Code example

index.js

import React from 'react';
import ReactDom from 'react-dom';
import { Provider } from 'react-redux';
import {
  // BrowserRouter as Router,
  Route,
} from 'react-router-dom';
import createHistory from 'history/createBrowserHistory';
import { ConnectedRouter } from 'react-router-redux';

// Styles
import 'sanitize.css/sanitize.css';
import './global-styles';

import configureStore from './store';
import rootSaga from './rootSaga';
import App from 'containers/App';


const rootElement = document.getElementById('root');
const initialState = {};
const history = createHistory();
const store = configureStore(initialState, history);

// Run rootSaga
store.runSaga(rootSaga);

ReactDom.render(
  <Provider store={store}>
    <ConnectedRouter history={history}>
      <Route path="/" component={App} />
    </ConnectedRouter>
  </Provider>,
  rootElement
);

store.js

import { createStore, combineReducers, applyMiddleware, compose } from 'redux';
import createSagaMiddleWare from 'redux-saga';
import promise from 'redux-promise';
import { routerMiddleware } from 'react-router-redux';

import rootReducer from './rootReducer';


export default function configureStore(initialState, history) {
  const sagaMiddleWare = createSagaMiddleWare();
  const routerMW = routerMiddleware(history);
  const middleWares = [
    routerMW,
    promise,
    sagaMiddleWare,
  ];

  const enhancers = [
    applyMiddleware(...middleWares)
  ];

  const composeEnhancers =
    process.env.NODE_ENV !== 'production' &&
    typeof window === 'object' &&
    window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ ?
      window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ : compose;

  const store = createStore(
    rootReducer,
    initialState,
    composeEnhancers(...enhancers),
  );

  store.runSaga = sagaMiddleWare.run;

  return store;
}
