Webpack uglify doesn't work with trumbowyg

[z-george-ma]

We use trumbowyg + webpack with the following configuration

Preview.js

import React from 'react';
import icons from "trumbowyg/dist/ui/icons.svg"
import Trumbowyg from 'react-trumbowyg'

export class Preview extends React.Component {
  constructor(props, context) {
    super(props, context);

    this.options = [
      'btnGrp-semantic',
      ['link'],
      'btnGrp-justify',
      'btnGrp-lists'
    ];
  }

  componentDidMount() {
  }

  render() {
    return (
      <Trumbowyg 
        id='email'
        buttons={this.options}
        data={this.props.htmlBody}
        onChange={this.props.onChange}
        svgIconsPath={icons}
      />
    )
  }
}

webpack.conf.js

const GLOBALS = {
  'process.env.NODE_ENV': JSON.stringify('production'),
  __DEV__: false
};

export default {
  resolve: {
    extensions: ['', '.js', '.jsx']
  },
  debug: true,
  devtool: 'source-map', // more info:https://webpack.github.io/docs/build-performance.html#sourcemaps and https://webpack.github.io/docs/configuration.html#devtool
  noInfo: true, // set to false to see a list of every file being bundled.
  entry: [
    'babel-polyfill',
    './src/index'
  ],
  target: 'web', // necessary per https://webpack.github.io/docs/testing.html#compile-and-test
  output: {
    path: `${__dirname}/dist`,
    publicPath: './',
    filename: '[name].[chunkhash].js'
  },
  plugins: [
    // Hash the files using MD5 so that their names change when the content changes.
    new WebpackMd5Hash(),

    // Optimize the order that items are bundled. This assures the hash is deterministic.

      },
      inject: true
    }),

    // Eliminate duplicate packages when generating bundle
    new webpack.optimize.DedupePlugin(),

    // Minify JS
    new webpack.optimize.UglifyJsPlugin(),
    
    new webpack.ProvidePlugin({
      $: "jquery",
      jQuery: "jquery"
    }) 
  ],
  module: {
    loaders: [
      {test: /\.jsx?$/, exclude: /node_modules/, loader: 'babel'},
      {test: /\.eot(\?v=\d+.\d+.\d+)?$/, loader: 'url?name=[name].[ext]'},
      {test: /\.woff(2)?(\?v=[0-9]\.[0-9]\.[0-9])?$/, loader: "url?limit=10000&mimetype=application/font-woff&name=[name].[ext]"},
      {test: /\.ttf(\?v=\d+.\d+.\d+)?$/, loader: 'url?limit=10000&mimetype=application/octet-stream&name=[name].[ext]'},
      {test: /\.svg(\?v=\d+.\d+.\d+)?$/, loader: 'url?limit=10000&mimetype=image/svg+xml&name=[name].[ext]'},
      {test: /\.(jpe?g|png|gif)$/i, loader: 'file?name=[name].[ext]'},
      {test: /\.ico$/, loader: 'file?name=[name].[ext]'},
      {test: /(\.css|\.less)$/, loader: ExtractTextPlugin.extract('css?sourceMap!postcss!less?sourceMap')}
    ]
  },
  postcss: ()=> [autoprefixer]
};

The build artefact doesn't work correctly, but commenting out new webpack.optimize.UglifyJsPlugin() works.

Maybe it doesn't work because UglifyJs spoil the global vars names. Try to change uglufy settings to less aggressive

I've had this problem before out of the scope Trumbowyg where Uglify complains that it can't take es6 code. Since then, I switched over to babel-minify-webpack-plugin. I hope that helps.
