Is there a way to extract information from an HttpClient Rest Api through interpolation?

I am currently facing an issue with a component in my project. The component is responsible for fetching data from a REST API using the HttpClient, and the data retrieval seems to be working fine as I can see the data being logged in the Console.

However, I am encountering difficulties when it comes to displaying this data in the HTML. Despite no errors in the code, the data simply refuses to show up on the screen.

Below is a snippet of the relevant code:

Imports within the Component

    import { Component, OnInit } from '@angular/core';
    import {MatTabsModule} from '@angular/material/tabs';
    import {MatListModule} from '@angular/material/list'; 
    import { Observable } from 'rxjs';
    import {HttpClient, HttpHeaders} from '@angular/common/http';

This is the class definition

    export class TestComponent implements OnInit {
    constructor(private http: HttpClient ) {
    
    this.http
    .get<any>('http://api.data_redacted_for_privacy').subscribe(data => {
    console.log(data);
    });
    }

    ngOnInit(){

    this.http
    .get<any>('http://api.data_redacted_for_privacy').subscribe(data => {
    console.log(data;
    });

    }
    }

The HTML code attempts to display the data like so:

<div *ngFor="let data">{{data.id}}</div>

I have also experimented with using an Observable but I suspect that my implementation may be incorrect. It seems quite different from working with AngularFire.

Answer №1

Store the retrieved information in a class variable and iterate through it using let... of...:

export class TestComponent implements OnInit {

   allData: any = null; // or any other type available

   constructor(private http: HttpClient){} 

   ngOnInit(){

       this.http.get<any>('http://api.data_redacted_for_privacy').subscribe(data => {
          console.log(data);
          this.allData = data;
        });
    }

}

Then in template:

<div *ngFor="let data of allData">{{data.id}}</div>
