In your Module: 

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

Add `ReactiveFormsModule` to `imports` section.

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': ''
        });
    }
}

In your template: 

<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>
