Typescript: React event types

Question

What is the correct type for React events. Initially I just used any for the sake of simplicity. Now, I am trying to clean things up and avoid use of any<

Answer 1

I think the simplest way is that:

type InputEvent = React.ChangeEvent;
type ButtonEvent = React.MouseEvent;

update = (e: InputEvent): void => this.props.login[e.target.name] = e.target.value;
submit = (e:  ButtonEvent): void => {
    this.props.login.logIn();
    e.preventDefault();
}
