What is the best way to dynamically load application components based on incoming data?

I am working on an Angular project where I need to dynamically load different components based on API data. The home page consists of a banner and a news section. Instead of having the banner always at the top and the news section at the bottom, I want to load these components multiple times with different data based on what is fetched from the database.

In the home.component.ts file, I have the following code:

import { Component, OnInit, ViewEncapsulation } from '@angular/core';
import { AccountServiceProvider} from '../../providers/account-service/account-service';

@Component({
    selector      : 'app-home',
    templateUrl   : './home.component.html',
    styleUrls     : ['./home.component.scss'],
    encapsulation : ViewEncapsulation.None
})
export class HomeComponent implements OnInit {

    public banner           : any;
    public news             : any;

    constructor( private accountService : AccountServiceProvider ) {
        /* Data is fetched from WordPress API; client can choose either banner first or news first */
        this.accountService.getStartPageData().then( ( response: any ) => {
            for ( let entry of response ) {
                if ( 'banner_block' === entry.acf_fc_layout ) {
                    this.banner = entry;
                }
                if ( 'news_block' === entry.acf_fc_layout ) {
                    this.news = entry;
                }
            }
        });
    }

    ngOnInit() {
    }
}

The home.component.html, banner.component.ts, and news.component.ts files contain the template and logic for loading the banner and news components dynamically according to the data received.

Instead of statically adding these components, I want to dynamically load them based on the data. I am currently researching solutions on how to achieve this, including the possibility of loading component HTML in the component TypeScript file. However, I have not yet found a definitive answer.

To implement conditional rendering, you can utilize the ngIf directive like so:

<div *ngIf="condition; then displayBanner else displayNews"></div>
<ng-template #displayBanner><app-banner [bannerData]="banner"></app-banner></ng-template>
<ng-template #displayNews><app-news [newsData]="news"></app-news></ng-template>

For more information, you can refer to the documentation here
