What is this?

Standalone components declare their own imports and do not need NgModules. Modern Angular apps default to this style.

Why should you care?

Less boilerplate, clearer dependencies per component — better for AngularVerse feature folders.

See it live — copy this example

Run examples in an Angular CLI project (ng serve). Prefer standalone components and TypeScript strict mode.

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

@Component({
  selector: 'app-hello',
  standalone: true,
  imports: [CommonModule],
  template: `<h1>Hello {{ name }}</h1>`,
})
export class HelloComponent {
  name = 'AngularVerse';
}

What happened?

  • standalone: true opts into the modern mode.
  • imports lists other standalone pieces (and NgModules if needed).

Practice next

  1. Generate: ng g c hello --standalone.
  2. Render HelloComponent from the root route.
  3. Add a second binding.
  4. Use @if / @for if your version supports control flow.
  5. Move template to an HTML file.

Remember

Standalone = self-contained component. Import what the template needs. Prefer this for new apps.

Outcome: A standalone component renders on localhost.
