Скачать или смотреть Can't bind to 'FormGroup' since it isn't a known property of 'form'

i have created new project using
ng new angularTutorial command (typed in command prompt)
in this project only 1 component is there which is root component(or app.component.ts)

now run project using ng serve command & press enter & wait for run (√ Compiled
successfully.)
after check output on browser & type localhost:4200 on the URL & press enter

lets add formgroup & formcontrol in the app.component.ts

import { FormGroup,FormControl } from '@angular/forms';

userForm : FormGroup;

ngOnInit()
{
this.userForm = new FormGroup({
username : new FormControl(),
email : new FormControl()
});
}


my html (app.component.html) code is ready so
lets add formGroup property to form tag as
[formGroup]="userForm"
AND
formControlName property to input tag as
formControlName="username" for input username
formControlName="email" for input useremail

Can't bind to 'FormGroup' since it isn't a known property of 'form'.

to solve this issue add ReactiveFormsModule to the app.module.ts
and also add it in imports array

here is your issue solved
