Dan Parker - Medium article

yarn install reselect
copy

// Reducer file
import { createSelector } from "reselect";

/* Creating the Selector in reducer file */
const getElementsUi = (state) => state.sidebarReducer.elementsUi;

export const getElementsUiState = createSelector(
  [getElementsUi],
  (elementsUi) => elementsUi
);

// In file calling mapStateToProps
const mapStateToProps = (state) => ({
  elementsUi: reducers.getElementsUiState(state),
});

const mapDispatchToProps = (dispatch) => ({ dispatch: dispatch });

export default connect(mapStateToProps, mapDispatchToProps)(Component);
copy
