Angular forms FormControlDirective

In this article, we are going to see what is FormControlDirective in Angular 10 and how to use it.

The FormControlDirective is used to synchronize a standalone FormControl instance to a form control element

<form [FormControlDirective] ="name">

Exported from:

• ReactiveFormsModule

Selectors:

• [FormControl]

Approach: 

• Create the Angular app to be used
• In app.component.ts make an object that contains a value for the input.
• In app.component.html use FormControlDirective to get values.
• Serve the angular app using ng serve to see the output.

Example:

app.component.ts

import { Component, Inject } from '@angular/core';
  import { FormGroup, FormControl, FormArray } from '@angular/forms'
  @Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: [ './app.component.css' ]
  })
  export class AppComponent  {
    geek: FormControl = new FormControl('');
  }

app.component.html

<br>
<input [formControl]="geek">


<p>Value: {{ geek.value }}</p>
