Common axios.get with timeout in React Native's action creator. This works well at iOS.

export function myActionCreator() {
  return async dispatch => {
    try {
        req = await axios.get(url, {timeout: 4000});
        dispatch ({
            type: ACTION_TYPE,
            payload: req.data,
        })

    } catch (e) {
        dispatch ({
            type: NETWORK_ERROR,
            notice: notice_network_error,
        })
    }
  }
}
