Components
~ $ ng generate component app
export class AppComponent { title = 'app works!'; } import
{ Component } from '@angular/core'; @Component({ selector: 'app-root', template: `<h1>{{title}}</h1>`, styleUrls: ['./app.component.css'] })
export class AppComponent { title = 'app works!'; } import

export class AppComponent { title = 'app works!'; } @Component({
selector: 'app-root', template: `<h1>{{title}}</h1>`, styleUrls: ['./app.component.css'] }) import { Component } from '@angular/core';
Data binding
http://jsbin.com/hayiyuyeve/edit?html,js,output
@Component({ selector: 'my-greeting', template: ` <input type="text" [(ngModel)]="hero.name"> <h2>Hello, {{hero.name}}</h2>
`, }) export class Greeting { constructor() { this.hero = { name: 'Ciro' } } } http://plnkr.co/edit/MGnF3Ta5IOPYYAyXjFpl?p=preview
Binding Example Properties <fy-rating [rating]="feedback.rating"> Events <fy-rating (onRate)="feedback.update($event)"> Two-way <input
type="text" [(ngModel)]="user.name">
Services
~ $ ng generate service feedback
@Injectable() export class FeedbackService { constructor() { } }
@Injectable() export class FeedbackService { private feedbacksUrl = 'http://localhost:4222/feedbacks'; constructor(private
http: Http) { } getFeedbacks(): Observable<Feedback[]> { return this.http.get(this.feedbacksUrl) .map(this.extractData); } }
Dependency Injection
@Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'], providers: [FeedbackService] })
export class AppComponent implements OnInit { feedbacks: Feedback[]; constructor(private feedbackService: FeedbackService) {} ngOnInit() { this.feedbackService.getFeedbacks() .subscribe(feedbacks => this.feedbacks = feedbacks); } }
@Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'], providers: [FeedbackService] })
export class AppComponent implements OnInit { feedbacks: Feedback[]; constructor(private feedbackService: FeedbackService) {} ngOnInit() { this.feedbackService.getFeedbacks() .subscribe(feedbacks => this.feedbacks = feedbacks); } }
Directives
~ $ ng generate directive highlight
@Directive({ selector: '[myHighlight]' }) export class HighlightDirective { constructor(el: ElementRef,
renderer: Renderer) { renderer.setElementStyle(el.nativeElement, 'backgroundColor', 'yellow'); } }
@Directive({ selector: '[myHighlight]' }) export class HighlightDirective { constructor(el: ElementRef,
renderer: Renderer) { renderer.setElementStyle(el.nativeElement, 'backgroundColor', 'yellow'); } }
Pipes
@Component({ selector: 'hero-birthday', template: `<p>The hero's birthday is {{ birthday
| date }}</p>` }) export class HeroBirthdayComponent { birthday = new Date(1988, 3, 15); // April 15, 1988 }
