Breaking change
In 2.9.0 we introduced default logger, but this led to problems (#210).
It was so bad that we publish 3 broken versions. So, we decided made a breaking change: by default we now export logger with default options and createLogger is now coming as named import.
TL;DR
You need to change your import
import { applyMiddleware, createStore } from 'redux'
- import createLogger from 'redux-logger'
+ import { createLogger } from 'redux-logger'
// or
- var createLogger = require('redux-logger')
+ var createLogger = require('redux-logger').createLogger
const logger = createLogger()
const store = createStore(
reducer,
applyMiddleware(logger)
)or use logger with default settings
import { applyMiddleware, createStore } from 'redux'
import logger from 'redux-logger'
// or const { logger } = require('redux-logger')
const store = createStore(
reducer,
applyMiddleware(logger)
)
