devs don't know you can extract response headers with #Angular's HttpClient You just need to observe the entire response. not just the body: Provide example it

 To extract response headers with Angular's HttpClient, you can observe the full response using the observe: 'response' option. Here's an example:

typescript

import { HttpClient } from '@angular/common/http';
import { Injectable } from '@angular/core';
import { Observable } from 'rxjs';

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

  getData(): Observable<any> {
    return this.http.get('https://example.com/api/data', { observe: 'response' });
  }
}

In the component, you can then access both the body and headers:

typescript

import { Component, OnInit } from '@angular/core';
import { ApiService } from './api.service';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponent implements OnInit {
  constructor(private apiService: ApiService) {}

  ngOnInit() {
    this.apiService.getData().subscribe(response => {
      console.log('Response Body:', response.body);
      console.log('Response Headers:', response.headers);
    });
  }
}

In this case, response.body will give you the data, while response.headers will give you the headers.
