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.

How do you test Angular components? ● Use Angular’s TestBed to create a testing module that declares the component. ● Instantiate the component and its template for testing. ● Test component logic, DOM rendering, event handling, and bindings. ● Use Angular testing utilities like fixture.detectChanges() to update the view. Basic example: beforeEach(async () => {
wait TestBed.configureTestingModule({ declarations: [MyComponent] }).compileComponents(); fixture = TestBed.createComponent(MyComponent); component = fixture.componentInstance; fixture.detectChanges(); }); it('should cre…

How do you structure Angular projects for scalability? ● Feature-based folder structure: Organize by features rather than by type. /src/app /products /components /services /models products.module.ts /orders /shared /core ● Core module: For singleton services used app-wide (e.g., authentication, logging). ● Shared module: For shared components, pipes, and directives reused across the
Answer: pp. Lazy load feature modules: Load modules on demand to improve startup time. Use state management (e.g., NgRx) when app state becomes complex. Adopt consistent routing with child routes. What interviewers expec…
