I'm getting an error for <app-entry-list></app-entry-list>

Doctype must be declared first. [Angular] 'app-entry-list' is not a known element:

  1. If 'app-entry-list' is an Angular component, then verify that it is part of this module.
  2. If 'app-entry-list' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.

Hi Mark. Take a look inside your entry-list.component.ts file and see how it compares with this...

entry-list.component.ts

import {Component} from '@angular/core';

@Component({
    selector: 'app-entry-list',
    templateUrl: 'entry-list.component.html',
    styleUrls: ['entry-list.component.css']
})

export class EntryListComponent {

}

...this is where app-entry-list gets defined.
