Angular 2+ - on input change

How to listen input change on every keypress in Angular 2+ ? 

Well it is very simple, we just have to call method on (input):

                    <input matInput type="text" (input)="onChange($event)">

                  

and then in your component create that function and listen for event.target.value:

                    onChange(event): void{
  console.log(event.target.value)
}
