Angular Quickstart

Master the essentials of Angular framework

What is Angular?

Angular is a platform and framework for building single-page client applications using HTML and TypeScript. It implements core and optional functionality as a set of TypeScript libraries that you import into your applications.

TypeScript Component-Based SPA Framework

Core Building Blocks

Components

The basic building blocks of Angular applications:

@Component({
  selector: 'app-root',
  template: `
    
{{title}}

  `
})
export class AppComponent {
  title = 'My App';
}

Services

Reusable business logic and data sharing:

@Injectable({
  providedIn: 'root'
})
export class DataService {
  getData() {
    return ['item1', 'item2'];
  }
}

Modules

Organizing code into cohesive blocks:

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule],
  bootstrap: [AppComponent]
})
export class AppModule { }

Key Concepts

Data Binding

  • Interpolation: {{'{{'}} value {{'}}'}}
  • Property Binding: [property]="value"
  • Event Binding: (event)="handler()"
  • Two-way Binding: [(ngModel)]="value"

Dependency Injection

constructor(private service: DataService) {
  // Service is automatically injected
}

Routing

const routes: Routes = [
  { path: 'home', component: HomeComponent },
  { path: 'about', component: AboutComponent }
];
