Warning in production build that I use development build.

[bukowskiadam]

Hi there,

I get this warning from redux introduced in reduxjs/redux#1075 on my app with production build.

I've included redux-mock-store by accident in production build. It seems that during your build process for es module you replace NODE_ENV to development which gets replaced in included redux.

Steps to reproduce

1. build redux-mock-store with npm run build:es
2. peek into file dist/index-es.js, line 205:

if ("development" !== 'production' && typeof isCrushed.name === 'string' && isCrushed.name !== 'isCrushed') {

When I include redux-mock-store, then in production build it always gives this warning.

Solution

Probably you should not replace NODE_ENV for es module like redux does this.
