How to add multiple middleware to Redux?

Question

I have one piece of middleware already plugged in, redux-thunk, and I'd like to add another, redux-logger.

How do I configure it so my app uses both pieces of middleware? I tried passing in an array of [ReduxThunk, logger] but that didn't work.

Code:

import React from 'react';
import ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import { createStore, applyMiddleware } from 'redux';
import ReduxThunk from 'redux-thunk';
import logger from 'redux-logger';

import App from './components/app';
import reducers from './reducers';
require('./style.scss');

const createStoreWithMiddleware = applyMiddleware(ReduxThunk)(createStore);

ReactDOM.render(
  <Provider store={createStoreWithMiddleware(reducers)}>
    <App />
  </Provider>,
  document.querySelector('#app')
);

Answer 1

applyMiddleware takes each piece of middleware as a new argument (not an array). So just pass in each piece of middleware you'd like.

const createStoreWithMiddleware = applyMiddleware(ReduxThunk, logger)(createStore);

Answer 2

answer of andy's is good, but, consider your middlewares growing, below codes will be better:

const middlewares = [ReduxThunk, logger]
applyMiddleware(...middlewares)

Answer 3

applyMiddleware should pass into createStore as the second parameter. applyMiddleware can have multiple middlewares as arguments.

const store = createStore(reducers, applyMiddleware(ReduxThunk, logger));

ReactDOM.render(
  <Provider store={store}>
    <App />
  </Provider>,
  document.querySelector('#app')
);
