I'm trying to build my project that uses webpack. My UglifyJS options looks like this:
new UglifyJSPlugin({
sourceMap: false,
uglifyOptions: {
compress: {
warnings: false,
},
output: {
comments: false,
},
},
}),
What I get is an error:
Unexpected token: punc ()) [index-3d0ae630eaa0a0128a00.js:145853,20]
I have found some SO topic saying that this might be a problem with webpack uglify plugin, but I've already switched to an uglifyjs-webpack-plugin
.
Any ideas?
I had the same error and was able to fix it by:
npm i -D uglifyjs-webpack-plugin@beta
)"uglifyjs": true
to the targets inbabel-preset-env
If you're using the env preset, try updating the targets in your
.babelrc
:There is also an issue on the plugin repo that lists other possible solutions.
