    <input [(ngModel)]="name" placeholder="Enter your name">
    <p>Hello, {{ name }}!</p>
  `,
})
export class AppComponent {
  name = '';
}

Using Angular Services

Services are used to share data or logic between different components.

// data.service.ts
import { Injectable } from '@angular/core';

@Injectable({
providedIn: 'root'
})
export class DataService {
getMessage() {
return 'This is data from a service!';
}
}

// app.component.ts
import { Component, OnInit } from '@angular/core';
import { DataService } from './data.service';

@Component({
selector: 'app-root',
template: `<p>{{ message }}</p>`
})
export class AppComponent implements OnInit {
message: string = '';

constructor(private dataService: DataService) {}

ngOnInit() {
this.message = this.dataService.getMessage();
}
}

Using ngFor for List Rendering

The *ngFor directive is used to iterate over a list.

// app.component.ts
import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  template: `
    <ul>
      <li *ngFor="let item of items">{{ item }}</li>
    </ul>
  `,
})
export class AppComponent {
  items = ['Apple', 'Banana', 'Cherry'];
}

Reactive Forms Example

Reactive forms allow you to handle form inputs with more control.

// app.component.ts
import { Component } from '@angular/core';
import { FormGroup, FormBuilder, Validators } from '@angular/forms';

@Component({
  selector: 'app-root',
  template: `
    <form [formGroup]="form" (ngSubmit)="onSubmit()">
      <label for="email">Email:</label>
      <input id="email" formControlName="email">
      <div *ngIf="form.get('email')?.invalid && form.get('email')?.touched">
        Email is required and must be valid.
      </div>
      <button type="submit" [disabled]="form.invalid">Submit</button>
    </form>
  `,
})
export class AppComponent {
  form: FormGroup;

  constructor(private fb: FormBuilder) {
    this.form = this.fb.group({
      email: ['', [Validators.required, Validators.email]],
    });
  }

  onSubmit() {
    console.log(this.form.value);
  }
}

Custom Directive Example

Directives are used to manipulate the DOM.

// highlight.directive.ts
import { Directive, ElementRef, HostListener } from '@angular/core';

@Directive({

})
export class HighlightDirective {
constructor(private el: ElementRef) {}

@HostListener('mouseenter') onMouseEnter() {
this.el.nativeElement.style.backgroundColor = 'yellow';
}

@HostListener('mouseleave') onMouseLeave() {
this.el.nativeElement.style.backgroundColor = null;
}
}

// app.component.html
<p appHighlight>Hover over this text to see the highlight effect.</p>

HTTP Request Example

Use Angular’s HttpClient to fetch data from an API.

// data.service.ts
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Injectable({
  providedIn: 'root'
})
export class DataService {
  constructor(private http: HttpClient) {}

  fetchData() {
    return this.http.get('https://jsonplaceholder.typicode.com/posts');
  }
}

// app.component.ts
import { Component, OnInit } from '@angular/core';
import { DataService } from './data.service';

@Component({
  selector: 'app-root',
  template: `
    <ul>
      <li *ngFor="let post of posts">{{ post.title }}</li>
    </ul>
  `,
})
export class AppComponent implements OnInit {
  posts: any[] = [];

  constructor(private dataService: DataService) {}
