// Dependency : http://redux.js.org/ 

import { createStore, applyMiddleware } from 'redux';

import promise from 'redux-promise';
import logger from 'redux-logger';

const configureStore = () => {
  // creating array of middleware
  const middlewares = [promise];
  middlewares.push(logger);
  const store = createStore(todoApp, applyMiddleware(...middlewares)); // spreading middlewares as individual argument
  return store;
}

export default configureStore;
