Failed to minify on production build

Ok, so I created a new react app with create-react-app, added react-plotly.js to my project/code, ran into the “using glsify without its transform applied” problem (issue #13), and after reading through the various solutions, opted to do a npm run eject so I could add ify-loader to my webpack.config.dev.js and webpack.config.prod.js (ala https://github.com/plotly/plotly.js#building-plotlyjs-with-webpack).

This fixed the problem in dev mode, and I can get my <Plot> component to display just fine when running the dev server (npm start). However, now if I try to do a ‘npm run build’ to build a production version, I get the following error:

Failed to compile.

Failed to minify the code from this file: 

 	./node_modules/ify-loader!./node_modules/gl-matrix/src/gl-matrix/common.js:28

I’ve looked around, but I can’t seem to find much of a hint on how to fix this… any ideas?

OK, so here’s a webpack configuration that works for me… The issue is resolved by adding the es2015 preset to babel-loader to properly handle gl-matrix 😃

var webpack = require('webpack');

module.exports = {
  entry: "./index.js",
  output: {
    path: __dirname,
    filename: "bundle.webpack.js"
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        use: {
          loader: 'babel-loader',
          options: {
            "presets" : [["es2015", {modules: false}], "react"],
          }
        }
      },
      {
        test: /\.js$/,
        use: 'ify-loader',
      },
      {
        test: /\.js$/,
        use: 'transform-loader?plotly.js/tasks/util/compress_attributes.js',
      }
    ]
  },
  plugins: [
    new webpack.DefinePlugin({'process.env.NODE_ENV': '"production"'}),
    new webpack.optimize.UglifyJsPlugin({
      ie8: false,
      mangle: {
        except: ['$super', '$', 'exports', 'require']
      }
    })
  ]
};

You’ll need the following modules:

    "babel-core": "^6.26.0",
    "babel-loader": "^7.1.2",
    "babel-preset-es2015": "^6.24.1",
    "babel-preset-react": "^6.24.1",
    "ify-loader": "^1.1.0",
    "plotly.js": "^1.33.0",
    "react": "^16.2.0",
    "react-dom": "^16.2.0",
    "react-plotly.js": "^1.2.0",
    "transform-loader": "^0.2.4",
    "webpack": "^3.10.0"

Same here.
