A reactive form

import { Component } from '@angular/core';
import { FormGroup, FormControl, Validators, ReactiveFormsModule } from '@angular/forms';

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [ReactiveFormsModule],
  template: `
    <form [formGroup]="form" (ngSubmit)="submit()">
      <input formControlName="email" placeholder="email" />
      <button [disabled]="form.invalid">Save</button>
    </form>
  `,
})
export class AppComponent {
  form = new FormGroup({
    email: new FormControl('', [Validators.required, Validators.email]),
  });
  submit() { console.log(this.form.value); }  // synchronous value access
}
