Redux-logger export changed


I have upgraded my webpack to the latest version.
After fixing some issue with my webpack.config I can compile again.
But now I am seeing the following errors when I am trying to run my site:

[redux-logger v3] BREAKING CHANGE
[redux-logger v3] Since 3.0.0 redux-logger exports by default logger with default settings.
[redux-logger v3] Change
[redux-logger v3] import createLogger from 'redux-logger'
[redux-logger v3] to
[redux-logger v3] import { createLogger } from 'redux-logger'

Uncaught TypeError: middleware is not a function
at applyMiddleware.js:39
at (<anonymous>)
at applyMiddleware.js:38
at createStore (createStore.js:51)
at configureStore (store.js:13)
at Object.<anonymous> (NavBar.js:7)
at Object.module.exports (bundle-hot.js:106583)
at __webpack_require__ (bootstrap 876f8fb1506d9b4ca875:707)
at fn (bootstrap 876f8fb1506d9b4ca875:112)
at Object.<anonymous> (App.js:6)

I went to the npm page for redu-logger and the example is still with the old format.
Yet the doc page shows the changes.

This is my current store.js

import { applyMiddleware, compose, createStore } from 'redux';

import { thunk } from 'redux-thunk';
import { logger } from "redux-logger"
import { browserHistory } from 'react-router';
import { routerMiddleware } from 'react-router-redux';

import reducer from '../reducers';

const middleware = applyMiddleware(thunk, logger({collapsed:true}),     routerMiddleware(browserHistory));

export default function configureStore(initialState) {
const store = createStore(
    compose (
        window.devToolsExtension ? window.devToolsExtension() : f => f

    if ( {
        // Enable Webpack hot module replacement for reducers'../reducers', () => {
            const nextRootReducer = require('../reducers').default;

return store;

The versions I am using:

"redux": "3.7.2"
"redux-thunk": "2.2.0",
"redux-logger": "3.0.6",
"react-router": "4.2.0",
"react-router-redux": "4.0.8",

Update #1

Following the answer of @Alechill I now get the following issue (which I believe is related):

sync.js:104 Uncaught TypeError: Cannot read property 'listen' of undefined
at syncHistoryWithStore (sync.js:104)
at Object.<anonymous> (NavBar.js:8)
at Object.module.exports (bundle-hot.js:106587)
at __webpack_require__ (bootstrap 1b638ac8e0fc25802b6f:707)
at fn (bootstrap 1b638ac8e0fc25802b6f:112)
at Object.<anonymous> (App.js:6)
at Object.<anonymous> (bundle-hot.js:66975)
at __webpack_require__ (bootstrap 1b638ac8e0fc25802b6f:707)
at fn (bootstrap 1b638ac8e0fc25802b6f:112)
at Object.<anonymous> (index-hot.js:9)

This is my NavBar.js top lines:

import React from 'react';
import { connect } from 'react-redux';
import { bindActionCreators } from 'redux';
import { browserHistory } from 'react-router';
import { syncHistoryWithStore } from 'react-router-redux';
import configureStore from '../store/store';
const store = configureStore();
const history = syncHistoryWithStore(browserHistory, store);

The error comes from syncHistoryWithStore wich uses the store.

This was working before I upgraded to the latest version of webpack and all the dependencies.
Could it be that it is called too soon?




You are importing logger but should instead import createLogger since the exports have changed

From the type defs:

export const logger: Redux.Middleware;
export function createLogger(options?: ReduxLoggerOptions): Redux.Middleware;

the logger you are importing is just a default instance of the middleware, but you are trying to call it as if it were the factory function

You can fix that in your module by:

import { createLogger } from 'redux-logger'
const middleware = applyMiddleware(thunk, createLogger({collapsed:true}), routerMiddleware(browserHistory))


Thanks, I am updating my question with what is happening now.
