A component is a building block of an Angular application that controls a portion of the view through its template and class. It's composed by a template, a class and metadata. To call a component in Angular, you need to use it as a directive within the template of another component. Components can be nested, meaning that a component can include other components within its template. This allows for the building of complex user interfaces by composing smaller, reusable components.
The following example will explain that a component called cstm-component with the selector app-cstm-component, you can include it in another component's template like this:
<!-- other-component.component.html -->
<div>
<app-my-component></app-my-component>
</div>
We need to make sure that the component that you are calling is declared in the declarations array of the @NgModule decorator of the module where it is being used.
@NgModule({
declarations: [MyComponent, OtherComponent],
imports: [],
providers: [],
bootstrap: [OtherComponent]
})
export class MyModule { }
