@NgModule({

imports: [ BrowserModule, FormsModule ],

declarations: [ AppComponent],

bootstrap: [ AppComponent ]

})

export class AppModule { }

src/app/app.component.ts

import { Component } from '@angular/core';

import {NgForm} from '@angular/forms';

@Component({

selector: 'my-app',

templateUrl: './app.component.html',

styleUrls: [ './app.component.css' ]

})

export class AppComponent {

onSubmit(myForm: NgForm) {

console.log(myForm.value);

console.log(myForm.valid);

}
