I have a sample

import * as types from '../../helpers/ActionTypes';

var initialState = {
  changedValues: {}
};
const quickEdit = (state = initialState, action) => {

  switch (action.type) {

    case types.PRODUCT_QUICKEDIT:
      {
        const item = action.item;
        const changedValues = {
          ...state.changedValues,
          [item.id]: item,
        };

        return {
          ...state,
          loading: true,
          changedValues: changedValues,
        };
      }
    default:
      {
        return state;
      }
  }
};

export default quickEdit;
