Use redux-thunk to handle action sequences.

redux-action-sequences-3.js

import { createStore, applyMiddleware } from 'redux';
import thunk from 'redux-thunk';
import rootReducer from './reducers/index';

// Note: this API requires redux@>=3.1.0
const store = createStore(
  rootReducer,
  applyMiddleware(thunk)
);

// An asynchronous action.
function startRequest() {
  
  // Do somthing before async action starts.
  
  return dispatch => {
    fetch('/api/v1/foo')
      .then(response => response.json())
      .then((data) => {
        dispatch(receive(data));
      })
      .catch((error) => {
        dispatch(showNotification(error));
      });
  }
}

// A normal action.
function showNotification(error) {
  return {
    type: ........
  };
}
