The repo provided is using an old version of uglifyjs-webpack-plugin that uses uglify-js which is ES5 only:
uglifyjs-webpack-plugin@1.0.0-beta.2 uses the ES6+ capable uglify-es module.
The repo's webpack@2.6.1 prod config is also pointing an ES5 only uglify-js webpack uglify plugin:

}@moimael just for check, can your add "uglify": true to targets section? Btw some babel plugins can output non standard syntax, which doesn't support by uglify-es.
moimael
commented
7 years ago So I tried something and think I found the issue. If I use webpack -p even when specifying the uglify js plugin 1.0.0-beta2, it seems like webpack is using the builtin plugin. On the other end, if I use webpack --define process.env.NODE_ENV=production, my code correctly use the beta2 version and my code is minified without errors. It's very confusing though.

commented
7 years ago @moimael known issue (after stable release, it will avoid), here in issues was solution (plugin) how unpin default webpack uglify plugin. Can we close issue?
jlengstorf
commented
7 years ago I ran into this error and was able to fix it by adding "uglify": true to babel-preset-env's targets in my .babelrc:
{
"plugins": ["transform-object-rest-spread"],
"presets": [
"react",
[
"env",
{
"targets": { "node": "6.9.0", "uglify": true },
"useBuiltIns": true
}
]
]
}@jlengstorf Be aware that if you use Babel's uglify target it's an alias for ES5 code generation. It came out before uglify-es.
https://github.com/babel/babel-preset-env/pull/178
If you want to minify ES6 code without transforming to ES5, you wouldn't want to use that.
Working ES6 webpack uglify-es example:

commented
7 years ago @kzc Thanks for this! After looking at my config again, I realized that the problem was that I had the -p flag set for webpack, so it was trying to run the built-in UglifyJS plugin.
Disabling that and switching to webpack.DefinePlugin (to set process.env.NODE_ENV="production") fixed the problem — no modifications required to babel-preset-env.

7 years ago thank you @jlengstorf. Setting uglify to true worked for me as well, I am just here to remind others who also want to use solution, you need babel-preset-env .

6 years ago UPDATE: The uglify target (ie. uglify: true) has been deprecated in @babel/preset-env. Set the top level option forceAllTransforms: true instead:
presets: [
['@babel/preset-env', {
shippedProposals: true, // to support spread operators
forceAllTransforms: true
}]

6 years ago Just adding to summarize what worked for me: webpack 3.10.0 internally uses UglifyJsPlugin 0.4.6 which it exposes by default as webpack.optimize.UglifyJsPlugin for use inside webpack.cofig.js. however this version does not support es2015. what I based on what other people wrote in this thread was:
upgraded the following to devDependencies section of package.json : "webpack":"3.10.0"
1) added the following to devDependencies section of package.json : "uglifyjs-webpack-plugin":"1.1.6",
2) modified webpack.config.js so that the following:
new webpack.optimize.UglifyJsPlugin({
sourceMap: true,
ecma:8,
compress: {
warnings: false
}was replaced with:
new UglifyJsPlugin({
sourceMap: true,
uglifyOptions: {
ecma:8,
compress: {
warnings: false
}
}
}),and added const UglifyJsPlugin = require('uglifyjs-webpack-plugin') near the top of the webpack.config.js file.
I hope this would sort things out for someone.

6 years ago I was still running into issues, so I thought I'd also post for anyone that may still run into issues.
I had to stop running webpack with the -p flag, and set it to production using webpack.DefinePlugin && define the UglifyJsPlugin options, then running webpack --progress --colors etc.
Using Uglify isn't necessary to stop the the error in this instance, setting production through DefinePlugin works, but it compiled my server from 16kb down to 6kb with uglify, SO I left it in.

6 years ago With following:
"uglifyjs-webpack-plugin": "^1.1.6",
"webpack": "^3.11.0",I got this error:
ERROR in bundle.js from UglifyJs Unexpected token: punc ({)
I tired @matthew-gordon and @epeleg 's solutions, but doesn't work.
With @matthew-gordon's solution, the error doesn't show up, but the size of bundle.js is +380KB
With @epeleg's solution, bundle.js size is ~180KB, but I got that error.
Both minified.
Did I miss something?
Using the latest beta 2 release, i still can't compile our project with webpack and uglify js. I get a bunch of errors:
I specified the
ecma: 8option. Any idea why this happens ?Thanks !
