#[component]
fn App() -> impl IntoView {
    let handle = window_event_listener(ev::keypress, |ev| {
        // ev is typed as KeyboardEvent automatically,
        // so .code() can be called
        let code = ev.code();
        log!("code = {code:?}");
    });
    on_cleanup(move || handle.remove());
