You are currently using minified code outside of NODE_ENV === "production".

When I use redux-starter-kit with webpack in production mode, keep telling me this:
This means that you are running a slower development build of Redux. You can use loose-envify (https://github.com/zertosh/loose-envify) for browserify or setting mode to production in webpack (https://webpack.js.org/concepts/mode/) to ensure you have the correct code for your production build.

I didn't find any file names like "*.min.js" under /node_modules/redux-starter-kit/dist/

Hmm. It's possible we have our lib build settings wrong.

Can you create a small project that reproduces the issue?

[OrzX]

$ create-react-app hello-redux
$ cd hello-redux
$ npm install --save redux-starter-kit

then add the code blew in /src/index.js

import { getDefaultMiddleware } from 'redux-starter-kit';
// make sure the lib is imported.
const defaultMiddleware = getDefaultMiddleware();

$ npm run build

No we can see the warning message:

$ npm install -g serve
$ serve -s build

open http://localhost:5000/, the warning message should be displayed in the console output

Hmm. Looking at the sourcemap, it kinda seems like it's maybe using the UMD build instead of the CommonJS or ESM builds.

Our package.json currently says:

  "main": "dist/redux-starter-kit.cjs.js",
  "module": "dist/redux-starter-kit.esm.js",
  "browser": "dist/redux-starter-kit.umd.js",

I don't know enough about those fields to understand the differences.

[markerikson]

Aha. This look like it's sort of a dupe of #55 .

This should be resolved in https://github.com/reduxjs/redux-starter-kit/releases/tag/v0.3.2 .
