Passing State to Action Creators

In the case where you need to read state in an action creator what is the best way to do so… For example suppose I have an action creator that gets a new user object:

export function load(state) {
  return (dispatch) => {
    if (getUser(state)) return null;

    get()
      .then((response) => {
        dispatch({
          type: AppConstants.USER_LOAD_SUCCESS,
          payload: {
            response
          }
        });
      });
  }
} 

Notice it is configured ahead of time with the current state, this enables the action creator to decide if it should really fire the action or not. Currently the mapping state and actions to components is separated, what do you do when an action creator needs access to state?

export default connect((state, props) => {
  return {
    user: getUser(state)
  };
}, (dispatch) => {
  // I want state here to configure my action creator!
  return {
    load: () => dispatch(load(state))
  }
})(User);

export function load() {
  return (dispatch, getState) => {
    const state = getState()
    if (getUser(state)) return null;

    get()
      .then((response) => {
        dispatch({
          type: AppConstants.USER_LOAD_SUCCESS,
          payload: {
            response
          }
        });
      });
  }
} 

is not the second parameter provided when using redux-thunk the getState function?

@tomascharad : I believe Redux-Saga provides a select() operation, which you would use roughly like:

const allTheState = yield select(state => state);
const oneSmallPieceOfState = yield select(someSpecificSelectorFunction);
