFormComponent, {
    size: 'lg'
  });

  modalRef.result.then(result => {
    if (result) {
      this.list.get();
    }
  });
}

Toast Notifications

constructor(private toaster: ToasterService) {}

showSuccess(): void {
  this.toaster.success('::BookCreatedSuccessfully', '::Success');
}

showError(error: string): void {
  this.toaster.error(error, '::Error');
}

Lazy Loading Modules

// app-routing.module.ts
const routes: Routes = [
  {
    path: 'books',
    loadChildren: () => import('./book/book.module').then(m => m.BookModule)
  }
];

Theme & Styling

• Use Bootstrap classes
• ABP provides theme variables via CSS custom properties
• Component-specific styles in .component.scss
