In Angular app, If you want to use two-way data binding for template driven form inputs, we need to import the FormsModule from @angular/core in app.module.ts.

In order to be able to use two-way data binding for form inputs you need to import the FormsModule package in your Angular module as shown in code below.

app.module.ts


import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms'; 
import { ReactiveFormsModule } from '@angular/forms';

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

And if you are using Reactive Form(FormBuilder class) then you will need to import ReactiveFormsModule as well as shown in above code.
