Solution
You don't have AppComponent. In the app.component.ts you PostComponent where class AppComponent you specify in NgModule?
and yet you have no post/post.component.ts where you have to lie PostsComponent , he you have in the app.component.ts - maverick.Romaguera commented on June 14th 19 at 21:09
