Why should you care?

Almost every screen is a composition of these fundamentals.

See it live — copy this example

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

@Component({
  standalone: true,
  selector: 'app-demo',
  template: `<!-- Dependency Injection Basics -->`,
})
export class DemoComponent {}

What happened?

• Start from a standalone component and add only what the topic needs.
• Follow the steps below — typing the code yourself is the fastest way to learn.

Practice next

1. Reproduce the snippet in an Angular CLI app.
2. Change one binding or route and re-serve.
3. Note one mistake you almost made.
4. Extract a service.
5. Add a trivial unit test later.

Remember

You can explain Dependency Injection Basics simply. You ran a small Angular demo. You know one pitfall.

Your team applies dependency injection basics on an admin UI.
