I’m currently following this tuturial: https://www.youtube.com/watch?v=WlAq06Z_25Y&list=PL8p2I9GklV45JZerGMvw5JVxPSxCg8VPv&index=4
but html only shows
i’m trying to learn angular but it’s verry confusing if you try to follow a turturial but some things just dont match up
code:
app.module.ts code:
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'blog';
}
app.component.html code:
<h1>Hello World !</h1>
<h2>{{title}}</h2>
app.component.spec.ts code:
import { TestBed } from '@angular/core/testing';
import { RouterTestingModule } from '@angular/router/testing';
import { AppComponent } from './app.component';
describe('AppComponent', () => {
beforeEach(async () => {
await TestBed.configureTestingModule({
imports: [
RouterTestingModule
],
declarations: [
AppComponent
],
}).compileComponents();
});
it('should create the app', () => {
const fixture = TestBed.createComponent(AppComponent);
const app = fixture.componentInstance;
expect(app).toBeTruthy();
});
it(`should have as title 'blog'`, () => {
const fixture = TestBed.createComponent(AppComponent);
const app = fixture.componentInstance;
expect(app.title).toEqual('blog');
});
it('should render title', () => {
const fixture = TestBed.createComponent(AppComponent);
fixture.detectChanges();
const compiled = fixture.nativeElement;
expect(compiled.querySelector('.content span').textContent).toContain('blog app is running!');
});
});
You need to run your app with
ng serve
and then verify your output onlocalhost:4200
.In case you need to run it on any other port, use
ng serve --port:portnumber
Try creating a public method to pass it between your components:
i used port 5200 but i should use port 4200 instead. now it works
