You have to install redux dev tool chrome extension and react chrome extension.

So , why I need to install these extensions ??It works with these extensions , but the end user won't be having these and why do we need this ?

[seersol92]

just for development purpose. to debug app

[mrgaganchohan]

Sorry , for silly question , but shouldn't the user be able to run the app (website) without extension? I get error without the extension

[seersol92]

you can comment that line simply

[seersol92]

window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__()

any solution? I also have the same issue

I've the same problem but when I try to run my app in Firefox or Safari. But for Chrome the app runs well. I found some insight in this post.

I hope these could be a bit of light for your issues.

a mi me salio porque estaba ejecutando mi proyecto en chrome utilizando redux y "window.REDUX_DEVTOOLS_EXTENSION && window.REDUX_DEVTOOLS_EXTENSION()" al correrlo en firefox u otro navegador saltaba el error. lo solucioné documentando esa linea

[nestornav]

@DanielRobles7 ese error entiendo que si tenés instaladas las dev tools no debería sucederte.

const createStoreWithMiddleware = createStore( rootReducers, compose( applyMiddleware(thunk, logger), window.navigator.userAgent.includes('Chrome') ? window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__() : compose, ), )
