suggestion: add info about dispatched action types

const actions = {
  ping: createAction('ping/PING', (arg: number) => ({
    type: 'ping/PING',
    arg,
  })),
};

interface Props {
  ping: typeof actions.ping;
}

const PingTestComponent: React.SFC<Props> = ({ping}) => {
  return (
    <Button onPress={() => ping(123)} title="ping"/>
  );
};

export const PingTest = connect(
  null,
  ({ ping: actions.ping })
)(PingTestComponent);
