How to correctly import FormGroup in NgModule in Angular 2

Question

I try to import FromGroup, FormBuilder and FormControl to my CustomModule:

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

@NgModule({
  imports: [
    FormsModule,
    FormGroup
  ]
})

But it throws an error:

EXCEPTION: Uncaught (in promise): Error: Unexpected value 'FormGroup' imported by the module 'CustomModule'

If i only import FormsModule it works fine though.

Any ideas?

You can't add FormGroup to module's imports, just import it in the component in which you want to use FormGroup. You can only add MODULES to module's imports. Also, if you want to use FormGroup directive, you will need to import ReactiveFormsModule in your module:

@NgModule({
  imports: [
    FormsModule,
    ReactiveFormsModule
  ]
})
