HTTP Client in Angular

This lesson covers using Angular's HTTP Client to communicate with APIs, allowing you to fetch and send data easily.

What is HTTP Client?

The HTTP Client is Angular's built-in module for communicating with backend services through HTTP requests.

Importing HttpClientModule

Import HttpClientModule in your application module to start using HTTP requests:

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

Making a GET Request

Use the HTTP client to fetch data from an API endpoint:

this.http.get('https://api.example.com/data').subscribe(data => console.log(data));

Handling Response Data

The HTTP client returns Observables. Subscribe to these to handle data asynchronously:

this.http.get('api/data').subscribe(response => this.data = response);

POST Request to Send Data

Send data to the server using a POST request:

this.http.post('api/items', newItem).subscribe(result => console.log(result));

Error Handling

Handle errors from HTTP requests using the catchError operator:

this.http.get('api/data').pipe(catchError(error => of('Error occurred'))).subscribe();

Using Headers

Add headers to HTTP requests to send additional information:

const headers = new HttpHeaders().set('Authorization', 'my-auth-token');
