HttpClient

Introduction

HttpClient provides a simplified API for HTTP operations with typed responses, interceptors, and error handling.

Setup

bootstrapApplication(AppComponent, {
  providers: [provideHttpClient()]
});

Usage

@Injectable({ providedIn: 'root' })
export class ProductService {
  constructor(private http: HttpClient) {}

  getAll(): Observable<Product[]> {
    return this.http.get<Product[]>('/api/products');
  }

  getById(id: number): Observable<Product> {
    return this.http.get<Product>(`/api/products/${id}`);
  }
}

Summary

HttpClient is essential for API communication in Angular applications.”
