it should iterate single serverElements by <app-server-element *ngFor>. But it isnt doing,although the course which i am folowing(Maximilian Schwarzmuller) code works fine.. Help
you missed the assignment of serverElements. It should have some value, you just declare the type.
app.component.ts
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
// assign the value, you declare it as type but it was emplty
serverElements = [
{ type: "blueprint", name: "abnc", content: "Just A Test" }
];
}
