+## 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.
+
+```ts
+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:
+
+```ts
+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(),
+  ],
+};
+```
