HTTP Client Module

The HttpClientModule is used to make HTTP requests to a server in an Angular application. It provides services for making GET, POST, PUT, DELETE, and other types of requests.

import { HttpClientModule } from '@angular/common/http';

@NgModule({
  imports: [HttpClientModule],
})

export class AppModule {}

In the angular v17 and above, the HttpClientModule has been deprecated. Instead, you can use the provideHttpClient function to provide the HttpClient service in your application. Here is an example of how to use the provideHttpClient function to provide the HttpClient service in your application:

import { ApplicationConfig, provideZoneChangeDetection } from '@angular/core';
import { provideRouter } from '@angular/router';

import { routes } from './app.routes';
import { provideHttpClient } from '@angular/common/http';

export const appConfig: ApplicationConfig = {
  providers: [
    provideZoneChangeDetection({ eventCoalescing: true }),
    provideRouter(routes),
    provideHttpClient(),
  ],
};
