title: You are currently using minified code outside of NODE_ENV === "production"
body: <p>I am getting the error like this</p>
  <pre><code>You are currently using minified code outside of NODE_ENV === &quot;production&quot;. 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.

  <p>I recently upgraded my project to angular 9 from angular 6.</p>
  <p>I also tried
  1)&quot;webpack:server&quot;: &quot;webpack --mode production --config webpack.server.config.js --progress --colors&quot;,
  2)&quot;webpack:server&quot;: &quot;webpack -p --config webpack.server.config.js --progress --colors&quot;,
  3)new webpack.DefinePlugin({
  'process.env': {
  'NODE_ENV': JSON.stringify('production')
  }
  })
  4)new webpack.DefinePlugin({
  'process.env.NODE_ENV': JSON.stringify('production')
  })</p>
  <pre><code>5)new webpack.optimize.UglifyJsPlugin({
        include: /\.min\.js$/,
        minimize: true
      })
