Make UglifyJsPlugin optional/configurable

[allfreelancers]

HI!
// todo - options here should be configurable
new webpack.optimize.UglifyJsPlugin({
sourceMap: this.webpackConfig.useSourceMaps
})

Can you make it optional/configurable? I have an error:
app.b452c69496e2c9f0cbd2.js from UglifyJs

what is the error message you get ?

Error :
app.8eaba82891470d4ca570.js from UglifyJs
Unexpected token: punc (() [app.8eaba82891470d4ca570.js:204,8]

The solution of the problem is possible:
webpack/webpack#1542

[stof]

yeah, UglifyJS currently does not support minifying ES6 code. You need to transpile it to ES5 with Babel first.

Closing - see #139 also for more details

For anyone else that comes here looking for a solution:
If you use babel-preset-env, set the option targets.uglify to true in your babel presets.
