Model Driven Forms (Reactive forms) in Angular2

Model Driven Forms (Reactive forms) in Angular2

1) In your Module:

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

Add `ReactiveFormsModule` to `imports` section.

2) In your Component:

import { FormGroup, FormControl } from '@angular/forms';
 
export class MyComponent {
    myForm: FormGroup;
 
    constructor() {
        this.myForm = new FormGroup({
            field1: new FormControl(),
            field2: new FormControl()
        });
    }
}

or

import { FormGroup, FormBuilder } from '@angular/forms';
 
export class MyComponent {
    myForm: FormGroup;
 
    constructor(private fb: FormBuilder) {
        this.myForm = fb.group({
            'field1': '',
            'field2': ''
        });
    }
}

3) In your template:

These are similar to ngModel of Angular1:

<form [formGroup]="myForm">
    <input type="text" formControlName="field1" />
    <input type="text" formControlName="field2" />
</form>

or

<form [formGroup]="myForm">
    <input type="text" [formControl]="myForm.controls['field1']" />
    <input type="text" [formControl]="myForm.controls['field2']" />
</form>
