npm run production fail to uglify

Hi all,

• Laravel Mix Version: 0.11.4
• Node Version : 6.10.3
• NPM Version : 4.6.1
• OS: OSX 10.11.6

Description: when run : npm run production it faill with error on uglify

(Unexpected token: punc (() … )

It seam to be a babel error but can’t resolve that.

I’ have add an .babelrc with { 'presets': [ ['es2015', { 'modules': false }] ] }

but it didnt resolve the pbm.

Any one have some way to point me to solution ?

I also has same issue with uglify. My current workaround is to use Babili. my webpack.mix.js

const { mix } = require('laravel-mix');
const BabiliPlugin = require('babili-webpack-plugin');
const webpack = require('webpack');
const webpackConfig = {
 ...
};

...

if (mix.config.inProduction) {
    webpackConfig.plugins.push(new BabiliPlugin());

    mix.options({
        uglify: false
    });
    mix.disableNotifications();
    //    mix.version();
    
} else {
    mix.sourceMaps();
}

mix.webpackConfig(webpackConfig);

I just had this Unexpected token: punc issue, and this is how I resolved it, @fbmfbm:

My .babelrc was:

{
  "plugins": ["transform-object-rest-spread"]
}

I have changed it to:

{
  "presets": [
    ["env", {
      "modules": false,
      "targets": {
          "browsers": ["> 2%"],
          "uglify": true
      }
    }]
  ],
  "plugins": ["transform-object-rest-spread"]
}

The fact is: when we use a custom .babelrc file, the default Laravel Mix configuration for babel is lost.

So, I have prepended the lost default configuration to my custom .babelrc configuration, and got it working.
