Creating nested components in Angular enables modular application architecture where child components are embedded within parent components for better code organization. As the creator of CoreUI, a widely used open-source UI library, I’ve built thousands of nested Angular components for enterprise applications with complex component hierarchies. From my expertise, the most effective approach is creating separate child components and embedding them using their selectors in parent templates. This method provides clear separation of concerns, reusable components, and maintainable code structure.
Create child components and embed them in parent templates using component selectors.
// child.component.ts
import { Component, Input } from '@angular/core'
@Component({
selector: 'app-child',
template: `
<div class="child-component">
<h3>{{title}}</h3>
<p>{{message}}</p>
</div>
`
})
export class ChildComponent {
@Input() title = ''
@Input() message = ''
}
// parent.component.ts
@Component({
selector: 'app-parent',
template: `
<div class="parent-component">
<h2>Parent Component</h2>
<app-child
title="First Child"
message="Hello from child 1">
</app-child>
<app-child
title="Second Child"
message="Hello from child 2">
</app-child>
</div>
`
})
export class ParentComponent { }
Generate child components using ng generate component child-name, then embed them in parent templates using their selector tags. Use @Input() decorators to pass data from parent to child components. Angular automatically handles the component lifecycle and rendering hierarchy.
Best Practice Note:
This is the same nested component approach we use in CoreUI Angular components for building complex UI hierarchies. Keep components focused on single responsibilities and use clear naming conventions for better maintainability.
