Minified code outside of NODE_ENV === 'production'. This means slower development build of Redux
<p>So this is the full error: 
<strong>You are currently using minified code outside of NODE_ENV === 'production'. This means that you are running a slower development build of Redux.</strong></p>

<p>I am using a 3rd party charting library, CanvasJS, which needs access to the global scope. When I import it within any of my modules it seems the actual code breaks when in the browser (probably a <code>this</code> problem). </p>

<p>I solved it by using Webpack, and having gulp bundle the bundle.min.js with the minified Charting library. </p>

<p>This works just fine until I try a production build. I think the reference to <strong>CanvasJS</strong> may have gotten mangled in the process.</p>

<p>My Webpack.config file: </p>

<pre><code> var debug = process.env.NODE_ENV !== "production";
 var webpack = require('webpack');
 var path = require('path');

 module.exports = {
  context: path.join(__dirname, "public"),
  devtool: debug ? "inline-sourcemap" : null,
  entry: "./js/main.js",
  resolve: {
   alias: {
    'react': 'react-lite',
    'react-dom': 'react-lite'
   }
  }, 
  module: {
  loaders: [
    {
     test: /\.jsx?$/,
     exclude: /(node_modules|bower_components)/,
     loader: 'babel-loader',
     query: {
       presets: ['react', 'es2015', 'stage-0'],
       plugins: [ 'transform-class-properties', 'transform-decorators-legacy'],
     }
   }
 ]
},
output: {
  path: __dirname + "/public/build/",
  filename: "bundle2.min.js"
},
plugins: debug ? [] : [
  new webpack.optimize.DedupePlugin(),
  new webpack.optimize.OccurenceOrderPlugin(),
  new webpack.optimize.UglifyJsPlugin(),
  //  new webpack.optimize.AggressiveMergingPlugin()
  new webpack.optimize.UglifyJsPlugin({ mangle: false, sourcemap: false }),
],
};
</code></pre>

<p>I have tried to mark CanvasJS as External, but this did not work either. How can I get Redux to not "run slow", and have references to global objects?</p>
