How to add multiple middleware to Redux?
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 of andy's is good,but, consider your middlewares growing,below codes will be better:
const middlewares = [ReduxThunk, logger]applyMiddleware(...middlewares)
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'));
